Roland S-50 - Front Panel Repairs - Restoration Part 3

Part 3 - The Roland S-50 restoration continues. In this episode we are looking at the issues with the front panel switches and if we can see any obvious problems with the vacuum tube display that is fitted to this instrument. While I have been using the Roland S-50 I have noticed that a number of the front panel switches are hard to operate, including the 'Shift' button which is used to confirm most of the operations on the keyboard. It is a false economy just to replace one switch so all 30 plus tack switches will be removed and replaced with the new equivalent part. I have also gone for switches that require a little harder force to activate as these will be more durable. The display is going to be a very interesting problem. It is a vacuum display that was incorporated on a number of Roland instruments of this era, thinking specifically of the JX-8P. There is as far as I am aware no modern replacement. So we will need to have general look at this one and figure out can it be fixed or is it foobarred. Background I acquired the Roland S-50 a few years ago after I had been on the hunt for a low-fi sampler. This fitted the bill sampling at 12-bits. Not only is the Roland S-50 a fairly useable sampler, Roland and many other software / sampling vendors also crafted sample sets for both this and the Roland S-550 / Roland S-330 platforms. When acquired there were a few problems. Apart from the sampler being filthy, some keys either did't work or work intermittently and the screen randomly choose not to work. What I didn't know when I started this project was how involved it would get!
