thus remove all heater loads from the FBT. |
I replaced a couple of hundred CTC16 flys back in the day, and I recall the big rush was in summer months when heat and humidity got to them. Most of the ones that failed were from arcing from the 3A3 socket to the core - humidity related.
I honestly don't know how much you will gain by using a SS rectifier to reduce heater loads. I would guess it's probably a half watt of heat saved overall.
Unless you're going to run this 8 hours a day from now on, and do so in hot humid weather, I really wouldn't worry about saving the heater load on the fly.
Tom pointed out a SS stick rectifier drop in replacement for the 3A3. Dad used one on our CTC9 and lasted for about 10 years before the tube went and we scrapped it. I believe International Rectifier made it.
