I recently dusted off my father's old turntable after becoming somewhat of an audiophile over the last year or so. Unfortunately the motor doesn't seem to function.
After talking with him about the tt a little more, it seems he bought it from a buddy in the 80's but never actually got it to work. It would be nice if he had the manual for it, but alas, no.
I've taken the base off the table and done a simple examination to insure that all the fuses are intact and that, yes, the power cord does its job. Above that, I don't know where to begin.
So, for any of you that own or have any experience with a pd277, do you have any suggestions?

Hi,
We need some photos, 277's seem to be very rare / lack of info.
DD and fully automatic is all I can find.

Here's a rather detailed set of pictures I just took of the turntable.
An overhead view of the whole thing:
The table without the pad:
The underside of the table:
The table with the pad flipped over to the rubber ridged side:
The pivot of the tone arm:
The internal circuitry:
[Note: The motor had been partially removed at this point and was set upside down and the spindle is thus viewable.]
A comment on the motor: It seems to have 9 leads for 4 coils. It appears to be a step motor if memory serves me correct.
I've got a few more uploaded, but I think this is sufficient.

Hi,
I think your going to need a service manual to make sense
of all that spaghetti. What test equipment do you have ?
Have you checked the boards for DC voltage rails etc ?
anything light up ? any power getting to the motor etc ?
