I've heard you can damage a tube amp by running it without speakers attached. Is is ok to measure the voltages of my just-completed Stereomour without speakers attached?

Thanks,

Paul

An amp with lots of global negative feedback designed into the circuit can oscillate if it is not loaded by a speaker. Luckily this is not a problem with the Stereomour since it does not use global negative feedback.

Thanks for the quick response. I'll be plugging in this afternoon. Hopefully no smoke.
