Hi folks,
A young student of mine has been give an old valve amp. We think it is an old reel to reel projector amp. Two of the valves are easily identified as 6V4 and 6CA7 (EL34) but the third has its label rubbed off. I'm hoping someone here may be able to help identify the mystery valve.
Here are the pics...
Unknown valve
Its a neat little amp with a 2ohm speaker which sounds pretty good and clean until it beaks down after a minute or so with what is either a dud transformer or shoddy valves. Its pretty microphonic so if we can identify the mystery valve we'll replace them and see where to next. Its point to point wiring internally and pretty clean at that ( I didn't get a pic sadly).
Hopefully the amp gurus here can point us in the right direction
Cheers,
Mick
