I inherited an Oracle Delphi MK ii from my father as a basket case upon his passing. After replacing and restoring the Micro Seki tonearm and replacing the broken needle Sumiko Talisman cart with an Alchemist, swapping power supplies and eventually the PS Audio moving coil preamp the TT was working great for a while.
Then it started slowing down… and down. Kept adjusting and would find it had some wild swings between 31 and 36 rpm. Different every time I turned it on. Replaced the belt, cleaned the platter etc and have not resolved it.
To point me in the right direction, the motor decided to start making a cyclic “scrubbing” noise all of a sudden. So, I pulled it all apart hoping to be able to clean and oil the motor. No luck. Sealed unit mounted to a board.
In playing with it, I unscrewed the bottom graphite slot head screw on the motor and it came to life, spinning smoothly and effortlessly.
Reassemble and it was able to be adjusted to perfection. Listened to a dozen records in the last three days and was very pleased with myself, but now it just stopped turning altogether and when coerced into moving it does so slowly and with lots of scrubbing noise.
I assume the motor has spun its last record.
Are there any sources for used Oracle Delphi parts, or a direct replacement motor? I’m handy, but not knowledgeable. Oracle wants $2300 for an upgraded motor which simply isn’t in the budget.
Thanks in advance.
