Help guys. I have a president Washington 858pll. It all of a sudden stopped transmitting tonight. At first I thought it was the final, but I had a 2166 driver and 1969 final from another radio and nothing. It receives fine, and the relay clicks. I hooked up external speakers to the PA jack and the recieve comes out of it, and i can talk out of it. I am sorta stuck here, anyone have any ideas"s Thank you!
