Hi just a bit of information we have a lot of the New scope literature in the?Catalogue's file on this site Regards Paul

Fixed my attenuator problems using Joe's board.? The 3336C with the Aromat relays are not the same spacing as the 3325 so the PCB had to be sheared.

hi, In the event of instrument CRT death, one might want to do a replacement having an LCD display: The question is: -- are there any existing modules ( or schematics, or projects )? that might be

The only one of those I recognize is the 3456A DVM, as I purchased one a year or two ago. eBay prices range from less than US$100 to several hundred depending on condition, calibration, and the

Hi Richard, I have never seen anything that would lead me to believe an end cap was glued onto the body of the capacitor, but maybe that is what they did? Or, maybe the capacitor was built in

Hi Chris Welcome to the group but your problem is not new and one that most on this group suffer from Covid shut down for the past 2 years has meant a lack of rallies / to reduce our stock and

Hello Group! I'm trying to get a handle on my test gear and decided to start looking at my HP hoard. I need to decide what to keep/fix/purge/replace and finally joining here seemed like a good first

Is this descended from the same company? Solar Electronics Co10866 Chandler Blvd. North Hollywood, CA 91601 And what about

?? I may be wrong about the voltage value, I am going by memory of the advertising. ?? I have wondered the same thing about the oil filling. Its possible the casings were cast and the winding

Hi Richard, Bumble bee was a descriptive name based on the colorful bands used to indicate the capacitor's value and voltage rating. It was certainly not a brand name. Tektronix used numerous 400V

Added Option 001 to my otherwise working 5342A. S/N 1840A01105 which has no line voltage select provisions on the rear panel. The 10MHz Dale TCXO assembly was replaced with a 10811-60111 OCXO. After

??? I want to respond to a couple of things in this thread. First of all, there were other brands of molded paper caps. None of these had the consistent problems of the Sprague caps of cracking and

I have one. It was from a "Real ICE" kit, which I no longer have. Looks like the same cable. You're welcome to it for postage from Colorado USA. Pete

I can have a look ... but the YTF auto-alignment goes through and passes, as expected, which should sort out any tracking anomalies. [email protected]> wrote:

Robin, Did you try the Tracking Adjust (in the amplitude menu, I think)?? You should be able to get a fairly smooth manual peaking response if the YTF current drive is working correctly. --John

Thanks for this very good explanation. In addition to the points you made, I have read the oil fill was often complete, and hydrostatic force would test the integrety of the plastic. Shrinkage and

Does anyone have one of these lying around - it is a 14 pin socket (2 x 7 way) to flying leads with free sockets to connect to

BB capacitors were molded as well as the technology of the day would allow... That is not why they cracked. The problem is the plastic they used, like most plastics, shrinks slowly over time, and the

All spiral wound paper/mylar/film capacitors are polarized from a noise perspective. The outside foil wrap of the capacitor will be connected to one, or the other lead. Depending on which way you

After some investigation ... and with the levels from the manual, it would appear it is the YTF that is faulty ... the attenuator is fine, levels check perfectly ... I cannot imagine it is the relay,
