I was given a vintage Branson brand Power Control. Thinking it might be of use in powering up vintage tube electronics, I accepted. I have attached some photos, and have some questions. It is a 240v input unit with 0-240v output.
Is this the same as a "variac"?
Can it be used with 120v input to get 0-120v?
The % output meter does not work. Any hints on a repair of this?
Any other potential uses for tube audio newbie/amateur?
Thanks in advance, David.
