Dynaco ST-35 PC boards on Ebay

Just wanted to share my experience that I recently had with a pair of stuffed Dynaco ST-35 boards from Ebay.

The PC board quality is excellent. But the capacitors that come with the boards are not good.

This particular PC board came with WIMA signal caps and some small picofarad cream colored caps that look to have their DNA from Tantalum caps than real Silver Mica.

After many hours of attempting to rid the amp of a raspy distortion in the midrange, I started to swap out the small cream colored caps for real Silver Mica's and the distortion was somewhat reduced.

Finally I replaced the red WIMA caps and the amplifier is now working well.

Granted I saved about $30, but lost time and parts from my stock.

Heads-up on these boards.......
