Recently I bought an old Dynatuner FM-3, supposedly in good working condition although it looks like it spent the past few decades on an attic somewhere.
This FM3, once cleaned up and properly revised, would go perfectly with my previously restored ST-70 and PAS3, however there is one major problem:
It has the original PA509 power transformer instead of the optional PB-012 that can be wired for 240V operation, and I live in Belgium where we have a 240V/50Hz powergrid. Clearly I didn't do the proper research upfront as I was under the impression that the FM3 could simply be switched to 240V operation without any additional requirements.
Those PB-012 seem quite impossible to source. I checked on dynakitparts, dynacodesigns, triodeelectronics, Ebay, ... but can hardly find any reference to it ever having been available. I do know they exist, as these FM-3's do popup in Europe every now and then.
So my questions:
- Does anyone know of a viable replacement for the PA509 that operates on 240V, or is there a way to rewire the PA509 to do so?
- Or do you know of a source that might have a PB-012 laying around?
- Does anyone have the specs on the PA509/PB012? If I know better what to search for, I might be able to find a suitable replacement online.
- One option I've been thinking of is to have my PA509 professionally rewound for 240V operation, but I honestly don't know how much that would set me back.
I'm picking up 230VAC-110VAC convertor tomorrow, which should work just fine, but eventually I'd like to hook it up directly on an outlet on my PAS3, just as I do with my ST70.
