Hi i have an Ultra 60 and a ValveKing 212, and i want to use the Preamp of the Ultra 60 to the Power of the ValveKing / and its speakers. Is that dangerous? do i need to keep speakers plugged into the Ultra 60 even tho im not using the power section?
Yes, the Ultra is a tube amp, right? Even if you run the preamp send to the VK, you need to keep a load on the Ultra's speaker outputs, otherwise you'll blow the tranny. And it's never good when you blow a tranny.
