[ARC5] R-27/ARC-5 Hookup Question

[J. Forster]

Roughly, yes, except in the dyno powered connection there is an C-L-C
filter between the output stage, which is directly on the dyno B+
terminal, and the earlier stages of the receiver.

I don't know if that choke will handle the DC current of the output stage
without failure, if powered from the rear connector.
