Are you familiar with a highly viscous, clear "fluid" substance which, when applied to the cassette door hinging mechanism, slows the speed at which the door opens?Many, many years ago I was in the electronic service business and authorized Sony among other brands. Back then parts support was about 7-10 years depending on the company. Sony is currently using a third party company for parts distribution.
Here is the current list of parts they have available.
Sony TC-R303
I quickly looked and did see few sketch sites with service manual scans (beware of strange pop ups). If you can confirm one of the parts listed is one you need, great. Otherwise, it would be unavailable. Next option would be Ebay to purchase a parts machine.
Sony specific? Sony had a lot of specific service products. I still have some of the special drivers used for small camcorders that just fit where SAE drivers are sloppy. A lot of the metric is ISO.Are you familiar with a highly viscous, clear "fluid" substance which, when applied to the cassette door hinging mechanism, slows the speed at which the door opens?
Damping grease aka high friction grease. McMaster Carr or Amazon if you search high friction grease. Higher end equipment had mechanical dampers.I can't say if this was Sony specific. I had a buddy who was an electronics repair tech for Sears back in the 70's-80's. I was in his shop and he showed me a cassette deck he was working on. He pressed a button to open the door and it flew open with a bang. Then he pulled out a small bottle of what looked like clear water, but the "water" didn't move when the bottle was tipped. He used a toothpick to apply a small drop to the bottom corners at the door's hinges and closed the door. He opened the door again and it glided very slowly to the open position. It's always puzzled me as to what this stuff was. I kind of assumed it was widely used.
eBay has a couple units you could use for parts, but the shipping is almost as much as the deck.Hi i am new here , but was wondering if anyone has an idea where to look and find a cassette door for a sony TC-R303 has a broken part in it was purchased used but just trying to fix it up .thanks for any help.
