If you think the TT101 is mechanically and electrically problematic, think about that 40-year old vacuum platter of the TT801,
at least and fortunately the 801 only has this little motherboard and a small card for the power supply (bridge diode, regulators and filter capacitors unlike the 101 where total chaos reigns in the 2 motherboards and are decidedly more complex, making the repair
of those who must work extremely difficult.
