I nestled the power transformer behind the existing power switch, after relocating a few circuit boards.
The transformer was fastened to the chassis with one 6MM bolt thru the bottom.
To fit the tube output board, I had to remove the video portion of the player. This was not a problem for me as I use the unit for CD playback only.
An aluminum plate was fabricated to mount to (4) newly vacant mounting tabs….in turn, the board was bolted to that plate.
The output signals were taken to a pair of chassis mounted RCA jacks installed into some unused holes.
The sound is very good! Smooth, extended frequency response, and very musical….MUCH better than stock!
