    Seller was extremely helpful with an issue I had on a Sound Valves board I ordered. Despite having worked on tube amps for more than 50 years I had issues in following the instructions. He was quite helpful in correcting my problems. The board, although not quite what I expected is well printed with heavy traces and excellent feed throughs. Shipping was timely. I will use this seller again!

    Nice kit, fast shipping. One caveat, included addendum to terminal pinout is not correct. Board is properly silk screened.

    Very nice circuit board with through plated holes & double-sided traces. Yes, use the build list to install the components. This is my second board I have built and am very pleased with the sound of the new 6GH8 board in the ST-70. Thanks, Daryl B. Indianapolis.

  • Works great, good printed instructions as well.

    Just used it successfully in my Dynaco Super Stereo 70 (two power transformers, two 5AR4 rectifiers, two chokes, two multi-section capacitors), and had no issues with it - bias set up great, the amp sounds wonderful. Warm and musical. Highly recommend! Many thanks!

  • Fits perfectly, but I wish that they had better documentation on the design of the board

  • Nice upgrade/repair for any fully original Dynaco ST-70

    I followed the wiring directions exactly, and it worked perfectly first time. As advertised. Replaced a half-century old original Dynaco circuit board, and the results are stunning. Exceeded expectations.
