Its been a lonng time since I posted here last, anyways I have an old rca tube TV. More specifically an rca truflat crt. I started it up today and it displayed static and warmed up like normal but then it shut off and started making a chirping noise. Almost sound like the flyback is trying to...
I have returned lol. Anyways I've been wanting to build myself a vacuum tube tesla coil, more specifically a high frequency vttc kinda like the on that the youtube styropyro built. I came across these two 100TH like vacuum tubes with a maximum power dissipation of about 250 watts at 3000 volts...
I only have a one-phase mercury rectifier. I think it's an ignitron type with a filament so it wouldn't need a reignition voltage if I just keep the heater filament on, right?
Thanks. Mist of that schematic looks pretty similar to my radio but there is also definitely a c+/c- voltage terminal. (Completely separate from the 22 volt terminal)
It's about that time of year where my parts cabinet is overflowing with junk again, and I want to make another tesla coil with the stuff I have on hand. I already have the coil and matching caps and the transformer but I don't have any diodes.(I do have a surplus of mercury arc rectifiers...
I acquired a fada neutrodyne 175 a battery powered tube set at a flea market and noticed that it has three tuning dials. Got a few questions. How do you tune this set? Whats the easiest way to power this thing? (I know it needs all three voltages a,b,c.) Never worked on battery powered tube...
How is my entire premise wrong exactly? I have a bunch of old parts and I like to build stuff the old fashioned way even if it isn't the most efficient way of doing things. I also wanted to use a neon bulb because I have a bunch of them and I think it kinda looks cool.
I'm aware I could just make a neon oscillator without the relay but I was hoping to use a dual switch relay to switch a slightly bigger load than what the neon circuit alone could handle
