Everything is working fine with the exception of the 10M band where the plate current takes off well over 300 mA regardless of where the gain control is set.
Neutralization looks good on 15M so assuming it is breaking into oscillation due to the lack of shielding provided by the RF cage?
Hoping that someone in this group may have a parts unit with the RF cage that they would be willing to sell or trade?
I believe that the RF cage is the same for all of the T-4 series transmitters?
Appreciate any assistance.
