Guitar Combo Tube Rattle

MartinBlythe

I could do with some advice...long story short

I have recently re-housed my tube amp head into a custom 1x12 combo. 

Amp sounded fine with no rattle in the head + 2x12.....Now in the combo I have rattle. 

I have located it to one of the power tubes...BUT...the tube isn't bad? It only rattles when the chassis is inside the combo (screwed in). Tapping on the tube/tubes makes no difference and it sounds fantastic. When I hold the tube - looping the annoying rattle with my looper - it stops completely.

So my question is...what can I do to stop the rattle? Any ideas or advice would be greatly appreciate

Rubber O rings around the valve.

I used to use a single heavy duty rubber band per valve

It did cross my mind to give something like that ago. I will see if I can pick some up this week. Cheers
