Can anyone tell me if there is a way to adjust the B200 thermostat that is on a #61 that I just picked up? When I plugged it in yesterday it started to warm up but then stopped . So I removed the thermostat and wired in directly to the heating coil and after being plugged in for 20 minutes there was 1/2 pot of lead melted. I left it plugged in yesterday for an hour and a half and the same lead would not melt with the knob turned all the way up. I am leaning toward ordering a replacement from http://orders.ppe.com/odr/rbpperetail.htm?p-part=B-200, it appears to be identical to what I pulled out. I seem to recall reading in one of the threads about an adjustment being made on the shaft but I haven't been able to find that thread. Any help would be appreciated .
