I built a loop supply from a dc-dc converter and a resistor to limit the current.  Cost me about 10 bucks from Amazon to build it.  Let me dig it out and take some pictures.

Forgot to add part of my main question; of course it would only come to me after I hit "Send" on the first e-mail...

Are there any particularly sensitive parts of the ST-5000 that could go awry in the hopefully unlikely event of poor shipping practice (packing and/or handling)?  This one's (understandably) got a hefty shipping price so I'm weighing that factor in, too.

Hi all,

I recently saw an ST-5000 up on eBay (should have looked sooner haha).  I had already previously ordered the IRL demodulator thanks to advice from you, but since this unit presumably contains the loop supply, then I assume that’s why it’s so sought after.

However, I’m sure there’s the gamble of whether or not it works as intended. To any ST-5000 owners: did you have to do any restoration on your unit when you first got it? What could be a common failing point or any other considerations for the unit? I still am deciding on how I want to design my loop supply if I stick with the IRL route as I have limited bench space, but just putting this out there - keeping an eye on if I might have been impulsive jumping onto the IRL unit or weighing if I will regret going for the HAL if I do haha.
