HiFi (Chifi) tube amp build - but my own design.

Tim,
I have some bakelite sockets in my work shop that I can dig up. I believe quite a few are NOS. I will take photos tomorrow and if you're interested you can have them for the cost of shipping.

Tim - Photos of 8 octal tube sockets. (Top and bottom)
Send me a PM if you're interested.

Thanks Rod for the offer but I don't think those would work. There's some differences in the sizing and mounting holes between China (slotted screw holes) and NOS USA tube sockets. I've tried some others and nothing lines up. I'd have to pull parts and grind my tube socket holes larger. I do have some ceramic ones coming in from over seas that measure correctly. I ordered several different types so hopefully I'll get something that will work.

I got some new ceramic octal tube sockets installed and also tried some different coupling caps.
The results: The good - both tubes light up  The bad - sounds awful! Ok, so just why? Maybe my coupling caps. I tried some generic yellow .33 caps that came with a kit. I wasn't super pleased with the brown drop caps I had in there previously, so I tried those. So, I'll try something else. Maybe some of those highly sought after leaky bumble bees  I'll also use some socket adapters and check voltages so I can see if the new sockets are working. Voltages at the pins check ok. May be time to break out the scope again. It'd be great for a guitar player - just the right distortion, but for HiFi - not so much.

Well, maybe - maybe not
It's been an interesting project so far! Something so simple, yet so cranky. The 1st one worked perfect, aside from some static from those lousy tube sockets, a little wiggling and it clears up. THIS ONE, been a challenge. Identical, but not identical. The 1st one worked so good that I don't want to touch it, then there's this one. Probably some dumb simple thing that I've overlooked. Well, it's like this - only a real car guy can understand! You never really finish a classic car! There's always something else
