K-502 Valve Amplifier Kit

It is no surprise seeing another build of the S-5 Electronics Tube Amplifier Kits. These valve amplifier kits are inexpensive, simple to build, fun and best of all, they sound great.

Pictured below is Scott's build of the inexpensive and popular K-502 Tube Amplifier Kit and Enclosure. The enclosure for this tube amp looks fantastic. Great attention to detail.

Scott only made a few changes to the circuit board; replacing the stock 0.22 uF polyester film caps with good quality Orange Drop capacitors. I lived with a stock build of the S-5 Electronics K-12M Tube Amplifier Kit for a while and I can tell you that this kit does sound very good in stock form. Scott also replaced the standard volume potentiometer with a good quality stepped attenuator.

For additional information and pictures of this tube amp project, see Scott's K-502 Tube Amplifier Kit and Enclosure page.
