Rejoin? Should be re-instated, without formality. RL

FWIW, the item "HP Elastomeric Keyboards + Trim", those 3 parts in the top left of the image are the power and CRT display soft buttons for the Tektronix TDS500/600/700 series scopes. ;)

Hi all, I have a TDS620B here I'm doing battle with. After repairing the power supply, Iit seems to be failing SPC on channel 1. I've tried replacing the hybrid modules with spares, to no effect, and

This is what I wrote in the 'Dennis' subject heading: A dispute with group co-owner Michael Dunn, as I understand it. In a private message, Chuck told me roughly the same thing. I do not have

In a private message, Chuck told me roughly the same thing. I do not have permission to post that message and thus, will not. I have not asked Mr. Dunn for his version of the dispute as I have never

My guess is de display PCB. It depends, if you have the older 2465 it is the horizontally placed PCB in the richt end corner. If you have the newer smd type A5 PCB the display pcb is included on the

I'm just finalising another 2465 repair project and discovered that the Delta V/T cursor is not visible. The Delta REF cursor is present and adjustable in either V or T mode but in both V & T mode the

Thank you, David. DaveD

Chuck has been invited to re-join Tekscopes but has declined. If you wish to partake of his wisdom you are welcome to join Tekscopes2. Cheers, David

You need to remove the whole PSU block. Then there are comb connectors between the A2 and A3 PCB's, with plastic clips to release. And finally, I always snip the defective component's leads, right at

Does your 492B have the OCXO reference option? If so, then you just need to remove the large screw that covers the trimmer and adjust it (carefully) with an alignment tool. If not, the only available

Is it possible to adj the master oscillator in a 492B? I cant find anything in the manual (so far). If i can get a GPSDO, I could adjust the 492 after many years - but it may only matter in count mode

The 453 is extremely repairable. It has no proprietary ICs, for one thing. Replacement Nuvistors are surprisingly available, and even if that weren't the case, they can be replaced by JFETs without

The first thing you should ask your friend is what the serial number is for his 453. w140.com has the operator and service manuals- there's one set of manuals for serial numbers up to 20000, and

That sounds a lot like an error code, which is documented in a very small and obscure portion of the manual. There's a similar type (guessing here for the DC5030A) of error message on the DM5010

We are finally done re-organizing and photographing new items, you will be able to see them HERE Tuesday, February 15th: https://www.sphere.bc.ca/test/stuffday.html We tried to satisfy as many

A while ago, I found, at a ham swap, a TM500 DC5030A counter., SN B011601, visually good condition, but, on being powered shows what, for me, is an odd fault. With or no input, digits on te right side
