There are a few things other than output transistor failure that will make a radio fail to transmit.

Try listening with a nearby radio first. Check the receive and check the pll for lock. If the PA and the receiver work , if it has voltage to the final and can be heard by a near by receiver...

Yes , the above modifications will work for the 3-5821a. If you're up against a steep learning curve just let us know.

To get started post the board #
"PTBM***AOX or COX . It will help get the correct schematic.
