I used to have a Metal Monster and swapped the Sovtek to a EH. Not much difference to my ears.
so in your opinion its not worth changing tubes? cos one tube is abt 16 bucks too. not as cheap as i would wan it lol. but still old tubes needs to be changed right?
Yup, change em only if they are not working or noisy (which is unlikely due to low power) and there may be differances but pretty much insignificant unless that tube is overdriven.
Even in a clean amp the above may be applied for preamp tubes.
Just the opposite for a cranked or a high gain amp tho, the pre amp tube & phase inverter type, needs that much required attention.
Btw ...save your pocket money and get a real tube amp :mrgreen:
here is a little secret on tubes.
