Marantz CD63 & CD67 mods list

[Malefoda]

Well they are like advised before Black Gates Standard, 220µF/16V instead of Elna RJH 470µF/24V + 100nF PPs bypass.


I did also removed the headphone section and the 12V lines at that time.

Remember I've all the Ray's older list on, 12V Raygulators and 0.22µF Wima MKP between pin & 8 at each opamps and nothing around the 5V lines. (still the 7805, better one as Ray's advised then).

Today I've moved (froward or... backward...) in touching my integrated amp, pre amp section. It does no good to sounds, anyway the new caps may burn in some I guess.
For the work done:

Maybe the 0.22 wima are causing this. I find bypassing BG to have a negative effect.

I think he means .22uF mkp between pins 4&8 @ opamps. But I have been wrong before...

Yes Brent, Lee is right, the MKS4 Wima 0.22µF bypass each Opamps at pins 4 and 8, but maybe they also do something to the sound anyway?

I never had a problem with a cap there, in fact it either made a good difference or non at all.

I'd say that you're hearing deficiencies elsewhere. I'd try giving dac analog its own reg and see if the sound evens up.

Matthieu, try reversing the latest "upgrade". If you like the sound more with the former components, then stick to them.

If you like the sound of Elna's more, then they are better, in your setup.

Remember, always trust your (own) ears.

Yes AVR, but it's more work to undo... I'm lazy! I let the stuff burnin' in the whole week, and make my mind next weekend.

Sorry if I stepped onto someone's toes, it's wasn't the plan.

I just wantet to say, that we have to remember, that we are individuals - with different hearings. That's makes the whole thing interessting.

I completely agree. I went to a mates house the other day and listened to his £1000 Ruarks after hearing him say they are fantastic. They're too bright for me, but he loves 'em.

It must be hard to be a hi-fi journalist, giving descriptions of a sound when someone else may think something completely different.

Anyway, I'm now stuck without a cd player for a bit as it keeps blowing the lm337's in the discrete regs

Hi Lee

I have been reading your posts about this dac analog reg and you wrote "Put FC + 7805 on small piece of stripboard, solder on some legs and then feed the output straight onto u199 (remove u200)"

I replaced Q811 (7805) by a LM340AT and I got fantastic attack and overall body of the sound.

In this case can I expect improvements by using a 340 instead in the dac analog reg that you preconized ?

Best regards
