Is the tone generator in the rt2 the same as the one in the e112 or a100 and others?

The normal voltages from the TG are pretty low, like six to ten milivolts (.006 volts) Handheld multimeters are not all alike and some do a poor job with signals this low and with frequencies that a TG produces. What meter do you have?Tom in Tulsa

hi ! i have a canadian tire brand multimeter made in china , it supposed to be auto ranging with ac and dc , when i set it on ac voltage i attach one lead to ground and the positive lead at each end of the coils on the tone generator , on some i get a reading of .002 volts and some no reading .
this is after i have replaced all of the caps , i should be getting readings in the .006 range volt readings , should i not !

Possibly the same as in your A-100, depending on the year of the RT-2. On the -2 series, the tone generator output terminals may or may not be in chromatic order depending on when it was made. If yours does not have them in chromatic order - then the A-100 generator will fit.Current organs: AV, BC, A-100
Current Leslies: 22H, 142, 147, 760
Organs in the past: L-100 (several), M-100 (x2), T-100, E-100, CV
Other keyboards: Roland FP-4, Yamaha DX7, Yamaha TX81Z, Yamaha Motif ES Rack, Korg Krome, Novation Mininova

A problem with the e100 unit will be that it does not have the lowest octave of wheels, tones 1-12. In the e100 these tones are provided by a divider in the pedal circutry. I've redone four tgs and three of the four sounded fine and didn't require adjustment, at least for my ears 8) I would bet lunch that your meter is just not sensitive and accurate enough to give you useful readings. How does the organ actually sound? I would expect a dramatic improvement (unless like on my BC some 'tech' had done "bad things" to the preamp)Tom in Tulsa
