Its obvious where the power tubes go. The 12ax7s go in the middle two sockets V-1 and V-5......and the 12at7s go in the outside sockets V-2 and V-6, and bias them to 500 millivolts + or - 50millivolts. I got the tube locations from the 502BRC manual.
Jolida 520a - What tubes go where?
I just moved across the country. Like the bonehead that I am, I've evidently packed my owners manual in a secret hiding place and didn't do a good job of storing the tubes in any particular order. I'll find the manual eventually but I want to listen to music while I unpack tonight. Can anyone help me out?
