That is surprising. The heater in most SETs should get the tubes to optimal temperature within about 10 minutes. I wonder if the heater isn't working right.
300B Warmup versus other tube or SS amps?
Anyone have experience in warming up their 300B SET amp? My push pull tube amp comes on duty after about 15-20 minutes or so of warmup. My 300B sounds distinctly better after 60-90 minutes of warmup. If it's on for several hours it may even marginally improve from there. It sounds a bit flat out of the gate (no warmup). My other amps are not as sensitive to this.
I am just curious to what folks have observed in there setups.
