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

I've worked on Scott amps and they're the easiest tube amps to use. Even with no restoration if the main filter caps do not show the signs of leakage, you may b OK to just turn on. As previously mentioned, use the load resistor at least if you're affraid to damage your speakers, but will less-likely be the case.
7189 Telefunkens are great choice for this unit. They bring a few more watts to the output power vs. EL84's.
