The last last thing....
The cartridge is NOT 66-1 or any ceramic 66xx (66-TY, looks the same as 66-1). Starting from the fact it is not aluminum but white plastic and the shape is totally different and the pins are arranged vertically one over another, not horizontally.
I guess this is also the reason they changed the wire clamps.
I have an itch to fix this but so far it's been a freeby and with this a cartridge is anywhere from 96 bucks at Turntableneedles.com to 35 bucks for two in this auction

but ine is oxidized and the condithion, even if it is NOS, is unknown.
PS. Just thought of it....I have plenty of receptacle connectors contacts that crimp on the #28-30 wires and are in fact the same material and thickness (berillium copper and are even gold-plated) as the turntable head connectors that go onto the cartridge pins. Some might fit the pins of the adapter cartridge. If this works I will 1) try to fit the contacts 2) try to yank the wires, crimp the contacts on, 3) hopefully throw away that mess of push-ons that create problems, plus eliminate thet soldering mess and black tape. That would be a final touch on otherwise fully working TPA-1, short of buying a new needle or cartridge (which I leave to Tim to do as this might get a bit expensive).
