[R-390] VFO Heater Questions

[Perry Sandeen]

GM List,

I read an article in ER magazine on the Collins VFO and learned it had an adjustable thermostat.

1.  Does anyone know what is the nominal temperature setting as well as the high and low limits?

2.  Does anyone know what is the nominal current draw of the VFO heater.
 
3. Although the Y2K-R3 BFO schematic shows no heater, is that correct?

Regards,
