Arguably amongst the worst designs seen in Britain. Fundamentally it is the same as the VC73DA console, so read that page for the thorough slagging off.
But now I can get to more of the components, check out the 7KV E.H.T smoothing cap. Ideal for smoothing an E.H.T. that could be anything up to 9KV.
|SERVICE DATA||I've got a copy of the Trader service sheet #974 for the VT53DA. However
this is a VT53A, but I've no idea what the difference is. I thought "DA"
was DC/AC mains and "A" was AC only, but the lable inside the
cabinet shows this 'A' model also handles DC mains.
|WHERE I GOT IT||Bought off fleabuy for 50 notes and perhaps another 10 for the petrol to go fetch it ... plus another 20 in the swear box as a result of using the M6 both ways during peak hours.|
|A very compact chassis. with all the big bottles almost butting up together and helping to keep the line output transformer, which is in the middle of them all, nice and warm.||The underside looks a bit sparsley populated but most components
are in the sheilded box on the right. Not exactly good for the service engineer
but probably essential to maintain stablilty in a backwards ye olde T.R.F.
receiver as opposed to a a superhet system which had only been in widespread
use for 15+ years.|
Usually after 50+ years wax caps are half melted blackened blobs but the ones here (yellow things, bottom left) are pristine. My bet is that they've survived because:-
