I purchased my TD 124 in 1970, and have maintained it all these years. New motor bearings, chassis bushings, motor to chassis bushingsupdated the on/off switch,and regular oiling, and it just keeps purring. Eddy current speed adjustment is right on. Mine is a 1957 model (Series I, early S/N), and the originalneon speed indicator lamp is still like new. 4.5 kg (almost 10 pound) main platter and I repadded the outer platter (lift) brake once.
I use it daily, paired to my WOPL'd 700b. I added the SME arm about 1972, and have freshened the internal rubber bushing there twice
(they dry out, and deteriorate). A little TLC is all they ask.
I have the original Ortofon arm, and cartridge tucked away. I refinished the original Ortofon plinth and armboard a few years ago.
The Series I and Series II TD 124's are classics.
