i'm not typically in turntables, but i got this one from my aunt who passed away. Today i had nothing to do so i decided to see if it worked. It didn't. So i decided to get my hands dirty. I like blindly trying to repair old stuff. Please forgive me if i've made major mistakes, you know, in case this turntable turns out to be an oldie-but-goodie some of you are dying to get your hands on. anyway :
-The platter was not turning, and by the look of the taper in the platter, i thought the center spindle's brass and steel parts must actually be a bearing, but it was seized. Trying to spin it with two vise grips seized., so i undid the screw, completely saturated the thing in wd40, and set fire to it for a few minutes. I started being able to move the darn things, and could remove the shaft. And then after more wd40, the steel ball that sits down there came out too. i thoroughly cleaned the bearing surfaces with soap, alcohol, then put a hearthy dose of sewing machine oil in there, and reinstalled the thing. now when i set the platter in motion without the belt being engaged, it'll run for minutes. first victory.
I then lubricated the places that say LUBRICATE ME!! (the two tubes and the four ports of the motor) with sewing machine oil (is sewing machine oil even ok for turntables?)
now for the electronic part. it sounds fine... good even. however, intermittently, and more often when i just turned it on, i hear damage-your-speakers short-like noise (kinda like what you hear when you plug in RCA cables hot, or worse, touch them to one another. I did more tests off the phono preamp (directly in my amplifier, so the speakers wouldnt hurl their cones in my face) but couldnt find the source of it. i tried to ground it to the preamp ground terminal, to a power-bar's ground pin, to my home's water pipes, and tho it seems to kinda change things, the problem is still there.
everything inside seems to be connected fine, but it's hard to look between the soldered ports in there and the arm. i do know that removing the head-with-the-needle doesn't Help it.
So far all i could think to try is make sure nothing was touching, and i cleaned the copper springy-things contact that..(seem to short the sound circuit so there's no sound output when it's not on?) ....however there IS very faint sound output when it's off... I'll hear it if i try to see if there's music stored in my fingerprints. (yeah. sorry if that's another no-no....
I'm out of a clue. Anyone got one for me?
also there's a kind of hook thing on the left of where the arm is anchored. i can't for the life of me figure out what it's for.
