well alot of rf amplifiers use class AB for lower distortion and increased efisency but a tesla is harder to tune. I dont think that it is impausible but you need the right equpment like dual tunin caps ect. to tune

perhaps it may be easier to drive the tubes directlly using electonics ie half bridge and a oscilator with some zero crossing feedback insted of a armstrong oscilator setup. christensenda do you have any ideas

Am afraid my knowledge in vacuum tubes and oscillators is quite elementary, and solid state is non-existent. I was simply looking through some of the old threads and this seemed like an interesting idea and just wondered if anyone ever had any concrete results.

I don't know whether others who tried this experiment got frustrated or whether they had success it is definitely not for beginners. but personaly any thing can be done with enough persistance.

Well, last summer I built a single 811A. I would like to either build a larger VTTC or just build a staccato board for my existing one or an entirely new one. I havent built any complex PCBs before though. I figured that VTTCs' would be a small step towards solid state. Anything will be on hold for some time as seeing as I am currently studying abroad in Germany.
