Opening up my equipment that is.
Only thing it does is make me want to change things in there.
Next I would like to change the caps in the power supply of both my CDP and amp.
let's start with the amp
Well, it sounds really nice. Most of all i found the close proximity of the transformers very disturbing. On the other hand - sound is nice...
Since I do not listen too much anymore to my speaker system I think transplanting the internals of the amp into a custom build housing is not going to happen.
So, why not change the diodes to ultra fast and the caps to better/higher capacity ones?
Can anyone shed some light on the green drop style caps shown below? Please note the input selector hanging loose and normally sitting behind the front panel and looking like being sourced out of some vintage military equipment Alps blue poti though.
For the CDP it will be also new caps and diodes in the PS part.
The top right part (where it says CDLP) is inactive at the moment. It is the headphone out section that was fed by the tube buffer. I will disconnect the power supply to it as well.
The bottom centre with the white block thingy that has JZC 7FA printed on it(transformer?) is the first mains filter stage after the ON/OFF switch. lines go into the JZC 7FA block and to the large trafo which supplies all kinds of current (2.5V, 5.0, 25V, 220V or so) to the rest of the board.
Panasonics might be the best choice for all the above. Not sure which ones for the biggies in the amp at 450V 470nF 108deg.
