Hey Dennis, this just occurred to me - if you can't find any off-shelf miniature tube style plugs, how about just cutting some pin stock to make them extra long, and jam them into a socket to form a

Dennis How many of the 7 and 9 pin plugs do you need? Are you looking for a significant number? 73 Dave, ZL3FJ

stuff that disappears does so for a reason. Maybe you just simply don't get tubes with that base that are any interesting at all. No point trying to accumulate stuff that's boring other than it has

Hi Cheater, In a pinch I did make a 9 pin plug using 0.040" bus bar pushed into an existing 9 pin socket, with a piece of PVC tubing around it, and I potted the entire thing. What you get is crude,

Am I missing something... why not just take a bare FR board and drill some holes in it.. use two boards for rigidity... and pot the whole job? <TekScopes@...> wrote:

Dennis, They have the 9 pin Socket Savers. I did not see any 7 pin. Quite awhile ago there were some cheap car stereo players, maybe eve 8 tracks, I forget, I serviced them once. Anyway, they used a

Hi Bill, In my case I needed tube PLUGS that would plug into a tube SOCKET. That is my problem. I am well aware of Tubesandmore. They certainly have a nice selection of 4 pin, 5 pin, 7 pin, 8 pin ,

I have 3 Tek 2445 scopes and one Tek 2430A scope. While idly bumming around eBay, I noticed that it seemed to me the 2445s were less common and on average more expensive than the 2430As. Seeing as how

Dennis and all, Has everyone been overlooking the best source for tubes and related hardware? https://www.tubesandmore.com/products/tube_accessories Bill KB3DKS

The 150MHz 2445 came out concurrent with the 300MHz 2465, costing $3250 vs the 2465's $4750. Double the performance, and only a third more in price. More the wonder is why any sold at all? -Chuck

The Little Mountain part/Annex of Hill AFB has an interesting history. originally it was a specially built wind tunnel for testing the Ramjet engines for the Bomarc. After that program shut sown it

Voltages at Q114 & Q115 stay exactly the same when switching between ch1 & ch2. I have double checked voltages and there is a slight difference to what I'd previously reported: U130 Pin 13 1.97

The 2465B stores all of the offsets, and gain changes necessary to make the scope in calibration in the NVRAM that is on the A5 board. The only adjustment pots are in places where a resistor must be

Chris, The digitised output only appears on the XYZ connectors, I use a 485 in XY mode and found that the Z connection did not add anything useful. When I press the digital button. Tha analogue

Chris, The fastest sweep speeds need the x10 magnifier so you will have an apparently wide scan. On the 7B90P there is a 'mag' led that comes on. The graticule should show 10 x 8 equal squares so

Dennis and Aris are up here at sphere this weekend, he is bringing back the little meters, and the 570 meter, any other requests? we need to know in the next few hours. I also have clean working

Wow... That's cool!!!!... And the way he made for the shapes to "sing" as well! Awesome! <TekScopes@...> wrote: [Non-text portions of this message have been removed]
