Production Years

I've seen this model number listed as produced in 1968. From when to when was this produced?

re: Production Years

Sony listed the TC-105 in their open reel full line catalog back in 1965. Production continued into the early 1970's as this model was still shown in the 1970 Allied Radio full catalog. The replacement, the SONY TC-105A, was continued on for several years into the 1970's. Primarily as an A/V unit for schools and institutional purposes. The "A" model was UL approved, featured a 3-prong grounded AC cord and plug and features a different Record / Play head that didn't require a pressure pad over that head. It did still use a pressure pad on the erase head. These models were very well built and can still provide an excellent unit for portable recordings. It is a one channel unit that uses a quarter track head so recording time is doubled as two tracks can be recorded in each direction and the user can select the track by switching the Track exchange switch position.

Got one but no power. Checked the fuse and that seems ok.
Anything else that I could check ?
Downloaded the manuals and will work through it, to hopefully get it working.

re: TC-105

mono 1/4-track deck, but easy to use and very reliable. Our church has 6 floating around, dating back to s/n 10004. Relatively few problems, given over 30 years of history with some of them. I'm curious what the starting s/n for the model was. Schematic was helpful for identifying a blown cap on the oldest unit.

re: TC-105

Have you ever needed to work on the pinch roller mechanism? I've just purchased a TC 105 and the roller doesn't move into place. It's not obvious how to remove the 'head block' to see why the roller mechanism doesn't move freely so if you know how to do this, can you please let me know?
thanks,

re: TC-105

The original grease that the factory used to lube the parts hardens up.You have to remove the old grease clean with alcohol and then regrease and that will take care of most issues with this model especially parts that are spring loaded.common problem with units that are old

re: TC-105

Just got one that's doing the same thing. The flywheel isn't turning. Have you had any success with yours?

re: TC-105

Hi just joined the group with the same "flywheel not turning" issue. Did you ever get yours to work?
