I was looking for a low-power tube amp to have fun with at home and to record with. I found a used SVT-2 Pro quite a bit cheaper than the PF-50T I was initially considering. Most tube amps can run with just one pair of power tubes. Ampeg Japan told the dealer that the SVT-2 Pro can do this but only for short periods. Anyone know why it's not recommended? Or anyone think the dealer or the importer may simply have given a mistaken answer? My main goal would be to have less expense replacing tubes. I'd also save a little on electricity and it'd generate less heat I believe.
