Tubes Asylum Questions about tubes and gear that glows. FAQ |
|
Hello,
I recently acquired a mid to late 60's Marco Polo (Japanese) guitar amp. It uses 7 pin tubes throughout but I've not been able to find any information on these tubes and I hope someone here can help. The tubes are:
Preamp/tremolo: NEC 4Y
Power amp 1: NEC 4X
Power amp 2: NEC 48
Note that the 4X and 48 look identical.
Any information you may have would be greatly appreciated. Equivalents? Pin outs? Etc.
Thanks.
