Vox Ac15 1959/1960 schematic differences?

[LustandFury]

I'm thinking of building a Vox AC15 type circuit into a B&H Filmosound projector amp I found. I seems to have all the basic parts. 2 12AX7's, EF86 EZ81 and two EL84's...what is the difference between the 1959 schematic and the 1960 schematic that is floating around the web? And are there any clearer schematics for this amp floating around?

oh ya Minus the Trem because the chassis is SUPER small.

The 1959 one has an ECF82 as V2, I think. Use the 1960 schematic.

Ah I see! Thanks.

At some point the EF86 started being wired as a triode rather than a pentode. This was apparently an effort to dummy them down... because excessive noise/microphonics?
