Moog Model 10 Tuning and Warm Up Time

[PaulLawler]

I was thinking about this earlier today. It is very possible that some of your tuning issues are due to temperature fluctuations.

In 79, I was crazy enough to use the IIP on stage at the Troubadour in LA. Every time a spotlight was on me, it also hit the Moog and the tuning when to s*&t. Last time I used it live…

I have the backs off both my vintage P Cabinets. (Never actually had them…) They are about 6 inches from a wall, but that wall has been covered in acoustic foam (which is a great insulator). With the backs off, there is no heat buildup. Once the room heats up in the morning, the temp is pretty stable throughout the day. My system stabilizes pretty well in about an hour and stays that way until I shut it off.

Yeah I think I should try taking off the back , hoping not to damage the lovely tolex in the process though.

I made natty little thermal jackets out of thick packing foam for the relevant transistors in the 901a/b ‘s
Seems to help and worth it for the sound of the 901b’s.
Takes an hour and costs nothing.

Have you got any photos of them, and where you put them etc ?
