Raymond ACK on all, I forgot about " show quoted text" to see interleaved response. I referenced Jim W avalanche and Tek TD pulsers only as possible alternatives to Leo Bodnar, the gold standard

Sorry for delay and thanks!

I should probably mention that the schematics are NOT 100% accurate. What has been published is a scan of the last pre-production drawings. A final production set was never completed because there

It seems to me there was a pressure device for forcing cleaner around the shafts. It screwed onto the mounting and pushed cleaner in around the bearing. Have not seen one for years. If these

Firstly, thanks for all the helpful, and generous, responses. I decided to dribble Deoxit ¡®down¡¯ the spindle entry and it appears that it may well have got to the track and adjustment is very

Hey Ferrous, This is amazing, it's sure to extend the life of some of those TDS420/460 scopes that otherwise would have been landfill - thanks! Siggi <ferrous.steinka@...> wrote:

I have 2 potential solutions. The first is to simply swap the 2 pots since they are both 10k. It is unlikely that the bad spots are the same in the 2 pots. The second is for me to send you 2 pots

Amazing!! Now what is missed is more schematics for the 500/600/700 series ? but maybe more importantly it would amazing to find the service software they use to find the problems. Basically what

Would it work to place a parallel resistor to effectively move the defective part? Thanks Barry - N4BUQ

Jon, Do you mean that you couldn't see the following? Sometimes in the web interface you have to hit the button "Show Quoted Text'. Raymond

I have an early 130 here (brown case) - those look to me like regular RV4 style 2w 10k pots which can be had on eBay for around $10 NOS. Such as RV4LAYSA103A. I do notice one of them says "S-taper"

I don't disagree that it will be difficult but so far I've got a pretty high success rate from posting want ads on other rare items (I found a guy with 4 570 curve tracers, bought one, managed to get

You are going to have an extremely hard time finding a P11 T52 CRT. I bought three 532¡¯s from eBay recently, and they all have P2 CRT¡¯s, which now reside in three of my 575¡¯s. Only one 532 was

Is it possible to drill a small hole in the case +- 1/8¡± and give it a small shot of Deoxid? If that works and you feel so inclined, you can put a small amount of wax or some other sealer to close

Yea I've spent quite a bit of time researching it at TekWiki and other places over the past year. They definitely exist - I've seen at least two, and were documented in the manuals. You could get

Having does the necessary restoration on my T130L-C, I am now running through the calibrations. I have an issue with the 0-3 and 0-10pF calibrations. The controls, R100 and R99 respectively., have

Ray, Bonjour No idea about the divider, the output must drive a 50 ohm load, at leas 1 V Easier with discrete parts. No freq divider needed. Usually a 1-10 MHz rate. many fast pulser designs on

Hi all, As I am incompetent in this field you will take this with indulgence please but as Raymond above asks for "Any comments welcomed. " I add my 2€ cents... To generate a square signal at any
