Well seems like radio is doing half power, thought one of the pa finals gone bad so pulled both and tested.. both test ok, before going farther going to ask for some help, the pre drivers look a little tougher to remove thanks

Would something like these work? I used them on a sb220 once but it was on the grid side..

Looks like they are getting hard to find

Next question would z-14 chokes work? I’ve seen them in macos and phantoms I’m sure theres others but personal seen those.. pretty sure 44uh

Doctor audio that’s the one ☝️....

This is a much larger choke then you would find in a Texas star... probably double the size

I have this to work off..

Can some please tell me what size this choke is? It looks familiar I’ve seen the same size in other sweep tube amps.

Just wanted to give a update, radio is WORKING!! Went through, performed tx alignment and found bad C714 trimmer shorted could get it to work off and on... had a few close to the correct size and adjusted and holy smoke she is alive... as always, thanks for all the help couldn’t do with out...

Yes I do have rx Ontario drew. And weak carrier and very quit audio on tx nothing on watt meter

Try this again on tx c0 b18.4 e0

Correction base on tx is around 18 volts

Yes I did replaced c314 with new part, forgot about the voltages, on rx c0, b15.3, e0 on tx base voltage goes up to 19.6 and 0 base and collector

Top of the morning, the transistor is a through hole so kinda hard to lift a leg, so went to the next step and tested c314 all is good. I did key the mic with the cap removed signal looks the same on sdr but transistor is not hot

Pulled relay cover cleaned relay and now have rx so don’t think the relay is the issue. But the driver is still getting hot when keyed up....
