Hi Peake,I got the 144 to work!
I made a really (em-bare-assing )mistake.For some reason,
(Beyond my comprehension), I added the second(+15volt) trace,to the
Matched pair(TI-122) Duuuuhhh! While that is in the ( CBS schematic),obviously you found that error,years' ago!Ha! I thought you were saying to add that?
(magical thinking,on my part)!!! I tried a (J175) and that works',but when I put in the (U147),
the square-wave got "really sweet"(5cps.-20Khtz)!Amazing (smooth,hollow)sound!
I have that position(socketed),so I will try several FETs' in there and let you and others' know what I find.I have found-out one thing; The matched pair need to be high-gain.While (low-hfe-170-250) may work,I used a set of (TIS-97s'),with an hfe in the (505-range)!!!! Possibly why the (U147) is working so well?So,I guess I will have to nix the (Terrence Thomas)generator,after all.Ha!
Thanks' for all of your help and good advice!
