RE: Music Reference RM9mkII Driver Tubes

If comfortable doing so, just use a soldering iron to reflow the existing socket pins where they contact the pcb board. Just smear a titch of flux using a toothpick on each contact should give you good results. Don't add more solder unless you really need to. Remove flux with flux remover if you have any on hand. Not too critical if you use it sparingly.

Doing a solder reflow should fix any broken connections.

Soldering done with amp off if course.

Clean and tighten the tube socket insert contacts too if you can.

Barring all the work above, you could always try wiggling the tubes in their sockets to see if the sound sputters back. But if it does, you'll end up doing the repair anyways. And sometimes wiggling isn't the best thing unless you've felt with situations like this before.

Cheers!
