Hello,
First off I would like to say hello to everyone here, I have lurked around the site a bit and decided this looks like the place for me. I have been into audio equipment for quite sometime and consider myself experienced (a little at least) in trouble shooting, repair, and restoration of solid state equipment. After reading the many reviews and posts on the s-5 tube kits I decided to order the K-502. Being the "hobbyist" that I am I couldn't just build the kit as intended and decided to do some mods. I built a chassis, upgraded coupling caps, installed snubbers across filaments and HV, removed dc blocking caps from signal path, used a uf4007 from bridge rectifier to filter cap, upgraded binding posts and rca jacks and upgraded volume pot. After finishing the project I get absolutely no output . The tubes glow fine and there is no sign of the obvious such as bad soldier joints, reversed polarity on components ect.. Nothing is shorting out or hot. I know there is several threads on this amp and I have spent hr researching and thought it would be best to post here and ask the experts for help. I came across a thread recently where a member was having a similar problem with a K-12 kit and it ended up being a grounding issue with the binding posts, I don't think that is the issue here though. Also I see the Voltsecond mods mentioned on almost all the threads, his webpage seems to be out of commission does anyone know where I could access this info? All info and help would be greatly appreciated. BTW I haven't took any measurement's yet and hope to get a chance to work on it a little more tonight.
Thanks,
Jason
