**HELP**. Egnater M4 Question

Post by mfred » Wed Jan 08, 2020 7:48 pm

I just purchased a used Egnater Dual Channel M4 Preamp. My question is there are two tubes in the main chassis. (From the Back, Upper Right- Lower Left Diagonally). My unit came with two JJ 12AX7A tubes installed. Is this the correct tube for my unit? I read somewhere that one was supposed to be a 12AT7. Please help
