This video relates to my purchase of a Hewlett Packard HP 3582A audio spectrum analyser and it's repair and restoration. This video was going to be cancelled due to a lot of it being focused on the creation of a dual axial capacitor board which turned out was not needed. Also the video covering the replacement of the input binding posts and cleaning the inside of the clear perspex cover was los...

Video describing the process of adding a master volume control to a Fender AB763 amplifier such as the Deluxe Reverb, Vibrolux, Twin Reverb etc. I explain how the AB763 circuit works from the phase invertor to the power tubes and how to implement a master volume. I then install a master volume and re-bias the amplifier afterwards.

This video is a demonstration of the method I use when disassembling devices and then have to re-assemble them at a later point in time. I will be using the same technique in future videos so watching this will allow you to follow the disassemble/re-assemble maps that I create. The victim for this video was a Samsung NF110 which I happened to have lying around in the lab. There will be many fur...
