[R-1051] using T-827H with earlier AM-3924 amp? not AM-3924C

[Nick England]

The T-827H and J models expect -15v on pin V from the amp. This is used in
the audio boards that are different from earlier T-827 models.
The AM-3924 amp manual shows pin V with -30v from the bias circuitry.

Is anyone using this combo of later T-827 and earlier AM-3924 models?

Was there a FC to make them compatible?

Unfortunately, I don't have a URT-23C manual which contains the AM-3924C
schematic - can anyone help??

And I don't have the earlier T-827 manuals either, just the H and J
versions!
