Had this exact same problem with a Jupiter-8 that I had in for repair.

Tuning wouldn't stabilise. Fitted standard, boring 12V computer fans (2) at

rear vents to get air circulating around the boards. Voila - no more tuning

problems! It wasn't an issue powering them of the Jupe's internal 12V, as

the fans were just small low-power ones.

Stick 'em onto the vent holes at the back ....
