ok next up the phono, went to power it up on the variac, instant 3 amps at 10v, opps thats not good. pull the phono out and the motor coil is all toasted melted etc. guess that is what blew the fuse. the motor armature was seized up. pulled the motor and tried the turntable by hand, spent a couple hours finding out the issue there (it would not cycle properly) one tine little arm was out of place and the spring goofed up. after lubing and check reinstalling the spring is cycled correctly. Good thing too, there was a zenith TT on ebay with a starting bid of 1.99, the shipping was high but what the heck, well next thing you know the dumb thing is over 40$ bid and one day left. Needless to say there is no way I will pop for 70$ plus (inc shipping) for a cheezy zenith TT. So now I have to get this one fixed. I am pretty sure I can get a replacement motor (one of those induction motors with the stepped shaft that drives and idler pulley) from my local vintage guy (Dennis at radio relics) or Sky junk suplus. the issue maybe how to get that stepped driver off the shaft. It looks to be pressed on, too bad it did not use a set screw.

anyhoo I know the cart works (spun a record by hand) so I will deal with the motor next week.

I prob should have started with the TV at this rate it seems like it has to be easier that this TT (all automatic TT's were designed by the devil himself IMHO).

I would like to have know the failure sequence when this thing went bad. As badly as the motor is toasted I am suprized the fuse would not have cut it off before it melted down (it still had the orig fuse in, blown but in).
