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 agree with Kijanki. Also, the load needs to be within range of the spec'd load for the amp. That is if the output tap is suppose to be 8 ohms, you should connect speakers that are close to 8 ohms (+/- 50% is probably fine depending on the amp). If you want to connect a load resistor - it too needs to be the proper resistance - and should be adequate wattage. a 1/2 ohm resistor isn't enough - you need a 50 watt or so . . . depending on your amp.
