Metallic Chime noise Marshall Origin 50

[TONOHONEY]

My Marshall Origin 50 combo amp started making a slight metallic chime noise when I strike lower strings fretted and unfretted. I’ve tried with more than one guitar, no pedals and multiple chords. It’s the amp. Any ideas? It’s not easy to check tubes on the Origin amps

Sounds like output tube to me but I'm no tech.

I'm thinking a microphonic preamp tube.

Probably a microphonic pre amp tube.

Change them out 1 at a time to find the offender.

Sound advice above, tube rattle/microphonic.

That's one of the reasons I only have heads.

My Marshalls seem vibrate the Hell out of the guts when it comes to combos.

Imagine that, a Marshall so loud and thundering that it would wiggle a tube, or component loose. Lol

This was my first thought.

Mine was also doing that, figured it was the fretting on my guitar, changed to another and it stopped.
Did you found out what it was?

Same here. I took the chassis out and the problem was solved temporarily. I figured it was the first preamp tube (V1) and I replaced it with another I already had. Problem solved at no cost and only the least inconvenience. Great amp, well made for a great price.
