Learning to bodge again..
Even though I've got an ongoing AYA 5 DAC build happening, I just can't seem to keep away from vintage DACs. This time a Wadia X-32 - I know nothing about it except it's the later and cheaper iteration of the X-64. Having been nothing but impressed with both the vintage Camelot Arthur and original Micromega Duo (currently in system) I decided to take a punt on this early and faulty one.
Seller advertised as faulty, because toslink input was not working. But then updated ad that BNC had issues too.
Not even tried to listen to it yet, just stripped it ready for a recap and ordered a whole bunch of caps from Mouser - there's loads of 1uF and 10uF electrolytics in there, there'll all be replaced with Wima MKS2 films.
Case has been opened before, but no-one has replaced anything as far as I can see - non-functional toslink was not helped by the ribbon cable not being connected to main PCB.
So far I just tested 2 of the 1uF caps - both OK from capacitance, but ESR up at 8 & 10 ohms. See photos below - the 2 regulators that are heatsinked also have an overheated resistor - both read OK currently at 22 ohms and I've just lifted them up off the PCB a bit to help with cooling. Hopefully a recap will fix it.
Anyone any experience with this DAC? Any good?
Anyhow, pictures
Whole PCB removed
Over heated resistors (bad quality, sorry)
Thanks, Richard
