Re: Gauging interest in custom made Canare coax cables?
> Here's some rough prices to give a ballpark idea.
Thanks. Reasonable, but I can get decent amphenol connectors for similar / less (when counting shipping), will probably pass. I am familiar with Canare, I like their L-4E6S for audio stuff, used to be able to get it cheap at a local shop. Wasn't aware they made coax however, good to know (although probably nearly unobtainium here in NA). |

Re: HP 5315A With Destroyed Gate Pot and "frozen" Frozen Knob
..you're most kind. I received a stern lecture a long time ago on the Tek group never to leave a thread hanging without a resolution and, being an obsessive, compulsive [former] software developer, I did meticulous notes on my creations, mods, and changes for the developer who came after me which was often..

He's talking about a 5385A...not exactly "vintage"; certainly not to the level that you're talking about here.

Don't know it would work with PCB mount caps, but when I restored a bunch of 1940s-1960s Cossor and Telequipment 'scopes, I found that as modern caps were so much smaller for a given capacitance/voltage than the originals it was easy to split the can (round the circumference, above the 'crimp') and replace the guts with a new cap. Then put a bit of clear heatshrink tube over the whole can to hold the two halves together. --

Re: HP 5315A With Destroyed Gate Pot and "frozen" Frozen Knob
Many thanks to those who helped in this thread. The advice and encouragement (and proffered manual) yielded sanitary unit and a workaday solution for those who have smashed their gate pots to smithereens.
Before I proceed with my resolution, I need to ask about the protocol of placing items in the files section. I have a decent manual passed along by another member and I'd like to place it in the appropriate directory along with a more formal documentation of this resolution. The Manual is a .PDF file about 15MB in size and the write-up is about 600KB. If there is no taboo on uploading these, I shall do so. Herein hangs the tale. Firstly, the litany of problems: ?? The gate pot ¨C a 500K Ohm unit with a switch built in to accommodate a ¡°HOLD¡± function was destroyed. ?? The A channel Sensitivity pot knob was unremovable. Some genius had jack-hammered one of the two grub screws in place with one of a different size and threading. No amount of coercion could extricate it thus it fell to Dremel sawing and was destroyed. That left me with two decent knobs and a gate pot with none. (The three knobs on the unit are identical. A spare parts Tek 7700 series plugin knob served as a replacement.) ?? Similarly, the input assembly ¨C where the two input BNCs reside ¨C was secured by four Philips head screws one of which was fused in place. (It is always that way, isn¡¯t it?) This last point was remedied by something I saw on a YouTube video. The Kroil had not arrived yet but bathing in 3-in-1 oil did nothing to budge the screw. Some guy said to take an ordinary rubber band about 4-6 mm wide and push that into the stripped Philips head with the screwdriver and, pressing down with as much weight as is possible, attempt to turn the screw. I was very skeptical of this but, to my amazement, it worked! (Similar success later experienced with another item in my shop!) Anyway, a member of the group offered a remarkably sanitary copy of a .PDF manual with pictures and schematics which I gratefully received so I was off and running! The first step was to examine the spot where the gate pot resided and to figure out how the gating function worked. Below is a shot of the A1 board after the pot was removed. It was very easy to wick out and clean the holes and what was left was a mostly intact gate pot case from which I extracted the necessary dimensions for a replacement. The original was, as stated above, a 500K ohm Bourne potentiometer that six leads to be accommodated by the six holes shown below. The three in the front were for the delay and the three in the rear were for the ¡°HOLD¡± switch. Also below is a schematic excerpt of the gate pot with the hold circuit. Note that the circuit is simplicity in itself. The gate pot¡¯s wiper runs to pin 6 of U2 and controls the voltage. The ¡°HOLD¡± pins grounds pin 7 of U2.? (See the picture below of the connections after the original pot has been removed.) In Searching for a replacement, I located a Bourne 3310 pot on eBay from a nearby seller. (Image of the pot's dimensions below.) Mounting the pot is not a flush fit; you¡¯ll have to do a little lead bending to get the pot seated correctly. I accomplished this by mounting the pot in it¡¯s panel hole, bending the leads backwards at a 45¡ã angle and carefully fitting the panel in place. Then the leads can be pushed into the three front holes and ¨C eventually ¨C soldered in place. If you are a tad squeamish about whether the pot functions correctly or not, just push the leads such that they make contact with the board, fire the unit up, and rotate the shaft. Fully CCW will cause the gate LED to pulse quickly and fully CW will cause a pulse of about 10-15 seconds. ? I added a simple switch to implement the "HOLD" function wired as shown below. Caution should be taken to use a very small switch and wired as shown so as to allow the front panel to be removed later if necessary. It's crude, but I could not resist positioning the switch such that the handle would point towards the "HOLD" panel label when on.? ? Good luck and good hunting! -- William, k6whp -------------------- "Cheer up, things could get worse. So I cheered up and things got worse." |
