Folks, some years back I recall a fella who solid stated the whole radio. So I guess a good question here would be how well did he do, as I did not talk to him. I need a pair of 26Z5s. Yes I know I can plug diodes in place of the tubes. Next project is a 56 contract Motorola 390A. I recently finished up a 58 contract Motorola. 73s Russ.
