Except Scotty.

Pete, The keycap has two little tabs that snap over the momentary switch. I will send a photo if you have not resolved this yet. Removing the keycap requires access to the button board because the

Or anyone who had a red shirt- that was the kiss of death! -Dave ?new character on Star Trek, but not Uhura, you are dead within the hour. At least it seemed so.

Couple of questions and a comment. One, why can't I get the print at w140 ? I went to that Polish site and got it and it is scanned terribly and there are tings missing. Then I went to BAMA and it

Something lost with youth. They were better when young and can really get scared. Later they lose some of their bite, or more aptly we lose the ability to feel it. It's almost impossible for a show to

That is fine where it is possible. Alas there are places where it is difficult to make such a replacement. Just for example -- there are some high capacitance (something like 1,000uF 25V) wet

It has only happened in 20% of my 1502s. I seem to have a fetish for the damn things :) ISTR the 25V rails are not low current, which might increase the stress.

Interesting - must check mine. Wonder why they used them only on the +25V rail, which is only used on the high voltage board, to feed the switching transistors on the primary of the HV transformer,

forever Well, yes. All I'm saying is that I have identical plugins (such as 7A26) in which at some point Tek went from tant bead to aluminium electrolytic. So substitution is tried and tested. And low

The only thing that can degrade a rubber-sealed wet tantalum, and also (particularly) axial electrolytics, is the flux cleaning regime. As an example I bought a NOS P6046 differential probe, and

Hi Craig, You would think that should be the case but as I commented on a recent thread, I've got a whole bunch of Tek 7000 series stuff working over the last couple of years, most recently the 7912AD

The only place I've ever seen a wet tantalum leak is in the 184 TMG; fortunately, corrosion was limited to the capacitor leads themselves.? There must be environmental factors at work, because some

I have had axial tantalum capacitors leak and destroy nearby PCB traces, specifically C6246 and C6341 in a Tek 1502 TDR.

Better yet replace them with higher voltage rated ones if they are available. 20V tantalum lasts forever on 5V rail as well as 35V one on 15V. I can send you a handful :) They _ALWAYS_ leak sooner or

The only type you have to be concerned about are bead tantalum capacitors used for local power supply rail decoupling. Colour is unimportant. They will be 6V rating on 5V rails and 16V rating on 15V

Same as for the Xformers Kurt, very valuable. Thanx for that, René

Very interesting and good piece of information. Thanx, René

I am guessing that this subject has been hashed over a number of times but as I am fairly new here i will ask away. I see on the different boards from the scopes I now have some from same unit and

The termination is not required for the low and medium frequency compensation which is just as well if a x10 probe is used because then adjusting the x100 attenuator in a 465B requires a high level

Timothy, You do not mention the use of a 50 ohm termination at the scope end of the BNC cable.This termination is necessary in order to have a proper signal.Compensation adjustments should be done
