Hi Phil, Yep, that's me. And I did get your email and have sent a response. What I do is entirely non-destructive. I just need to take measurements from the existing foot Jeff

Hi, I have one of these with no disks, has anyone got a sample waveform disk they can upload to the files section please? I haven't checked what format the disks use, I guess an imaging tool such as

Hi Jeff, Are you N0dy?? If so, I just emailed you about your 400 series feet. If your process is nondestructive, maybe we can get Lee H. (on list) to volunteer his one surviving complete foot for

Hi all, I'd be willing to undertake the 3D modelling and printing with a durable nylon material if I could get my hands on a reasonable existing foot to take measurements from. I've already developed

Hi Lee, I have been considering making a mold, but I am going to have to learn how... If I can figure out how to do that, without harming the example, I will get back to you on this... Thanks for

This is such a common malady that a few people have developed replacement feet. One reference is /g/TekScopes/message/144184 And I've bought a few sets from Fred Usack on ebay,

Why not "print" a foot and use that to make a mold. Then you can cast them in more robust material. 73. Dick, W1KSZ wrote:

It can be done. I've 3D printed feet for the 465 based on this model I "designed" based on the original feet: https://www.thingiverse.com/thing:1410827. Printed in PLA, they are functional but I

My 335 has ONE good, complete foot that I would loan out in the hope it might lead to the production of four new replacement feet.

Hello all, The feet on the rear of my 335 are crumbling apart, literally! I talked to Walter at Sphere and he has nothing even close, and searches on the net reveal nothing... so, I am coming to the

Well, this shifting does seem to be your problem - especially if you're measuring this at power-on, as the slow start should increase the nominal voltages by ~10V initially. So if you're measuring

Use this picture to make the scale. Think new scale looks good and will work. Make 3 different types to try the illumination under the scale. I think the better one will be with the foil on bottom of

Measurements are taken at power on.

Ok I have checked the Voltage at Q1980 collector, with r1878 full CW (max grid bias) = 60V, with r1878 full CCW (min grid bias) = 120V, so there is the correct range but shifted of 13V more or less.

Also some plug-ins like the ubiquitous 7B53A used chiefly in 76xx mainframes have no built in illumination anyway so adding the lamp power modification to the mainframe makes no difference for them.

Thankyou Roger and Menahem for your recommendations ... my Scope has run trouble free for quite few hours now ... and I am discovering its functionality is more complex than my el cheapo scope .... :)

Using the TM500 PSU / back plane as a standalone card tester : I did the same as Edward some years ago before I made up my own (TM503 ) plug in metal frame extenders, (turned out to be a fiddly job)

I was going to say yesterday, they should have just sent you a new nozzle and tube. At least they finally wised up. And yup, I meant both ends of the tube, you got me! =) --Eric Sent from my Samsung
