Thordarson, during it's merge with both Halldorson and Meissner, often repackaged the other's flys and yokes, placing a gold or green part number label on them to denote they didn't produce the part. Once the merge was complete, and all stock depleted, Thordarson parts (pink/red label) were 100% theirs, and I've never seen one go bad. The only 'bad" ones I've seen were new ones with broken ferrites - shipping casualties.

We had a CTC38 that cherried the 6JE6 - it got the tube so hot it sucked in the side, but the flyback (a Thordarson Fly) was good, proven after sweep tube replacements - as mentioned earlier - the oscillator, damper, output and HV rectifier, and a retouch of the efficiency coil.

Triad D-310's (CTC39 chassis) were also rock solid. We preferred them based solely on price, about 6 bucks cheaper in the late 70's/early 80s than a FLY312. RCA 119834's changed drawing numbers somewhere in the 70s, but the design was still the humidity-will-surely-kill-it design from the early 60s. Thordarson and Triad encapsulated their flybacks in RTV or epoxy, and they tended to run a touch warmer than the RCA flys because of this, but they held up just fine. My used-but-good FLY312 came from a gunshot set (we recovered the .32 slug from the CRT), and I got the chassis and convergence board. Now to find a set....CL here is full of BPC "vintage" sets.
