I sent a TT101-specific Integrated Circuit chip to a fellow enthusiast in Germany for repair of his own TT101, and he informed me that my chip worked to salvage his unit.Thankfully I remembered that Lew had 'cornered the market' for the only unobtanium chips used in the TT-101....so after 6 months of stalled frustration......Thuchan's 'junk' TT-101 which I had found for him, is now operational.
And after the complete re-build which his Bavarian craftsman has performed.....it may well be the best TT-101 in existence.
I've offered to buy it from him should he not like it...👅🎼
