While looking for some manuals I found the bitsavers.computerhistory.org site. It has some very high quality manuals including TEK ones. Regards, Brian

Thanks. The ebay listing is for the pressure transducer part of the probe set I have. Definitely labeled as Tektronix gear. The probe assembly has a Lemo power cable and a P6137 style BNC connector

Hi David, and thanks for the suggestion. That could well be the case. It seems that I need to figure out which part of the PSU board supplies the horizontal control circuit? Whatever is

Thank you, Jared, for the gesture. I really appreciate it. 73!

A glow off to the right might suggest that the left horizontal plate signal was disconnected ...

Further testing.. Swapping the known good PSU and top boards into the original 2430A reveals that the display problem is indeed created by the original PSU. The original scope starts up and has

Shall keep this short, however... swapping the PSU from the 'original' (no display) scope into the working 2430A, brings back the 'BEEP' and the glow off of the right hand side of the CRT (no

Ok - thank you. I'll try it as soon as I got my 3034C

These schematics are for the TDS540, but the power pins will be the same: https://w140.com/tekwiki/images/c/c9/TDS540_Schematics.pdf Jared

Thanks for the reply... After having spent some time going through the CPU/CTM schematics I am inclined to agree with you, it's more probably a mechanical connection problem somewhere. The un-read

If your probes don't seem to be Tek or related to engine analyzers, then also look at HP's foray into laser interferometer systems, which had some transducers for barometric pressure, temperature, and

I had to look. Here it is. Good luck. https://w140.com/tekwiki/images/a/a7/062-1074-00.pdf Ed

Are these Tek products? If so, look at the engine analyzer line from way back. One of the Tek "Concept" book series addresses this so may have some pertnent info. Ed

In my collection of probes, I have a P6610 physical measurement amplifier and three P6610 pressure transducers. I don't have any documentation and a search of the usual sources has come up empty.

Do I see a 27xx spectrum analyzer? Expensive for parts but for dirt cheap project maybe..... The rest is landfill.

I am here as well. <david.partridge@...> wrote:
