Hey everyone!
So I was looking around for some cool tubes and this baby caught my attention.
The seller doesn't know much about the tube and stuff and he has provided only 2 images. He says in the description that it's off a military thingy and it works on the HV side.
Just by looking at the pics, I can see the letters "ТМИ-9" which is basically "TMI-9". I can't really see the other number(s) and was wondering if people who are into Russian tubes know anything about this.
Obviously, searching for "TМИ-92", "ТМИ-90" or "ТИИ-98" doesn't yield any results.
The images have been attached below.

Damn, thanks. I must've read the letter wrong. *facepalm*

Do you think it's worth it for DIY tesla coils and stuff? It's priced for around $35. Might be able to get it for a bit cheaper.

Hard to say without plate curves. It's a beefy tube that has been designed for radar pulse modulation applications, running at supply voltaes of several kilovolts. How many kV's do you want to feed into your Tesla coil?
Best regards!
Best regards!
Hey! Not too sure, but maybe 10-20kV @ 2mA or something. Can't really do more than 50W or so at a few kV, but I can do an Amp at 300-400V.
I've already attempted to make a tesla coil with a TM-85 Chinese pulsed radar tube with similar specs to this GMI-90 and I got 1cm sparks out of a 6cm tall, 1.5cm wide secondary coil at 200V @ 0.3A or so. The limit was my PSU and bad tuning of the circuit LOL.

Perhaps you could use a pair of microwave 5KV transformers for these, left channel & right channel? This may not work as these transformers are noisy, a fully audible loud humming sound...your noise-floor would be rather high.
All HV protocols are in effect here right?

I might do that. Even though it sounds crazy putting 4kW into a tesla coil, it'd be cool.
Of course I will be. I have lots of experience with HV and many safety equipment which will be used during these experiments.
