Re: HT / filament transformers from Aliexpress
Yes I'm rather excited about this. If they aren't total rubbish, it opens a whole world of possibilities. I have two dead end projects which this may kick into action as well: VTVM and oscilloscope. Both are currently shot down awaiting suitable HT transformers. Not sure they have enough grunt to drive the VCR139A tube I have (with voltage tripler) but may be.
