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

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

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

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

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

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

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

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

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

Perhaps an automotive fuel filter? Harvey > > > >

It's in place. It's not enough though.

The Metcal has a cotton or felt cube that filters this also. I'd imagine after years of use it might be wise to either clean or replace the venturi (IIRC it can be popped out and a new one slotted

I said the CRT cable (thinking of where the cable leaves the HV unit) but Harvey said it straight forward: in the vicinity of the HV unit . This way you measure the HV transformer switching frequency

The Hakko desoldering station I have has two sets of inline filters.? One, a kind of springy thingy for stopping the solder bits and pieces from flowing into the pump, and the other a fiber disc for

The failures I saw with the Beckman pots were in telemetry receivers being built for NASA. They were the ones in use when we lost that last shuttle. The media was waiting for information, but when you

The silver was a very thin film that was applied to the substrate before the resistive element was printed on top of the substrate. The the terminals were crimped over the other end of the silver

Yup, you could be right, I just looked at a copy of the datasheet I found on the web. The strap line in the sheet is "Now you can specify Bourns for cost-sensitive applications" the sheet is marked

Hi Michael, You know, I've just been looking at that and you could be right, but I *really* can't tell how those connections were made! Comparing it with the apparently identical one on the old board

About 6-7 years ago, I used Bourns 3352 Cermet open-frame potis as a standard for replacements on amplifiers. I figured that open-frame would dissipate heat better. After about 2 years, I started
