Crate GT-80 schematic

[oDave]

Looking for Crate GT-80 schematic.
Have one that seems hard on 12au7's, not sure tube placement is correct. Curious as to possible subs and want to check the supply.

Thanks

Personally I'd stick to two 12AU7s and a 12AX7. Looking at the three tubes as a row, the 12AX7 is the one in the middle.
