Maybe some clarity.. stock early 60's lineup there for a bit of a monster..
ECC85 - VHF tuner etc.. ECH81 - theres our L/M/S .. now then faf801?? .. EF80/6 IF amp? makes sense to my thinking.. ECL86x2 .. depends if mono or stereo.. for mono audio driver one triode.. phase splitter second and push pull output stage or.. pair of triode drivers with class a outputs for stereo..
and the EM37 ??.. strange choice.. tuning indicator (sell if working and fit a posh meter I would say)
If it's a mono push-pull it's LOUD!!! because I had an amp of that configuration in an Ekco gram years ago and it was a very effective guitar amp with a little play about on the input side.
There aren't gong to be any great surprises in the circuitry in there. By the Ex8* series valves things had become very "same same". I can see it now.. a large printed panel with a big am/fm/gram switch running down the middle of it and valves sitting in brown scorch marks along the back edge in the company of 2 nice silver cased IF transformers either side of the EF80/6 (where is the EABC80?.. it's missing, but probably replaced with a couple of germanium diodes)
I think it should work well with a minimum of fuss.. often these late series valve things just work. Even 240 down the 110 won't have done much harm as the silicon rectifiers give up the ghost and go o/c when they get 500v up them.. which was why my Laney was dead when I got it... Blown rectifiers and a burnt to a crisp choke. (need to do something about that one day.. redesign of the psu required.. along with some "legal colours" mains cable)
