Possibly @Pez might know the answer Or possibly contact Ken at Anytone, he has been helpful to me in the past. When the CRT 9900v4 first came out with 12 meters we were trying to get the quad 6 to go down there and Ken is the one who told me there were hardware changes to the board in the CRT...

Yes Ask the Chat bot a question Tell it that it's wrong It will thank you and rewrite the new answer for the next person Wrong or not And the cycle repeats 73 Jeff

What are we trying to do? 73 Jeff

It's a CB amp, and in that sense they're all garbage amps, however it's still better than some of the class C stuff that seems built to include the least amount of parts and still make RF. Cb amps are not Henry or Metron built quality..... 73 Jeff

Looks familiar.

Steve is building again, and doing work for Henry radio as well, he is very busy. 73 Jeff

Good to see you Roger. 73 Jeff

Mike, very few builders in the US use temp tracking electronic regulated bias, off hand I can think of one person that does this on 11 meter amps that does it well, and it's not cheap. It's just how it is unfortunately. 73 Jeff

I Agree I have a TS 500 that has lived a very long life, I run it at 350/360 watts out and I get compliments on the audio on the air. Seems to be the sweet spot for 4 Toshiba transistors. 73 Jeff

When they added bias,then, well, It's biased, and that means it's no longer class C. Anyway that's good for SSB. 73 Jeff

Actually Carl does build biased amps, you just have to check the box for it at the time of purchase. And I do agree You should run bias for SSB if you want to keep it clean.. With those radios I don't think you need a driver transistor, but I never liked amps with built in drivers anyway 73 Jeff

Those old Palomar TX-100 amps were really popular in the late 70's 73 Jeff
