I like the way you think! Very cool!

Thanks to you all. This site is a treasure.

Bias problem corrected. Thank you Andy. I am new and Learning. I need to reed more. I am currently reading everything Lou Franklin had to sell. Andy do you have any good recommendations on books to read?

Thank you for your time and great explanation Andy. I will let you know how it goes. Out of time today. This makes sense and I was thinking I needed to reduce the bias voltage, I just didn't know how.

What’s your armchair diagnosis if it’s not converted?

Nothing is shorted. The driver transistor checks good out of the radio. It’s probably something really dumb.

The driver current is 10.45 amps yes 10.45 whole amps. The finals combined current is 100ma.

I will measure the current and post it later today. Sorry!

The radio has been upgraded to mosfet’s,They are legit bought from Mouser. Problem is I assumed the driver and finals were bad, my mistake. The Bias for the finals is perfect 3.6 volts the driver will only adjust from 8.4 to 8.3 volts. The pot is 100k. And has been replaced and double checked.

This radio does RX and transmit and has audio but the power is less than a watt. Driver bias is very high 8.31 - 8.48 volts and won't adjust beyond these numbers. The VR 11, driver, Finals, Zeners, pre driver, IC 4, Audio Amp TR51, Have been replaced. I have voltage tested every Transistor and...
