Not cost effective at nearly $10,000! I understand they're very rare, given they were only used for a few years in industry and they're clocking on 3/4 of a century old, but even then, that seems an order of magnitude or two off the real value. Actually, looking them up, doesn't seem they wer

It would be a lot easier to replace the large circular regulator if you're taking the shotgun approach, and much more likely that the regulator is a source of faults. and it's cheaper. For the h744, 45, 54. BUT measuring things is the best way if you can do it. Pull the values from the backpla
