Around the Standel 25L15 seems there is real interest
this amp porn seems from an original one, so I hope someone is interested to see

The pictures in the early section of the thread are from the modern Standel company, not the 1950's original amp. Be aware the power chassis has a bunch of additions not found on the original.
The original at the bottom isn't hi-resolution enough to make out any values. Also, Standel used Vector tube sockets so most of the preamp parts are mounted on the sockets and are not visible in the photo. Of course, you also get no pictures inside the power chassis.
That's a pretty tough way to try to decipher the circuit.

So I misunderstand, I was thinking the black chassis was a reissue and the green chassis an original '50 chassis
about the other chassis it was a transition prototype between the 25L15 and the 50L15---
Standel used Vector tube sockets
Ah, something like this

I saw T-Rex at the New Orleans Pop Festival in 1969 just a few weeks from the time of Woodstock. I'd forgotten about them. Don't remember what amps they might have used for the show?
With respect, Tubenit
