My test speaker is an eight ohm driver. Super Reverb OT wants to see a two ohm load. Would it be a mistake to present an eight ohm load to the OT for test purposes? My work room is pretty small. cheers Roly
It’s definitely not ideal. This scenario will put a lot of stress on the power tubes screen grids at high power levels, and makes it easy to heavily overdrive the power amp, which can cause that expensive magic smoke to appear if something is a bit ropey. It won’t cause a problem as long as you don’t try to push high power levels out of it. Being in a small room should kinda make that a necessity! Certainly don’t attempt a full power test, or at least not more than momentarily.

I have a stock 67 super reverb and I’m always careful with connecting it to the proper load. With high end Solid state like McIntosh amplifiers it will take the mismatch. It also has protection to shut itself down if it gets too hot. My recommendation is don’t do it.
