OK, thanks Walter. The tuner module looks like some one has been in there in
the past so I have not looked their. I will do this now and remove that cap.
I have also bypassed the regulator and removed the H.O.T but the driver
pulse is there but pulsing as I said. If I can get a stable pulse then will
install the H.O.T. These transistors cost us $10 each don't want to takeout
any more, lost 2 already.
thanks
Bruce.
