Opened up new TR-4C that came from Flea Bay. I powered it up with the AC-4 that I put the Heath Shop P/S kit in and use daily with the 'B' line. Looks like only one of the finals lit up and some of the other tubes were not coming on and no sound at all. No smoke though. Pulled the cover off and gave a better inspection. Pretty clean, nothing burned and looks pretty good top and bottom. Tested ALL the tubes in the B&K 707 and ALL tested good. Ragged off the tubes to get a bit of dust off and wiggled them back into place. Put power back on and some of the tubes still did not light so started wiggling them some more and they started to come on. Now the USB/LSB lights are working but still no sound. Tried the headset jack and very good audio here. Sounds very nice indeed on 40M. Try the tune function and it puts out an easy 150+ watts. Mic jack has been changed to 1/4" and is not wired as std drake as in manual so I tested the PTT with a screwdriver and it clicks into Xmit OK. So have to get audio to the AC4 Jack (which worked on the other TR-4) and rewire the mic jack to test the Xmit audio. Both filters sound good and the PTO is nice and stable (although it feels dry). I found an old Turner 454 SSB to try on it.
