...so i decided to retube this amp by myself. i bought a new pair of electro-harmonix EL34's, and a bias tester. i've read that for EL34's bias should be set between 27,5mA and 46,5mA. i've began with putting the tester under the first tube (the one nearest to the transformer) - i've set the bias to 36mA. after some time i've put the tester under the second power tube - the bias was "jumping" from 31mA to 34mA - so i set it up once again around 36mA. when i've put it back together and played it for few minutes i noticed that the tubes are glowing bright orange, and they produce in my opinion a lot of heat. should i back off the bias pot a bit? the amp sounds great but i'm worried about the heating problems and i don't want to change tubes again in two weeks or so;/ (sorry for my english
