Is my Dynaco Stereo 400 worth repairing for resale?


After all the years, I’m sure it needs a good cleaning and at least all the cans replaced.

Will I even break even?

Will Vincent or Tubes for hifi both rebuild but they basically use the case and transformer.  Those are 1700-2000.  They sell kits as well.  

We used to have Magnapans.   We used Ampzilla and Quattre.  Both blew up. There were some reliability improvements that can be made. Bonjoirno and Leach put solid state on the right path.  Much more pleasant sounding than many of the day.

How much do you like it? How much would it cost to replace? How long do you plan on keeping it?

If you get all the electrolytic caps replaced, along with any other out of spec part, the amp should last another 20 or so years with out issues, other then cleaning. 

If you love it, fix it, if not sell it for something you will love. 

In the last 6 months have referbed 3 of my amps, and 2 of my pre-amps. All sounded so much better after, it was way more sweat equity over cost as I DIY'ed it. Cost was about $80 per piece, sans the amps big power caps. 

This guy, old and in the way, enjoyed this thread.  I've got a dead Superphon in storage. I keep thinking I'll get it fixed some day.

Yeah, it’s been used once in the last couple years and should probably move to a home where it’s going to be used, but….  can you send me a link to Big E?

The Stereo 400 was a kit and it has a ton of parts, but if I can bring it back to spec, or better yet, I might just keep it around. 😁
