Default (v?)Tailor PA-500 Tube Amp

Okay, so .. I found this amp ..
Let me just begin with saying that .. it just looks like a goddamn BEAST. I cannot believe the power and output transformers on this thing and the tubes ... oh my god! The bad thing is is that it looks really REALLY old and rust has gripped i very tightly. But I do think that there is hope for this fallen tube(or should I say BOTTLE?) amp and I plan a very thorough restoration process .. BUT! .. no schematic anywhere and it looks like quite a complicated design.

So I would like to ask if Anyone has any info or best of all .. A SCHEMATIC(yum) for this monster. Pics bellow ... (Very gratefull in advance!!! )

It just looks really dirty. A pic of the internals would help assess its condition a bit better though. I'm guessing its a pa amp. Looks awfully small for a 500 watt tube amp though.

Or does it only have a tube driver and semi final?

Looks like a solid state PA to me.. Note that LED indicators did not come into widespread use until a decade or so after the end of the tube era.

Probably has a 12ax in the front end. That way they can say its a tube amp. But on second look it doesn't say vacuum tube amp on it does it? I don't see it. Did the guy mistake capacitors for tubes?

Looks like late 70's early 80's solid state to me, I doubt there are any tubes in it. Can we get a picture of the insides?
