Best to power it up on a variac. Mine did produce a vertically shrunken color picture on all original caps for a while, but bad lytics drawing too much current caused the 3DG4s to short and a panic shutdown not long after...These are getting to the age where new lytics are mandatory, and recapping the sweep is good practice,

There are enough Black Beauties in the chassis to be really scary. I have replaced hundreds of them in my radios, and they were all leaky to some extent. Beats me why the audiophools pay big bux for them, sigh. In any case, BB and electrolytic replacement is in order. Just have to clear the bench, that is a LARGE chassis!

Actually, I believe it's guitar people who love "Black Beauties"...something about tone. Dunno...as an audiophile myself I don't want any of those leaky buggers around.

At least there is money to be made taking the bees we'd normally round file and selling them to the guitar people.
