Sertech Electronics Repair

I called them to see if they can fix my Car Audio speaker, they said they weren’t sure, so I offered to send email with pictures of the speaker.
They did not call me back.
So I called back telling them i sent them Email, the guy tells me they will get back to me.
Nobody responded to me ever after.
I’m not wasting my time calling them 3times for the same thing.

I am from Santa Cruz & after exhausting all the resources for stereo repair in the area, I got pointed to Sertech.
Norman is the man. I have a stereo unit, over 40 years of age (1977) that needed to be brought back from the dead. The places in the Santa Cruz area were not cutting it.
Reasonably priced & excellent service; very nice people at Sertech.
There are also units that are for sale; nothing like the classic analogue units to bring that sound out from audio tape & vinyl.
I highly recommend this business next to a hydroponic shop, not too far of a fetch of the Santa Cruz minded.

My equipment repair was never finished, never returned.

Robert installed a home theater system for me and Norman did the follow-​up to make it sound perfect. Highly recommend this unpretentious, friendly place.

Got my 30 year old Nakamichi receiver cleaned-​up and tuned-​up by Stretch. They did a great job and my only gripe is they were so busy that they never called me to let me know my receiver was ready for pick-​up. They said they were backed-​up with jobs when I dropped-​off my receiver, and it will take 5 weeks before they can even start the repair job. But I never heard back from them so I gave them a call, then they could not find my receiver so I had to wait for them to call back. These guys are super busy and it will take awhile to get your equipment repaired, but I was pleased they revived my Nakamichi and got it running again, and the repair was not too expensive.

Great place to get that vintage stereo equipment repaired.
Had my Pioneer RT-​909 serviced here.
Runs and sounds beautiful.
I had taken it to R and B, and McAlister Electronics, who couldnt fix it.
This place is great. and it was much less than i expected to pay.

I brought my Pioneer SX-​1250 in to Sertech for a complete overhaul. The results were amazing and better than I expected. Sonically the amplifier is better than new and they were able to completely fix what minor damage had occurred over the years. Norm and Robert are very knowledgeable about the old analog receivers and other stereo components. They are doing a great job keeping them alive. Great service and quality work. The best place to go for stereo equipment repair!

They fixed my ancient Harmon Kardon receiver at a reasonable price and right on schedule. I found them using Unilocal and ignored the few reviews that complained about delivery time … I found their estimates on delivery very reasonable for this type of work. If you have old stereo equipment and want honest, reasonable repair go here!

Sertech is my go-​to place for stereo repair. Norm is knowledgable beyond compare. I have collected vintage stereo gear for years and whenever something is in need of repair, Sertech can fix it.
Word of caution: Sertech is a two man shop. Sertech services the entire South Bay Area and further. While there might be other repair shops like Sertech, I do not know of any. That being said, Sertech is very busy. It could take a month to repair your equipment. Be patient. Your work will get done, and it will be fixed correctly and inexpensively.

Great service. Had a quick repair to be done and it was taken care of on the spot! Reasonable price and I’m happy with my repaired monitor. Thanks!

Took a complicated amplifier to Norman at Sertech. Rather then turn me away because it was not anything he was familiar with Norman took the challenge to repair it. Unfortunately they couldn’t get parts which was not their fault. But I give Sertech high marks for the effort.
Be prepared to wait a bit for repairs as it is a small shop. But I will definitely use them again.

Found this place on Craigslist and happy that I did. Originally came here to have my Marantz 2275 repaired and Norman the owner did a fantastic job! Robert who also works here is very helpful and friendly sold me a set of pioneer HPM-​100 to go along with my receiver thanks again for the demo Robert! Over all I highly recommend this place to have any of your electronics vintage or new repaired!

Not a very professional customer service experience for me. I took in my receiver, which wasn’t making any sound. The interesting old-​time stereo enthusiast at the store told me they’d take a look and get back to me with an estimate. But, he said they were busy and it might take two weeks to get back to me.
After 3+ weeks and no call, I called the store. The gentleman said they had looked at it and an expensive component in the receiver was not working, and the price of a new component was about $ 300. He said he was trying to find a lower-​priced part on the Internet.
It’s been months and I haven’t heard back from them. As far as I’m concerned, the stereo is a goner. I haven’t pressed to get it back because it would just be a boat anchor to me. And I’m not complaining more because they haven’t charged me to do whatever diagnosis they did.
In summary, it was not a successful repair experience for me, and customer service (getting a call-​back and being informed) was sub-​par. But, they seem enthusiastic and seasoned, so maybe they’re more successful for other customers.

My Boston Acoustics subwoofer died and someone referred me to Sertech.
Short and simple — they did a great job for a reasonable price.

The SME Norman repaired my Mcintosh tube amp in weeks and fixed some inherent issues probably from the 60’s.
It works and sounds great now. Cost is reasonable.
One thing worth mentioning is that you do have to call to check the status, and that he does not perform /​charge for unnecessary repairs!
I got a few more pieces to go too.

