- Here's my take on all this. After reading the various post I am 99.999999% sure it is an ac 240v line problem. Both legs of the ac line and the neutral to both legs should be tested under load. Simpl

- There is an up side to going to the 572b. It is a common practice in the 30L-1 without any problems that I know of. Seeing how the 572b is a stronger tube it would last a lot longer at higher drive l
