Can't imagine what it does or why it's configured like that.
Coils must be somewhere below 40
Looks like an RF deck but 4 decks on 1 chassis?

Not 100% sure but I think it is used to basically vaporize metal to deposit on things. Machinists use them to build up worn out parts before machining them back to tolerances.

Says "sputter" power supply. The RF output feeds to a low-pressure chamber where the RF vaporizes metal to coat the surface of a workpiece. Pretty sure this is how the metal layer in a music CD is applied. The mirror-type "aviator" sunglasses are made this way, or at least used to be.

I would guess that solid-state sources of RF power are used these days. But it is in fact four amplifiers. The pics show four inputs and four outputs.

But no source of 3500 Volts DC to run it.

Thanks for solving that mystery but used to vaporize metal the tubes must take a beating. So much for parts value. I see that Seller dripped the price by half.

Took a closer look at the first pic. The elapsed-time indicator reads 45,490 hours. Sounds like a lotta mileage.

The question is then, are they highway miles or city miles?

With 4 separate rf decks, this thing is screaming for some kind of four antenna array.
