You could stick a few transistors more in that thing!

Patience, this is Mr Popa's first shot.

Next one may have an output stage with 9 pairs of 230W power devices, 90V rails, and go by the name OP-WAN.
And a cheaper input opamp model, the Hello OAP-3500.

(still 6 months lead time on the Onsemi TT-devices, pff)

It is my own design and construction.

Its basically an SRPP valve front end with a fairly standard class AB SS amplifier with IRFP920/9240 on the output.

Yea, why waste so much empty PCB space?

Not environmentally friendly there.

You ought to be able to cram the PCB with lots of them.

...like this....
