Restoring a Commodore CRT Monitor 1702 - Featuring Commodore Video! | The Perfect C64 Display.

In this episode I do a complete restoration on Commodore 1702 CRT Monitor from 1984.  This vintage video monitor was purchased by my client and then mailed directly to me from an eBay seller.  This CRT needs to have all the electrolytic capacitors replaced.  I will need to create a custom capacitor kit.   Please join me as I future-proof this lovely piece of vintage computer hardware.
