Threshold SA4/e bias

[nchelazzi]

Hi, I bought used a Threshold SA4/e but I noticed that it run colder compared to other models that I own. I suspect that I should adjust the bias but I don't know the exact value, nor I have a schematic manual.
Anybody can help me?
Thank you in advance.

Niccolo,

Exact value of the bias is heat sinks at 50 deg C - good for a
5-10 second touch.
