So i´m back with my receiver threads i finally got some time to dig in to this one!
after my last receiver thread the DUX-TA-12000 there was a vote on what i should restore next and this one was the winner
anyway here it is. its sort of working, it clicks (good sign), but it takes awhile before any music is coming through, i bet that will be sorted out along the way as we go. according to previous owner it has been in for service where they "lubed the relay"? yeah right! think i´ll just replace it
i think this unit really means business! judging by the looks of things!
bet this will be a killer once finished.
as allways: i go in to this with the intetion to totally recap it, replace any crap trannys i find, and also have a look at the signalpath where i will replace any tantalums/lytics for wima MKS2. but there is allways something more to do.
feel free to come with ideas on how to make this monster a top performer.
here she is, with some broken bulbs,
im not shure but i think the wood cabinet is spay painted black. could be stock also.
thats a pretty heavy transformer right there!...along with the two 6800/80V maincaps. i will up these atleast to the double uF
also visible is some sloppy selector lamp replacements, just some white electrical tape
strange looking pcb! but i believe its factory mounted
PowerAmp, the heatsink is screwd to the backplate wich is made entirely of aluminum
there is 2SB611/2SD581 TO-3´s AND 4x batwing looking trannys along with 4xTO-220 ( probably the drivers) thermally connected to the heatsink. and a thermal fuse in the middle?
and down under we find.....well the usual
also here you can see the aluminum backplate
Psu/Protection: looks very serious
that big can is a dual cap, this might turn out to be a problem once i start to make the order for parts.
some sort of modification is probably required to accommodate 2 regular caps
more relays
upper half of the pcb must be the phono stage?
