Lee -
I rarely turn mine above 11 o'clock. What speaker are you using?? The
amplifier is designed for a 4 ohm speaker. An 8 ohm speaker (MUCH more
common these days) will reduce the overall output.
Try bridging C176. A high ESR (dried out) cap here will reduce the gain
of the stage considerably. Also verify approximately 4.5 VDC on the
Cathode (Pin 1) of V7.

I have a R-4B here that I'm thinking is still low on audio output??
For those that have one too....where is the 'normal' setting of the AF
gain for you....
For a pretty loud level, not super loud just a nice loud level you
could here fine on loud signals of S9 or so .
What setting on yours would you consider super loud and want to turn it
down?
Seems like I have to use around 1:00 on the AF gain to get decent
loudness.
I'm just trying to find out if my audio is pretty normal??
Thanks,
