Mostly vitamin Q paper in oil caps although some are covered with white tape.
This is a homebrew mono integrated amp with a magnetic phono section and a standard phono section.I plugged my old I-phone 5 in it but I had to use the ceramic input or it would over drive the amp.

The tube complement is pair of 6L6Gs,a 12AX7,a 407a,and a 7f7 loctal.They did a beautiful job building this and I would imagine it's a 1950's circuit.The 407 is a Western Electric tube.I wish I could find a schematic.

 Any manufacturer or date stamps on the trannies, caps, or pots?


Thanks!

I'm guessing the output trafo is a Triad because it looks like the ones on the Ampex amps only larger.See if you find that circuit somewhere because the amp sounds really good.

 That may help place year made and possible manufacturer?

That amp is a homebrew..There is nothing on there that indicates a manufacturer..The controls weren't even labeled except by a label maker.I was hoping someone would recognize the circuit from the tubes but I'm guessing it is pretty conventional..The 407a has a 20v filament and 10v if you parallel.
