Jokeyman. I've struck a snag in the disassembly of my PX 400-r. With the instrument bottom up, I first removed the black stabilizing bar and a small 4-3/4" wide plastic panel which spans the width of the unit., I am left with the large cover panel which covers the entire underside of the instrument . It is secured by a multitude of screws, all of which I have removed (including the eight deeply recessed ones). At this point I expected to be able to simply lift off the back cover, there being no more visible screws holding it. It won't budge.... leaving me to suspect that there might be some additional screws securing it from the top. Turning the unit over, there are no visible screw-heads so, if they exist, they must be under the top back panel that houses the speakers . Problem is, I have removed both side panels of the unit and cannot see how to remove the top back panel! It can't be that difficult...I'm sure there is some simple two- second step that I'm missing! I'm hoping that you or one of your followers can solve this?

Thanks for the prompt and detailed response. I'm really impressed with the sound/tone of the 400 as well as the action of the keys. If I can just reduce the "clutter" of the keyboard somewhat, I'll be a very happy owner! Before purchasing the 400, I tried a number of different brands and models (all used) and most of them were at least as noisy, many worse. Sound-wise, I preferred the PX-400 to all of them. A very under-rated instrument. I'm going to attempt the installation tomorrow and will let you know how it went. Thank you again for your kind assistance!

Any advice from anyone....?

Jokeyman 123 I have just purchased a used Previa PX 400-R which is in great condition, except for the noisy key action. I could not find your previous Post on how to dissemble Your PX350 and would appreciate you directing me to it. I'm hoping that the procedure will be the same for my PX 400-R? ....both the dissembly and the placement/fitting of the insulating material. Are you familiar with the PX 400-R? if so, what is your opinion of this model?
