Long story short,
fallen in love with the Oracle Delphi since I was a teen (and that was quite a long time ago) but could never afford one, a couple years ago I went to visit a friend's whose dad was a passionate hi-fi collector since he wanted me to help him to sell some of the stuff which is a lot and which nobody is going to use (the dad passed away a few years ago and the wife doesn't make any use of that gear); among all the stuff (4 pairs speakers, 2 AR preamps, 2 mono power amps, Sansui pre-amp, phono step-up etc) there was this beautiful JA Michell Gyrodec in its first incarnation and even tho to me is not the Delphi I am still in love with still it does a beautiful object and, probably, an even better sound machine than the Oracle but it took me over a year to get in possession of it along with an Audio Research SP9, the Kiseki step up and three tonearms, a Zeta (which is going for sale since it needs to be re-wired and am not into that), a Rega 4003 and a Linn LV X which is at this moment installed.
Took it all home very excited, it all worked but needed rejuvenating, in this first instance I want to concentrate on the Gyro which needs new belts, new pick-up wires and to be set up.
Originally there were two arm plates and the motor was in the front left corner, I don't like to see the empty base and the motor wire running below the plexiglass base so I restored to single arm by removing the arm base and putting the motor back in there, applied the extra weight at the bottom of the frame and that's it but, so far, I have many doubts.
First, the tonearm doesn't look well placed, it probably needs to be raised and aligned (please need your guidance), the frame balance also needs to be adjusted, the base of the motor actually sits above the frame and from the pics I see online it shouldn't be like this, it might easily be solved by tuning the springs but even here I need guidance.
This would be enough to start and to put it back into working conditions, every hint will be greatly appreciated.
Grazie
p.s. I know the Linn LV X installed tonearm to be the worse of them all and the Zeta the best but my guess is that the original owner had to rewire the Zeta (I can tell since the wires are broken after, probably, a failed cartridge installation) as well as the Rega (which I guess being the one the turntable came with since it is Michell branded with model number 4003 which I can't find as an original Rega one) which also needs to be rewired, probably this would be better than the Linn but my priority now is to put it all back into working conditions by not spending extra money if not for needed parts (pick up wires and belts), eventually I might restore the Rega if I menage to sell the Zeta but not a priority now. One extra bit of information, as you can see from the attached pic, the motor pulley is the one to fit two belts.
