I replaced the tip 31 and tip 32 ......I also replaced the mosfets on the N and P channel boards......there was some 16gauge wire that I used to connect from the fe board to the N and P boards. They were too big and they really didn't fit properly. I used 20 gauge Teflon wire........the only thing I can think of is that I left the input cables disconnected when I attempted to set bias.Did you do anything else other than remove the diodes? You do have to go back to 0 and start the biasing procedure from scratch.
The difference between 346 and 336 is 3% and well within resistor tolerance, so it's nothing to worry about.
