re: TC-270

Nice unit. Bought two for 60€ total. This was convenient to cross-check and to test some parts and exchange them to keep the best ones for one unit. Got only problems with two rubber wheels being deformed, the previous user having left the recorder on play while storing it away...The schematic was very useful. No problem with the electronics, working as on the first day. I am restoring a REVOX A77 mk4 about the same age but there a lot of work with capacitors replacement. Sony electronic parts seem to be very reliable even after 40 years. The pinch roller mechanism was slow to move in place because the original grease hardened up. Not only there but on most moving parts. I used "Kontakt IPA" to clean the stuff away (took some time) and used "Kontakt 88" to relube the parts. No need to remove the head block. The flywheel had no mechanical contact with the small rubber wheels and the motor drive but there again parts were frozen solid due to hardening of the original grease. All this was pretty easy to fix. Is functioning now as new.
