Squeaking/Paper Crinkling Noise Coming from Lamm LL2.1

Can someone suggest what the problem may be? Hearing noises in quiet passages and with no source playing through my Lamm LL2.1.

Noises are equal in both channels. I've swapped out all the tubes. Replaced the cables. Still happening. Doesn't change with volume level.

Ugh. Lamm is so bad with repairs.

Also, there's no way if I replaced all the tubes even with less low noise tubes, the exact same sound would be coming out. Something would change. No other tubes. Just Herron M1A monos. Can it be some other electronic component like a capacitor?

Replaced all the tubes and the sound was exactly the same, so that's not the problem. The amps are solid state but the sound goes away when the Lamm is muted or off so it's not related to the amps.

Not really available and if you send it in for repair (because there are no authorized service people as far as I've been able tell) it take 2-3 months.

It caused the sound when it wasn’t even connected to the Lamm. Selling that streamer right now.
