Got another project, a A.Davoli 8092 K (very different from the newer 40W 8092 KB model) but can't find much about this.
I do get this is a mono push pull with EL34 output tubes from 1965
Can anyone see from the schematic if this is a Class A or AB?
And how much output power?
It also have a strange impedance selector, with connector is 0? Is is ground?
Is phono (Fono in schematic) a line in or a RIAA stage?
It is missing some fuseholders and the magic eye so i can't measure plate voltage yet.

Class AB - class AB would be 20W or so, AB considerably more depending on the B+ and transformer impedance.
Yes, 0 is ground or speaker common.
Fono is high level, one less gain stage than microphone.

You are missing EM87 , i can get that for you.
Power tubes are EL36 ( tv horisontal scan tubes )
The "fono" input seems to be a line input as it looks like tonecontrols and
too little amplification for a magnetic cartridge.
Power : a guess 50w. If you want more , send it to me and i will
test it ( and supply missing parts if you like )
Address : sweden etc.
