[sdiy] thermistor question

[Jason Proctor]

hey Tim,

thanks for the response.

yeah i think the SDT-1000 thing is a Roland designation, but i just 
wondered whether the 1000 might be significant somehow. i'm probably 
confusing thermistors with tempcos.

it's not critical, it's just the 1v/oct stabiliser thing :-)
