Re: Slightly OT - Bourns trimmer pot failure
I have seen most of it gone, but never all of it. Are there any others like it used in that model? I would replace them, and do autopsies if there are. Michael A. Terrell

Re: Slightly OT - Bourns trimmer pot failure
Hi Michael, Did that and not a trace of anything, just a ¡®bruise¡¯ where a dimple in the stake has been pushed hard against the surface as if to make contact. I am really beginning to think this

Re: 7704A Z-Axis Problem
All shields are in their right place as far as I can tell. I will check the spots you recommended and I'll report back. Thanks!

Re: New file uploaded to [email protected]
In case it isn't apparent from the information below, I created a small PDF that outlines the procedure I used to replace the electrolytics in my 465B using an auxiliary PC board and snap-in caps.

Re: Pimp my TM5003 ! (swapping fan with a quieter one)
Hi Ke-Fong, Our ears respond logarithmically to sound so it is hard to anticipate what 32dB might sound like. In addition humans add an additional factor of perception that is hard to predict. 32dB

Pimp my TM5003 ! (swapping fan with a quieter one)
Hi everyone, The fan of my TM5003 is a bit loud and it has a "rattling" component into it. This is not as bad as a TM5006, but still quite loud. That would be ok for a professional or industrial

Re: Replacing Electrolytics in a 465/465B
I had a set of those made up but decided not to use them here. One problem is there is one large hole that could be a bit difficult to fill with solder. The other thing I didn't really like is that if

Re: Desoldering Iron vacuum
You don't have to take the pace vane pump apart. When the vanes start to stick, just put the hose into a bottle of 99% IPA, and snorfle up the alcohol. Put a small hose on the pressure output port so

Re: Desoldering Iron vacuum
That's another data point saying a cold trap is good for long low maintenance. "S shape metal insert that congeals the solder" ==> cold-trap

Re: Desoldering Iron vacuum
Yes, that is why I was suggesting a section of pipe with TP wads -- it would be a cold trap and a big wide filter, and it wouldn't have to be vacuum perfect since only intermittently pulled down. For

Re: Desoldering Iron vacuum
My Pace station desolder tool has an internal vac pump and the tool has an internal glass pass-thru tube with an S shape metal insert that congeals the solder and a cotton plug that trap vapors. If

Re: Replacing Electrolytics in a 465/465B
Another method that works well is to use individual adapter boards for each cap. The boards are roughly the same diameter as the original caps and allow a modern snap cap to be used. You can make the

Re: Desoldering Iron vacuum
The flux fumes will go right through the fiber disk. I use a Pace desoldering system with a cotton like plug in the solder capture cylinder and a fiber filter at the end of the tubing just before it

Re: Looking for Power Cord for 400-series Scope
That's what I ended up doing. If your feet are in good condition you can just tuck the plug end between the cord windings and it will stay put. Paul

I also have a Metcal system, absolutely love it. I use a $39 HF compressor for it. I bought it because it was cheaper to buy the whole compressor from HF than individual compoenents to add on to an
