Using a Variac on a SS amp, you better know what your doing. MOST SS amps Don't like low voltage. The reason for a Variac in older gear is just as Mr Bourne said, BUT there is a big difference in the HOW old PtoP come online vs SS. There are diodes that just DON'T work until you hit that 105-125 vac mark. It will COOK the thing with low voltage..
I take up to a week to bring up an old point to point amp. 25 vac for a few days. It tightens the old caps up and can SLOW external liquid leaks on the PIO and even filter caps..
OP how are the surrounds and cabinets? Are all the servo amps an XOs there?
Betas can be a lot of fun.. I've tinkered with them a few times, added enclosures to the mids and low mid planars. Just stunning after a few mods..
Stock.. What can I say they are OB dipoles, tough to get them to work right, a LOT of combing going on. The timing front to rear with that narrow baffle????? They envelope a room stock. A lot of sound everywhere!!
The Servo bass CAN sure work great too..
What state are you in? Not a trick question either. :-)
