Locked Re: HT-37 transformer failure due to rapid STBY-->OFF-->STBY
¿ªÔÆÌåÓýRick and jim ?Re You are most likely correct, if the power transformer is still good after some 60 odd years, it may not fail, at least in that manner.?? How many ways do you think there are to smoke the HT-37 transformer? Just one? ? I am a professional knob-speed-twisting-tester and can prove you wrong--- on your rig. The original owners read the bible before plugging it in,? but then some others don¡¯t, just plug¡¯er in, turn the knobs and find out what happens.. that is what they are there for!!? ¡.

Rick You are most likely correct, if the power transformer is still good after some 60 odd years, it may not fail, at least in that manner.?? ? Are the two 5 volt windings side by side on the same top layer?? If this is the case then I can see your corona effect between the high voltage winding closest to the core and it's associated 5 volt filament winding on the top most layer.? This would put perhaps more then a KV difference between one 5 volt winding and the second HV winding sitting just below it.? I didn't see this possibility till now; not having seen the actual transformer and how it is wound.? Is all of the insulation between layers paper or Mylar? Regards, Jim
