[sdiy] ARP Odyssey tempcos was: tempco contact

[Nicholas Gregorich]

All this talk about the best place to mount a tempco on the actual 
package of the transistors, and my ARP Odyssey's tempcos aren't even 
touching the 'matched' pair! There's at least 3mm of clearance between 
the two.

Odysseys don't have a reputation of being drifty, do they?

Nick.
