It is the high stability one Chuck if it has the two adjustments and the 
doubler.  If you are planning on using it I recommend leaving it plugged 
in always and just pressing the Standby button when you don't want to 
use it which keeps the oven permanently on.  This way the oven will be 
most stable.  Mind you if you use the external timebase input there's no 
point in doing that.

Back in the day before T'bolts etc., it was the best oven I had, almost 
up to -hp- 10811 standards.
