Thanks to all of you. It's very helpful for me :-).
Yes, I also didn't notice any significant difference between different T model organs regarding the vibrato drive and, most important, recovery circuitry. And yes, the T serries delay line is shorter compared with the ones found in big (five octave) consoles).
The scanner Bob mentioned was a 32 pole one in early H series organs. Maybe it's the Celeste scanner?
Btw, you may have been asking yourself why I'm asking such a weird question. Well, currently there's a R-100 organ offer here for next to no money. I'm tinkering with substituting my C-2's original TWG with that one that has real sinusoidal tones at #1 to #12 and rewire the manuals to have real 16' tones at the lowest octaves. I'd need to add either the drum scanner or the pan scanner fo one of my T's to that generator to keep the vibrato/chorus...
Best regards!
