@noromance Brian, Call George Merrill. He sells Jelco. He may have some left.
There's a 10" 750 for $610 on eBay.
Audio Sensibility have the Mk1 850S 9" for $1100.
Don't spend $1000+ on a 750.
Thanks, much appreciated. Yes, I need a 9” arm to fit the 214mm center to spindle spec of the table/armboard I’m purchasing with a 30mm hole.
And USA HIFI has the 9” 850 MKII for 1,260.00 That Is doable, and also carry the DIN cables.
