It was done with a gen that has "B" or "B1" hand written on the label. I don't think yours is one of those.
I'll make one like yours and run some batches to check it out and send a sample to Frank. PS All the "Ole Bob" gens were mechanical stir. I no longer make those. I did make a few Ole Bobs with looped electrodes. Here's the progression and differences in the Series 2 models [Looped electrodes/ thermal stir] GTS2 original...used 2 pole phono plug input type transformer. [6.2 volts at off trigger]. GTS2A .....changed to barrel type plug on transformer [that's all] GTS2B and B1....current model...feedback circuit changed to virtually eliminate semiconductor leakage after auto off triggers. [It was very low before, now so close to nil it's almost unmeasurable] Effective voltage reference is .06 volts lower than previous giving a slightly higher conductance reading at shutdown. [about 4 uS?..that is a guess as PWT calibration nightmares have been going on too] Test bench shows a change of -55 to -100 ohms resistance [the inverse of conductance] from previous version with typical variences in current output at .98 ma to 1.05 ma making the differences between generators using componants rated at 1%. [volts, ohms and amps are all interrelated].
