Repair options for Placette passive linestage?

        I see!

        But, as I mentioned, "Any competent Tech should be able to convert the plug."

     Rewiring your old DC power supply's DIN connector, especially while having all applicable components in hand, isn't Rocket Science.

Appreciate the referrals, but both options are configured with barrel connectors. The issue I’m running into is finding a power adapter with the 5V, 1.2A, 6W spec that has an 8 pin DIN output connector.

Also, while Placette’s website is still up and running, they are NOT operational (Guy’s widow confirmed as much to me), so I caution anybody against hitting the Buy button on any products.

          Here's CUI's new version, from Mouser:

           Placette (which seems to remain operational) still offers replacement PCs, for  their units:

         I owned a Plcette Passive Linestage, for a few years and loved the purity.

Yeah, I really hope it is a power supply issue since that should be a very simple swap of an external item. The issue I’m running into is that I can’t find a replacement 8 pin DIN power supply anywhere! It’s as if Guy was the only guy (no pun intended) persisting with this type of connector, and no one makes them anymore. The mfg is CUI. The model is EMSA050120 and the part number is EMSA050120-P5P-SZ (output 5V, 1.2A). I would of course welcome any suggestions for sourcing direct replacements or even suitable substitutes.

Just want to make clear my unit didn’t have an issue and Guy just wanted to make sure I wouldn’t have any power supply issues down the road since he mentioned some do get flakey down the road.   If I notice any oddity, just swap the ps unit he gave me.   I just did the swap anyways as a just in case.  Nothing improved or got worse.  Just peace of mind

Does sound like a power supply problem.  Many years ago I asked Guy about a possible issue I thought I had and Guy was quick to send a power supply replacement.   Very said that he is no longer with us and explains any he hasn’t responded to my emails lately. 

FWIW, I don't know if there is a buffered circuit in these units. AFAIK, the power supply exists simply to provide remote volume control and input switching.

This is the product listing page for anyone who's interested: http://www.placetteaudio.com/passive_line.htm

@jasonbourne71 buffered circuit isn't passive means preamp isn't passive.

@czarivey If the passive line stage has a no-gain tube or transistor it has a power supply. Buffered circuit to reduce output impedance.

I hear you on passive components not requiring power, but the volume control here is either via remote or via an up/down toggle switch on the front of the linestage. and neither work unless the unit has power. That suggests to me that the linestage isn't passing anything through unless it has power. That isn't a malfunction. It's always been that way. The way this particular unit failed (intermittent operation, and then completely dead) would suggest it's a power supply issue, and frankly, I hope that's all that it is, b/c that should be a fairly simple replacement of the external (plug into the wall) unit. Just curious if anyone's experienced anything similar with Placette passive units.

Take it to a local technician. Ask your local dealer who does their repairs. 

everyone seem to think their prized piece of audio gear is only repairable by the manufacture,  That's just silly.

Well unless there is some component that's only available from the manufacture but that's more rare then you think. Any competent electronics tech should be able to fix 95% of problems with any piece of audio gear.  granted parts being available etc. Sure if you have a case/housing/faceplate issue maybe the manufacturer but all the electronics components should have comparable parts available. 

Power you need only for remote otherwise passive preamp should work without power.
