[TenTec] O II sub rcvr audio?

[cx7tt at 4email.net]

Hello All,

Set up for split freq ops with KG4TO xmitting, listening up.  I could
not get any audio from SubRX.  Panel set up just like Fig 4-2 of manual;
Tx VFO B, RX VFO A, SUB RX VFOB.  Audio Menu with headphones set for
Left=Main and Right=Both.  Nothing in right ear....no increase
regardless of Sub AF audio gain control knob. 
I worked the dx, the old fashion way...cycling between A/B.  Also found
that if I selected RX to VFO B the signals were nice and loud but of
course the DX station disappeared.

I tried all different combinations of the audio menu....this is the
original sub rx board, not the RX366. O II original owner since Aug
2006, no problems before.

Any ideas?
