Tube amps and loads.

My search may have not contained correct phrasing for an answer.
So to you guys;

I have a Scott 299 & 299b. Both restored about 1 1/2 years ago. Unfortunately circumstances have precluded playing with them.
I asked one of our esteemed audio nuts if they needed to be brought up on a variac, answer was no although if I were more comfortable it wouldn't hurt.

Question; if I did use a variac do they need speakers hooked up, or a resistor of some type.

I have read here if amps are powered with no signal a load is unnecessary.
And others have said load is necessary.
Please help.

Best,
Dave

Normally Scott amplifier design was pretty forgiving and no load was required. I would not go with that now. If the controls are clean there are probably no worries, but if there is a problem and your output transformer pays the price, then a load to prevent arcing would have seemed like a good idea.

However if its got new caps I would just plug it in with speakers and see how it goes. You might need to run it a day or so before you take it seriously!
