hey guys,
this is my first post as a new user, so im just going to dive right in

i recently aquired a Hartke GT60 "piggyback" half/mini stack.
i know is more of a budget style amp, but i only paid £80 for the whole thing, plus £10 on a better speaker cable, so if it dosent work out then its not a massive loss.

the guy i got it from says its only a year old, but i am aware that Hartke disscontinued this amp last year(?) correct me if im wrong

first impressions are good, but as i have never owned an amp with tubes in it i am unaware of any checks/maintenence issues that may arise. i understand that it has a single 12AX7 pre-amp tube, then solid state power amp section.
will a change of tube get me a better quality of tone and gain? as the tube that is in it is a cheep russian job.
what tube would be the best one to go for? as there is so many and im clueless!

any help, advice would be great,
cheers

You probably wont notice much if any tone diffrence if you change the 12a7. Most amps with a single pre-amp tube are gimmicks to get you to buy the "tube" sound.

ok, so the best thing to do would be to let the tube go untill it needs replaced?

pretty much. If you want to try, 12ax7's are fairly cheap and its good to have a few spares around just incase.
