I have a 460A amp that I have modified for stand alone use following advice from other AK threads. This amp was non operational when I started (bunt output transformer). I have replaced all electrolytic caps, coupling caps, the top hat diodes (1N007), tested every resistor in the amp, and have brand new tubes. The good news is the amp is now operational, the problem is my B+ voltage is 410v after warm up which is 25v to high. This causes my grid (pin 9 370v) and plate (pin 7 400v) to run high also. How can I drop my B+ by 25v to solve this problem or is it fine to run this way? I have not ran it for mare than 5 minutes since completion last night. Mods: C93B, C93C, R124, R127 Removed, 350 ohm 20w across C93A, and increasing R123 to 7k ohm 3W.
