JVC tt-101 repair

Got a JVC QL-10 with a 120V TT-101. Speed is wonky. Sometimes plays fine, sometimes spins a 1000 RPM, somtimes runs forward & then backward. Could use some help.
I've seen several nice 801's show up, but none of them had healthy platter mats.  The vacuum doesn't work without the original mat. 
Hi, my trusted repairer today has given up and in a few days I will return the TT 101 (after 9 months) partly repaired and partly still broken ..... now I have to look for a repairer who knows the TT101 as himself.
