Snakes in my MK I RI!

[Pablomago]

Well, no actual snakes, but it's making a lot of background noise, hiss and high frequency stuff. It seems to be getting worse. I'm guessing preamp tubes, but what else should I check out? Would filter caps do that? Other then that it's sounding great and has no shortage of power.

preamp tubes first!

(and maybe wait until the lsd wears off) :lol:

It's OK, they're twineing around my guitar neck now. The patterns in the grain of my hardwood Boogie are especially far out! Wow! :lol:

LOBSTERS :shock:

You might have a Sonama County Cicada Locust in there. They usually get under the filter cap board. Make sure you discharge those caps before you go poking around looking for a locust...

Seriously, sounds like a preamp tube went microphonic as well as being hissy. On the MK I RI it's usually the V1 or V3 pre amp tube.

What 12AX7's are you guys using in your Boogies?

I pay the extra shekels for NOS G.E.'s, RCA's and Amperex's. Your amp and your ears will thank you...
