Hey, my amp seems to be getting quieter, could this be a problem with the tubes?

Im pretty useless when it comes to electronics

Thanks in advance

It seems to have less low end to it, like when you play Battery by Metallica, it doesnt have to nice chug sound like it used to
Is there anyway in checking?

Just open up the back panel and take a look in.

I was wondering why I had a rather sudden loss of tone and reverb quality, so I had a check and 2 of my bloody preamp tubes were dead.

Sounds like bad tubes are the culprit! Have you ever changed them before? Or know how long it has been since they were last changed?

I havent changed them before, and the amp was brand new from a shop last year, where it was hardly used so Im gonna take a picture of the Tubes while the amp is on, and they're Ruby 6LG or something like that.

As i said, im crap with electronics and knowing my luck, id electricute myself haha.

I could get my dad to have a look at it when he gets back.

EDIT: I cant get a decent picture of them, but one of them seems duller at the top of the tubes than all the others, if that helps?
None of them are glowing blue either.

EDIT2: Its gone muddy too, with and without the BBE pedal

If its a year old and youve never changed them before, change them all. Take it to a local tech if there is one, or do it yourself, its really easy!

any idea's to what tubes to put in then?
Its starting to hum like ive got single coils when im using humbuckers

EDIT: Now i have to turn it up to number 3 to get to sound like it used to on number 1.

Just changed all the batteries, sounds the same

Just sorted one of the problems out, my cousin had messed with the amp and plugged the effects output into the preamp output like the idiot he is, that brings the volume back to normal, but theres still something abit iffy.

How often do you play, and how loud? If this si your 6505 we're talking about...honestly doubt you need to retube. Are they getting worn some by now, yes, but they still probably have good life in them yet.

Just trying to save you $$, retubeing a head like that will probably be at least $100.

Hrm, then I guess you should consider it. General rule with everyday use is powertubes every year and preamp tubes every 2 years in a head. (1 and 1 in a combo, as combo = more abuse)
