Re: NR compander (P-522)
I agree with John that tricks are best performed elsewhere. ;) Alright then, I shall resist. LOL John, I remember you mentioned that bootstrapping trick once, and I stored it away in my noggin for possible later use. I'm more of a cookbook guy than a textbook guy, but examples of stuff like that ar...

Ah, I forgot about that effect - a plus maybe for keeping the cap there. Too bad it has to be so large...

Re: Another reason not to buy used appliances from Crusty...
Not too hard S.S. - a good thing cuz I had to drill/tap a 2-56 hole into the side. It was absolutely perfect diameter and had the 'D' cut I needed on one end already, so it was meant to be. Weird how that works out sometimes. It was a simple plastic shaft that broke - the plastic got all "chalk...

Another reason not to buy used appliances from Crusty...
No beer bottle used this time though - I ended up fixing my dishwasher with the metal shaft from a male Elco connector - I'm not paying $200 bucks for a soap dispenser! I just need to explain to the wife how it operates a little differently now...LOL

Hum differences in toroidal power transformers...
Observations and not a scientific experiment by any means but... I had, on-hand, three different brands (two or three of each brand) of stock toroidal transformers from Amveco, Avel-Lindberg, and Multicomp. All were15V 50W ratings. I swapped them into a PSU connected to a circuit pulling about 25W. ...

Re: An Improved Servo for the THAT1510 and THAT1512
Hi Wayne,
Wondering a bit more about the tempco - Did you disable the Vos buffer as well as the servo when you did your temp experiments? How many 1510's samples did you try?

Re: NR compander (P-522)
I got to play with this a little this weekend by scabbing into an eq. Not really needed as the opamp I used recovers quite nicely on its own. It does make for a nice effect when abused (!) I 'nested' a few sets across the feedback path and could get a nice and smooth limiting effect. I want to try s...

Hey, nice work Wayne! You do need to spill the beans on your coupling cap experiments too. LOL
No worries about tempurature drift? The switch you characterized is a break-before-make?

Re: NR compander (P-522)
Sounds like it will be a snap to assemble once the case design is worked out and you lose all that secondary machining. I think the "half or list price" must have been for the existing product line we were talking about. This guy shut down his factory and moved production to a contract man...
