Not knowing at the time a load was needed, I've accidentally not had speakers connected when biasing my tube amp, but that was quick (1-2 min) and thankfully, no damage occurred. I wouldn't do it again.
1st Tube amp question
I just purchased my 1st integrated tube amp, the Wilkenson R8. Can I turn it on with no source and no hookup to speakers to start burnin time? I have read it should always have a source and be hooked up to speakers so as not to damage. Can you offer advice for first time use?
