They aren't in the catalog but you can find them if you go to http://www.digikey.com/ and search for "carbon composition". But you'll find they cost $2 each, when they have them in stock! I HIGHLY recommend that you consider metal or carbon film instead. No, they don't look the same as the originals. Tim.

Film resistors do not handle pulsed power very well, but >carbon composition does. That's just a matter of proper derating, though. And, of course, finding failed film capacitors can be difficult, while detecting failed carbon composition resistors can sometimes be done from the other side of the room... --scott -- "C'est un Nagra.

Ceramic compositions are Good Stuff if you've got pulsed power. I like the Ohmite OX/OY series. They're way more available than the carbon comps, available in values that are useful for tube circuits (e.g. 10K and up, unlike a lot of other power resistors) and VASTLY more reliable. And I've seen metal film resistors glowing orange from vast overdissipation, and when they cool down they're still in spec. The ONLY thing that the carbon comps are good for are: drifting (usually upward) and charring/burning. Tim.

TNX es 73 de KE9EX What diameter was it? If it was about 5/8" or so, it's an Amphenol 75 MC1 connector. They were used often for crappy unbalanced high-Z microphone inputs on all kinds of gear, as well as occasionally for headphones. There was also a miniature version, the 75 PC1, which is about a quarter inch, and was used for recorder control and for synch signals for motion picture recording gear. Switchcraft had both of them in the catalogue as late as 1990 or so, which is the last time I went looking for them. Connector-World Supply in Seattle definitely stocks them. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

If you're making new cables, you can do what I do to ID cables. I buy shrink tubing of the appropriate size, and prior to shrinking it over the cable write on the tubing with a Fine point Sharpie. The lettering shrinks along with the tubing and looks ok when finished. Jeff -- RESTRICTED AREA. Anyone intruding shall immediately become subject to the jurisdiction of military law.

I suppose the laser print will not fade as easily as color jet print, but I'm thinking the label itself doesn't hold up well over time. Perhaps sealing it under shrink tubing helps with this.

Yep, I have restored 6 HW-30's and 99% of the carbon comp resistors were over 20% out of tolerance, they were old however.

I have plenty of laser printed documents that are well older than 20 years, and they are as clear and crisp as the day they were printed. The toner is a fused plastic/carbon compound. It will not fade in your lifetime. Paper can be had in all varieties and grades. Even if you buy the cheapest copier paper it will last for your lifetime under a piece of clear heat shrink tubing.
