Hi everyone.
I was wondering if i could substitute this tube safely in the 12au7 position in the pilot amp.
I tried it briefly and the difference was not subtle.
I understand that i have to watch the heater current but i dont know what or how to check.
any help would be appreciated.
the schematic can be found here
