I have a marshall tsl 100, jcm 2000 and i think it needs new tubes. some of the signs ive noticed is that it randomly makes loud pop noises, resembling the sound if you were to unplug the cord from your guitar when the amp is on and you band it against metal. also some of the tubes were glowing a bright red. how do i know if i need to replace certain tubes or all of them. also, does this mean i have to replace the smaller tubes as well as the power tubes? thank you

mkay, you're tubes are ment to glow.

If one tube goes, you usualy need to replace the set as once tubes are worn in they're very difficult to match.

as for the popping sound, when does it happen?

right, i know when my amp is on and if i turn the fan off / lights then a slight pop is heard, quite loud with the fan though. So maybe something to do with the electrics? Unless my house is just really unsafe

i have the tsl 60

well, it's not supposed to make noises (i own a tsl60 too). if you don't know what shape your tubes are in, i'd just get a full retube. as a plus, mid-power 50-60 watt heads don't cost as much to retube

well a couple mins into playing it makes this noise that sounds like paper being rubbed against a phone and then it makes a bunch of popping. i looked on the back of the head and saw that the two tubes on the right were glowing orange everywhere inside the tube, not just in the middle. maybe this just means that the two write tubes are biased hotter than the left.

when i get the new tubes im also gonna need to bias it. i have a voltage meter but which do i set it to, DC or AC?
