Marantz CD63 & CD67 mods list

[Fidelity Audio]

On a lighter note.

My players browndogs are now fitted with BlackGate NK 0.47uF across +/- rails and 2x BlackGate 10uF from + to gnd and - to gnd via a low loss earth wire to star earth.

Its sounding very good but as usual will test over weekend.

I will also posts pics of this mod after weekend as i'm sure some of you will laugh.

Hey

I have been measuring voltages on my dead 63 today and have found out that the lines supplied by the glass resistors FH11/12 are dead. I can't get any voltage readings from these resistors or anything else after them.
My question is, when whatever blew around QM01, will it kill the voltages supplied after the component that blew, and still leave a circuit so that voltages can be read before the blown component.
I'm just wondering if it would be obvious that those glass resistors had gone, and should i get another pair? Which ones do you recommend i get if i do need them, and can i get them from maplins?
I ask, as im not sure if they are quick or slow blow, and what exact ratings i need other than what is listed in teh service manual (1.6A, T630ma?)

They are fuses not resistors LOL.

The T in T630mA means they are time lag and they are 630mA fuses.

I have 1amp in mine as the 630mA blows on power up due to the demand from caps lol

Yep that's what i ment, i knew they were fuses. I do sound like a dummy sometimes

OK cool, il probably order some 1a ones. But i was wondering, is it likely that they have blown, causing no voltage readings from anything after them, or would any of the blown (smokey) parts that blew around QM01, automatically produce no readings throughout.

Il try and simplify.lol. If a resistor around qm01 blew, would i still get voltage readings from the 5V reg (Q811)?

cheers

Do you know where the smoke came from???

Pretty sure. I'm not sure if it came from QM01 itself, or one of the components just above it. Still, would that totally screw up the 5V rail or will the blown fuses have prevented me from getting any readings ?

p.s. im recieving the player off josh, you cheeky so and so

Don't put 1 amp fuses in mate. I only put 1amp fuses in because mine was demanding 920mA.

If you have a fault and you fit larger fuses you can cause more damage.

O right. I guess youput the 1A one in because of the vast number of additional components and caps you have put in. So il stick with the 630ma ones.

Yes do that

I did a typo too.... the mA was 820mA.

So, what does the radial servo do?
Its shocking the number of issues we're suddenly getting.
