Does the CD67 have more room? I had lots of room for four Nichicon 4700uF/35v FX Muse caps in place of C803, C804, C805, and C806.

Regards,
Dan

Hi Dan,

I'd need to look inside to remind myself which is which, but in the CD67 there are very large spaces for two caps, which sit before two regulators. In the 63 they are smaller 470uf Elnas, and in the CD67 they are 1,000uf and MUCH larger in diameter, from what I remember seeing... That might explain why those two are impossible for me :-( I did put in two 1,000uf 25v Black Gate standards, it sounded better, so I'll leave those two alone.

The new caps and soft-recovery HEXFRED diodes were my latest mod and I can't really hear a difference. But, this is not deterring me from moving on.

Dan

Its a shame those diodes didnt make a good improvement - maybe they need to be Schottky types for the improvement I heard. To be honest though, when I changed mine I also put in a mains filtering cap, perhaps this accounts for the main change...

I changed mine to shottky types, but can't say I hear any difference...I've done some other mods too that didn't make any difference, but maybe all these little unnoticed changes do make a difference put together or make other tweaks give its full potential...

Two of the items on my 'to-do' list is an IEC socket and some sort of mains filtering. As far as mains filtering goes I hear alot of references pointed to Jon Risch's website.

Dan

An excellent point! That's the primary reason I'm going on.
