I recently acquired an old Magnatone MP3 amp, and the seller removed all the tubes and packed separately (which I appreciated), but he didn't provide any info as to which sockets they go in. I have the schematic for the amp, but doesn't help me with installing them correctly, just how they tie into the circuit. It's obvious where the two power tubes go, but there are 3-12AX7s, 2-12DW7s and one- 12AU7. Would any of you be able to provide with a tube layout chart? This isn't something I'm going to guess at!! Thanks so much!
