Project: Restoring a Reel-To-Reel Tape Player/Recorder: TEAC A-3440 - New set of plastic feet installed on the unit.

You can see in the previous post some pictures of the unit, and you can see that it is missing its feet. You can also see the picture below to understand the problem:


There was also missing the feet from the back panel:


I would like to show you below some of the side effects of not using the factory feet, beside stability issues:



The wood panels are scratched and chipped at the bottom.
With help form a friend from United States that is supporting me with parts or equipment hard to find in my area, I was able to find a complete set of feet, you can see below:


At the end my Teac A-3440 looks like below:



One of my next tasks will be to repair the power cord strain relief, the present one doesn't look to good, and I will do it as soon as I will be able to find the original.
