[time-nuts] TymServe TS2100 dead power supply

[Bob Martin]

Many thanks for the replies on this one.

Before I made the first post, I'd pulled the supply, given it a visual and nasal inspection, checked the outputs for shorts, and powered it up on the bench. Dead (and dead quiet, not even the tick-tick-tick of a switcher with a shorted output).

In my perusal of the archives, someone observed that it was a standard Astec LPT-42 supply. Lo and behold, a label on the primary filter cap of my dead switcher identifies it as an ASTEC LPT42.

I looked around -- Mouser and Digi-Key were within $1 of each other. Not too surprising, actually, pretty much ALL the sellers on eBay wanted more for units of dubious heritage than Mouser and Digi-Key wanted for a new one.

Already had some bits and pieces I needed from Digi Key so I added a new LPT-42 on to the order.

New supply arrived. Installed, connected power, turned it on and things light up. Pulled the fuse out of the old supply to save and tossed the old supply in the bin. Last time I got a good electrical shock (if there is such a thing) was from a faulty switching power supply; another reason to diagnose this one with my wallet!

Back in operation again. Yes, I *still* have to deal with the old GPS module and the issues it creates. But my TS2100 is back on the air, driving my IRIG displays and providing 10 MHz to various pieces of equipment.

RANDOM QUESTION -- does anybody know of software to *generate* IRIG time code? Something in C that's adaptable to a modern micro would be good. In something like a Raspberry Pi 3, IRIG generation would make a nice addition to Lady Heather...

cheers and 73,
