[sdiy] ( Sort of) Ovens for oscillators?

[Hcabnivek at aol.com]

On a similar subject...  
I'm building a normalized synth with about 6 ocs's of the Electronotes/ASM-1 
variety and I'm wondering,  does it make any sense to set all of the 
mat-02/tempco combinations into a single block of Aluminium and/or put them 
in a vacuum bottle.  I'm hoping that I can get all of these to reliable track 
(which may be nuts) and I want to do everything I can to keep this thing in 
tune.  If there is any benifit to the vacuum bottle idea then should I put 
all 6 osc's in or can I get away with putting just the 6 expo's in.  I've 
never heard much about the temp. stability of various osc. cores, but it 
seems like it might be important as you add osc's.
Any opinions?
