1980s ADC DD Turntable in exchange for postage and donation to Special Effect
ADC semi-automatic 1600 DD complete with arm and cartridge but no lid.
Purchased by me in the mistaken belief, as it turned out, that I would be able to scavenge the tonearm base for use with an ADC LMF-2.
Condition is good and the turntable spins up as expected. Strobe and speed adjust control works as it should. Movement of the arm from its rest actuates the motor and switches it off as it move into the run-off area.
The fitted arm bears a striking similarity to the ADC ALT-1 and comes with a fitted ADC QLM36 cartridge and stylus (not tested by me or checked visually for signs of wear and, realistically, likely to need replacement). The arm moves freely and smoothly in both the horizontal and vertical direction and exhibit no signs of play. The original arm cable is present and intact and connects to the internal tonearm wires via a tag-board in base of the unit. The quality of the cable and terminating RCA phono plugs is mediocre and it could easily be replaced to, I'm sure, good effect.
It is my understanding that the motor and control electronics, and possibly the mechanism too, were sourced from Panasonic. Removing the base revealed all PCBs and components to be in , given the units vintage, in remarkable conditions with non of the usual signs of ageing, consistent with the turntable having been subjected to only modest use and careful storage in its lifetime. All the gears, cogs and levers are intact, lightly lubed (none of that dark dessicated and sticky residue) and freely moving.
By far the least satisfactory element of the turntables design is the plinth, which is light, resonant and made of plastic.
Obviously, and subject to the caveats mentioned above, the turntable could be used 'as is'. IMHO, however, it would make the basis of a good project in which the original plinth were discarded and replaced with one of more solid construction and visual appeal. From I saw when inspecting the underside of the plinth, the motor, and semi-automatic mechanism all form part of what is effectively a sprung sub-chassis and could be removed with out difficulty, as could the associated electronics and switches. Yet another option would be to salvage the arm and ditch the remainder of the TT.
As is evident from the photographs, the unit has already been prepared for shipment and hence the motor spindle does not project through the platter, which has simply been placed on a supporting polystyrene block for effect.

Based on what I paid for the unit to be delivered, a prospective purchaser (I will pack the unit but not arrange for its delivery) should be able to arrange shipment for around £10.00. Alternatively, it can be collected 'in-person' between Jncs 14 and 17 of the M4 corridor by prior arrangement.
I understand that sale by auction is not permitted on the forum, but urge any potential buyer to offer a generous, albeit comparatively modest, donation to an unusual and deserving cause.
