can power cable help cure static problem?

Klzdo -- the Lamm 2.2 is a hybrid amp containing a single tube, a specially selected 6922 triode, which is why I really doubt it's the tube. Still worth checking as I noted.

Gs5556 -- the Lamm 2.2 doesn't utilize tubes in the output stage. It's all-solid state, except for that single 6922.

It would be helpful if you'd describe the "static" in a little more detail -- like between stations on a tuner (white noise), or more of a snapping sound (electrical discharge) or hum/buzz (like transformer or motor EMI) Anyway, you stated:

"I switched around the mono amps and then the static came out of the other speaker so I know the problem is not the speakers."

OK. Did you leave all power cords, interconnects and speakers cables in their initial positions when you swapped the amps? If you did, and the static sound still follows one of the amps, then you'd have to suspect that it's the amp driving whichever speaker (L or R) has static coming out of it. Could be a loose connection in amp's manufacture that's picking up RFI. Frankly I'd be more suspicious of the amp if it were a tube amp. In fact you might want to try swapping just the two single tube in each amp, leaving the amps themselves in place. Sometimes tubes can be susceptable to RFI (from your TV) and though I kind of doubt that's the problem, you should rule it out. Also, don't forget that although it's a (less RFI-prone) SS amp, in the case of the Lamm, circuit ground and earth (chassis) ground are separate, so a bad tube or defective cable could be more noticeable.

All that said, if you DID leave all cabling in place and then the static DIDN'T follow the amp swap, then it's a faulty cable. Try swapping them, one type/pair at a time until the static follows one of the cable swaps.

If the problem were the TV (sending out unusually/illegally high RFI or digital hash) it seems to me you should be getting the "static" on both channels. Hope this helps.

Michael, one more time: the (single) tube in each of your amps is NOT an output tube. If you want to see if it could be one of these single tubes in one of the amps, then just leave the amps im place and swap the tubes. You'll know quick enough.

If it IS one of the tubes, then have Lamm send you TWO new ones, and keep the old good one for a spare. The tubes are not matched as far as I can tell, but you'd be better off with two the same age and from the same production run.

Michael, as I said earlier: if you leave the amps in place and swap the tubes and the noise follows (one of) the tubes, then it's the tube. Well it didn't, so you know BOTH tubes are OK. Now, if you swap the amps (L to R) and the noise follows (one of) the amps, then it's that amp -- which is what I guessed to begin with. It's NOT one of your other components.

There's either a bad electronic part or a bad connection in that one amp. Have the dealer send it back to Lamm for repair or replacement -- in fact with equipment of that caliber, I'd insist the dealer send BOTH amps back for a complete inspection. I say that because the problem could very well be that one of Lamm's OEM suppliers provided a batch of defective parts, and Lamm might want to replace a few parts in BOTH amps, so you might as well get it taken care of once and for all. Trust me, I've been through this exact same scenario with ARC, Levinson, Martin Logan. It happens a lot, unfortunately. And if you send in just one amp, than as soon as you get it back, the other one will crap out! It's a COSMIC RULE! Also, remember to ask for an extension of your original warranty period.
