Update on JCM 800 cutting out

[Geeze]

I took it out of the cabinet, stuck some feet on it and plugged it in. Right away it started with intermittent sound. I jiggled the reverb wires [not plugged in] and voila! it has played for an hour now. New question - since I plan to build a head shell can I un-solder the reverb wires? Can I pull V4 or does it contribute more to the circuit than reverb?

I wouldn't pull any valves until I got a definitive answer. What model is it exactly?

It's a 4210.
