Safe way to change cables with tube amp on...


Couldn't figure out a way to phrase my question so here's the longer version.
I have an older ARC D250 amp and was told that one shouldn't remove the speaker cables with the amp on. Is there a way to acomplish this as I hate to power down the amp when trying different cable combinations.
Would a resistor across another set of taps work on the amp?

If I were you I wouldn't try it. Too many times a tiny error has ended up in a blown amp. It's better to just power it down. One tiny mistake and you'll wish you never thought of leaving it on.
I would strongly second Warner's caution above. You shouldn't leave a tube amp without a load and using a resistor across the taps is very prone to mistakes -- remember a resistor would have to be connected to the live taps!!
Go ahead - try it! No guts, no glory...

But, before you do anything like that, make sure you have already ordered your new amp. 'Nuff said.