Go here for your repairs. I brought a mid-​1970s Marantz 2230 receiver here to be fixed. It had several problems. They replaced all 6 transistors, all the lamps (lightbulbs), de-​gummed the power button, and re-​aligned the radio tuning wheel. This was my dad’s receiver that he had my whole life, and it has never looked or worked this good; I’m really happy now.
I felt the price charged was reasonable. It was $ 30 down for an analysis (you don’t get that back per se, but they do credit that toward the final bill). The final bill was right at $ 200.
It took them about a week to get around to doing the analysis, and just another day to do the fix. They seem to get a lot of business here and I guess are constantly full of units to fix. Another review mentioned that you should call them to check up. I would recommend that too, but make sure to give a respectable amount of time before calling (if he says 8 days, give him a full 8 days before calling).

I don’t generally like to give a review with this low a rating. However based on my personal experience I think two stars is a fair rating for this business. Let me start by saying that Norman, the gentleman who operates Sertech, is a very nice man and a real pleasure to talk with. He seems to be knowledgeable on all types of Hi Fi equipment as well. I am also fully aware that the equipment I brought in for repair is «vintage» and, perhaps not so easy to repair. However, I believe that Sertech’s specialty is supposed to be the repair of vintage HiFI & stereo equipment. Among other things they also produce high quality stereo speakers and resale used/​collectible equipment.
At any rate here are some details of my experiences with Sertech: All three stereo components I took in for repair; a Mac 1900 stereo receiver, a Phillips GA 312 turntable and a Yamaha CR 620 receiver had to be returned to them for further repairs. In other words all three pieces were «come backs» for more repairs that could have and should have been diagnosed & completed the first time in the shop. I feel at the very least I should have been told, when I picked up and paid for the repairs, that there are still issues with how the units sound/​play. Also I should have been offered a demo of the equipment to make sure it is working properly before taking it back home. Instead I trusted that they had completed the repairs and gave them «the benefit of the doubt». This was my mistake to be sure. After bringing the equipment home and hooking it up to play, it was very frustrating to find out the repairs had not been completed. It really makes me wonder if they even check their work before releasing the equipment back to the customer! By the way, on each of these components, the price for the repairs was no issue and they had instructions to «go through» everything to make sure all the functions/​controls are working and sounding as they should. On the Yamaha receiver for example there are still «dirty pots» that make static noise when they are operated. This is after two stays at Sertech when they were supposed to do a complete check up on the unit and were specifically asked to clean and lube all the controls. On the Phillips turntable for example they had two attempts to repair the hum on the right channel. New RCA cables were even installed. Yet the hum still persist. and is in fact worse than before I took the table into them. Now instead of bringing the turntable into them for a third time I have decided to find another repair service that will hopefully resolve the problem (I plan to write a review of this other service after the turntable issue is resolved).
Lastly I have found the communication from Sertech to be poor at best. Based on my experiences If one doesn’t make an attempt to contact them, months can pass before one gets a call from them regarding the status of the repairs. The bottom line is I won’t be going back to Sertech and will have to find another repair service that will hopefully get things right the first time around and provide a higher level of customer service.

I chose these Sertech over the only other competant McIntosh stereo repair I know of up near the Cow Palace for the proximity plus, one of the high end stereo online forums has great things to say about him.
They are right, Norman is an expert and he fixed and cleaned up my two pieces of 30+ year old McIntosh stereo gear for a very reasonable cost. $ 30.00 per item eval/​troubleshooting fee but it is applied to the repair.
Definitely an ‘old school’ experience, don’t let the disheveled appearance of the shop put you off. He’s an electronics guru not a decorator. And you do need to call on the date it’s to be done and check in yourself, as others say here, he’s not going to chase you on the telephone.
A little hard to find, it’s on Winfield about a block south of Blossom Hill near the mall there, and take a right into the little low end office strip right past the water slide! He’s at the far end, plenty of parking. And while there, get a demo of his amazing, hand crafted stereo speakers, these are like nothing you’ll ever hear anywhere else. Thanks Norman!

They recently fixed my Harmon Kardon surround sound AVR. They have a low diagnosis fee of only $ 30 which is great. Their prices are resonable too.
The thing that keeps them from getting 5-​stars: They diagnosed my equipment and never called or emailed to let me know they had figured it out. After a few weeks I emailed (no response) and finally called to find out the status. I approved the repair and they repaired it the next day.

I had a color problem with my old 40″ Mitsubishi TV so I gave Sertech a call. Norman is the owner and is a electronics geek =)
He can pretty much troubleshoot any piece of current electronics gear as long as he has the blueprint/​diagram.
Prices are reasonable and he is punctual. He moved from the Branham lane store and is now on Winfield across the street from Oakridge mall.
He also makes high end stereo speakers that sound really great. They run on 1 watt ! Amazing… You’ll have to hear them to appreciate them. Give him a call if you have TV or Stereo issues.
