QQ: Anyone Bias an Engl Savage before? Does anyone know what's up with the cold biasing. I noticed the bias quite cold and the range is limited on the bias pot when I went to change out my 6550's to KT88's last night. I did some research, and looks like this is by design not only on the Savage but several other Engl model amps too, but wondering if there is a recommended percentage ENGL suggests, since you clearly can't bias up to 70% Are most people having to do resistor mods in their Engls or using some sort of standard percentage to bias their power tubes running them a bit cold all the time? I went ahead and set them for 50% for now, which is a bit hotter than was default. It seemed like the amps bias pot was all the way down to the minimum or very close. This is a brand new old stock Savage I picked up, so it's never had tubes changed. I just wanted to throw in some KT88s instead of the 6550 Engl Sovteks, which I prefer a bit more.
