That's why I picked them, they are superb on clock psus as well as pre reg smoothers on analogue psu.

One of the best uses for these (or similar) is the +10V (raw) rail in the CD63.

Well... this might be just what I was looking for.

What about the -10v rail... can we benefit from upgrading the cap before the main +5vreg ?

I usually fit a 16V 4700uF Pana FC for the -10V rail. Fitting the 22000uF onto the pcb for the +v rail takes up a bit of room and leaves very little for the -ve rail. The +v rail is under much more load than the -ve rail too.

There are many spam about "get it 2 inches bigger", it's audio caps?

Default coax mod

Hello all.
What about coax mod between Dac and decoder, and eventually for HF signal path?
I'm looking for some "Know how" about it.
Thanks.

Back when a cd63 was my main music maker I had a coax run doing the HF signal from the mech board to the main pcb. It covers quite a lot of ground and saves the signal from going through a lot of pcb traces and a connector or two.

It makes the sound a lot more analogue, removing harshness and grit. Some call this type of improvement a reduction in digitalitis.

Someone on here will remember, or I can look at the service manual later, just leaving the office now! I think the receiving end is R501 but would have to check...
