Is it same as an ITT?
ITT KP1020 BC131 BC107 AC131 AC186
The RGD P10 is ITT branded on vents / cover

OR
More beefy ITT KP1080 BC131 BC131 BC236 BFS60K AD161 AD162
http://www.radiomuseum.org/r/ittgb_kp1080.html
(They look similar to RGD P10 and both have schematics)
Anyway can't be hard to trace. I sometimes brightly light underneath, or scan/photo both sides and do semi-transparent merge. It ought to be simple.
As Mark says the most common issue is pot or diode or transistor bias on input to last stage.
