Power Transformer Limitations - Page 2

One option would be to bias them towards the 'cold' end so the mains transformer only gets overloaded on occasional signal peaks. The issue is heat averaged over some seconds (or tens of seconds) not sudden death on overload.

power is not everything....I have amps that can run el-34's, 6550's, kt-90's, run them most of the time with el-34's which is a power cut (225 watts) from what they would give me with kt-90's (380 watts), but I like the sound better with el-34's. the mids and highs seem more detailed with el-34's.
