Alright. Just bought this....



I guess most of us are familiar with the old Klein&Hummel PA jobbies,this though is a dedicated guitar amp.



Seller is a friend of mine and he told that it uses 4pcs of 7355 powertubes.



Tagboard design as clearly seen.

Does anyone of you guys out there have any info on this unit? Anything from background stories to a schematic.?
