its a shared "delusion"

Yes, I had though of that. I think, though, that I would be just as guilty of a crime doing that as I would be taking the tubes out of an early Tek scope to make an guitar amp. I think that if I got

This is not for filtering. The L manual says: "Low-frequency peaking for the X10 amplifier is provided mainly by C6002A and C6002B in the plate circuits of V5942 and V6042. With their associated

I have an invaluable book from Fairchild, published 1973. “The TTL Application Hanbook”. I checked your need, and what I can see, the only thing you need is a divide by 10 counter. The 8292 is

Looking for GAP/R (Philbrick) amplifiers might help. Some of those were chopper-stabilized and used IIRC Airpax choppers. Cheers, Kuba

Hadn't we all :) That's like with some "advanced" and "seemingly complex" ultra-low-current measurement. If you look for it on-line, there's a Bob Pease EDN article where he explains how he measured

Well, it's an abstract concept, I guess it's better treated like one. Your only "idea" should be of the properties of this number, and some applications that suit your interests. I don't think I have

I have both a 492 and a 494P and both run quite hot (measured with my finger). I did not put a thermometer on it, but 56 degrees C sounds about right, I can lightly touch it but would not want to

The 8292A is a low power presettable decade counter that can be connected as a /2 or /5 counter. In the biquinary mode, it is a /5 followed by a /2, and produces a square wave. The outputs can be set

Just need to remember ELI the ICE man. This is the way I learned it in the early 70s. See http://hyperphysics.phy-astr.gsu.edu/hbase/electric/phase.html#c3. I think you have it reversed. Russ WQ3X

does anyone have any 30 pin or even 15 pin hp card extenders?? also extenders for the cards "inside of 7000 series plug ins"

maybe dean kidd has one

The 156-0091-00 was replaced by 156-0727-01 in all it's appearances. No reference to any parts repl or mod kits so it should be a direct replacement. According to the databook 156-0727-01 is either:

Hi Andy, I have sent you the 21A/22A manual extract off list. I'm not sure what you mean by the big honking filter cap in the L. It certainly has quite comprehensive decoupling of the B+ to the low

Hi all, I felt the rear if my Spectrum Analyser 492BP. I can not touch the metal strip just above the plastic cover it's that hot. So I got out my Fluke IR Thermometer and the surface read 56 Degrees

Only thing I could find was a reference to it as a decade counter. Perhaps someone on the list with an old Signetics logic book could confirm the details (IOW why it was chosen compared with 74xx

Need several LED displays for my DC508a counter, part number 150-1025-00 or the entire display board number 670-5101-00 Chris

is Actually tried that recently when I was bored... took a small print relay (not really miniature, probably a reed type internally.) What I got was around 10kHZ - don't know how long it will survive
