The can is a big ol' heat sink. If you can carefully cut it away from the top of the board (or, at least, remove as much of it as close as you can), it should help. There may be limited room and

Ugh, those are a pain. If you put too much heat in the board the trace will delaminate. You need a good desoldering tool. At the least a vacuum tool, maybe some chip quick, solder braid as a last

Working on a Tek 475A/DM44. The 5V filter cap C1452 (5000uF 25V) is intermittantly open. A strange one. I'm struggling with removing it, desoldered the 4 terminals, tried heating all 4 of them

Thanks, that's what I thought, just wanted to confirm that. Still could use both SMs. Thanks

What is not clear? Although the index numbers on the parts exploded view in the 5B44 manual at TekWiki are a bit hard to read, I find them legible enough to find those index numbers on the mechanical

Hello Howard and all, As Jon mentioned it can very well be that the mixer diodes have been destroyed. Below are some level problems I encountered in some of these analyzers. Please check Q350 -

Hi all, I have a rather sad 5B44 with broken timebase knobs. My copy of the service manual is a not a clear enough scan to tell for sure which part numbers these are so I cannot give specific

Just went to track it down. That's the one! https://fairradio.com/product/390a-mbnc/ Thanks for the lead. I suppose they're not as rare as eBay made me think.

Fair Radio Sales is another source (at least until the end of June, 2024) for these connectors. Shaun M.

I've been trying to find a BSM panel jack connector for a while now. Usually, it's the 012-0127-00 that the manual calls out. I had nearly given up. But I was visiting a friend of mine who owns a

I keep some old machines running for special purposes. I still have a working Win98 laptop with an original Pentium for old programs that have to read from and write to the UART registers. I need them

Tom, Basically the costs are relevant if the present software can no longer be upgraded to add new features if the older machine won’t fully support migration to a new OS (i.e drivers will no

One detail I want to add. If the diameter of the replacement condensers don't fill the can to the limit, I like to use a strip of plastic cut from a frozen food microwave tray to form a ring inside

Just to clarify, the can is turned upside-down for that. Barry - N4BUQ

I've done this by making the cut about 1/2" from the top of the can. A hacksaw blade taped to a small piece of wood allows one to cut and slowly spin the can while sawing so that the cut is all the

A couple of closing comments from here….. Tom Gardner: With respect to your comment: “Why would buying a new computer mean you must throw out the existing one? Can't you run old stuff on the

When I rebuild a condenser, I use blue shrink wrap over it because it covers the cut seam and is authentic, I have seen plenty condensers from the factory with blue sleeves. I put a wrap of aluminum

You can try making one yourself. As far as I know, it's just blue clear plastic. Someone else here made some tek CRT shields using some blue plastic. I'm not sure what to do with the tan though.

I have done this on a lot of multi-cap cans in old monitors. The multi cans bulge at the bottom, so I cant use a pipe cutter reliably. Have to use a hacksaw...with very fine teeth. Clean up with a
