Hopefully that hole is drilled from the bottom of the pot and in such a way as to prevent the metal pieces from falling into the wiper of the pot during drilling and also when the instrument is in its

Hi Patrick These resistors look OK and measure fine. Ah, that sounds like a reasonable theory. Yes, 1988. Typo. Thanks for that. I've got the boards out of the case now. It was just that the LV

Just a note about using deoxit on pots. I have been doing this for years and have gotten away with it. Some pots are sealed. You simply cannot get spray into them. I carefully drill a small hole in

Hi, ? Have some of us recently purchased a copy of - Dictionary of Unusual, Obscure and Preposterous Words....? <smile>? The author no longer uses "Byrne" as her last name and has a newer edition.

Been using that stuff for years on my weapons. Very, very good cleaner, lube, and protectant for firearms. Hadn't thought of using it for pots and such. Mark

==================== it's unusual I come across a non-technical word that I've never seen before. -Dave ==================== Stipe, bombilate, cacoethese, gowpen, steatopygic.... And no - I have never

My TDS784D has an intermittant fault on the screen which looks to be a bad contact or dry joint. The screen on cold boot is normally showing lots of vertical blue lines or blank, but after a while

Hello Jamie, I could not agree more on your statement below. But then, if more people would be aware of how useful the 5000 series equipment is, prices would likely go up :-) I have been able to

thanks, i think i am going to get some deoxit contact cleaner/lube at same time i order tants. (i get free shipping and they are fast :-) phil

Gun shops sell a product called CLP that works good. Wallyworld might carry it. Google it.

thanks...i think i'll look for something like that. phil

I might use WD-40 in an emergency. Naphtha works as a safe cleaner since it will not attack most plastics but ideally you want something that includes a lubricant. I have been using this but CRC and

hmmm what to use. my go to is wd-40 but i thought i read something about it not being a good idea. what do you think of wd-40 for this purpose? phil

i'll be replacing 3 of common purpose but i will review others. thanks phil

thanks, i do recall reading something about tantalum ESR. i see 22uf 35v 10%/20% are readily available so i think i'll just go for that. they are currently 15uf 20v 20% phil and thanks for input on

One thing I forgot to mention is that when I change a bad solid tantalum, I usually go through and find the other solid tantalums of the same voltage and capacitance and proactively change them as

Usually solid tantalums can be replaced with low impedance aluminum electrolytics of 2 to 4 times the capacitance. The increased capacitance is necessary to duplicate the tantalums ESR or dissipation

thx so far David!! t
