Haha, that pitbull logo rocks

Btw, I got my clone up and running! The whole 8 volt problem was solved with the help of audio1st. Thanks.

I also got to replacing all the caps that are in the pdf, but the small ceramic one. I also replaced two caps in the stock power supply, and the results is great. I`m getting loads of detail and much more air.

I`m still also using very el cheapo metal film resistors at the digital out, hope replacing them will add to the sound also.

Default How about this one?

Probably I jumped into this thread too late, and cannot get hold of any JVC RC-EZ31/32/51 Boombox...

I found this model on www.bestbuy.com:

http://www.bestbuy.com/site/olspage....=1181831574036

will this shelf system a potential candidate for similar mod as well?

Thanks a lot.

His link works fine, perhaps non USA IP addresses are blocked.

SteveSun:

The unit in question is a Philips and I would doubt it has the Sanyo mechanism and chipset.

Many of the Canadian members here are still able to get their hands on rcez31 models and have helped members here in the USA. So perhaps just ask some of them..

The rcez32 will also work extremely well, but is considerably more work. This is the model I used and I am beyond pleased with the performance. This model is pretty rare here as well, but I was able to get a couple of them. (See my contributions to the thread on the '32 if you are able to get one.)

Anyone tried:

http://av.jvc.com/product.jsp?modelI...thId=16&page=1

the CD transport part is the same as 31, however, the chipset is consisting of:

1. Silan, SC9641
2. Silan, SA9614
3. Tecsend TS2501

and other 2 chips. Looks like they replaced the chips by some chinese made ones on main PCB...

Is this transport usable for similar mod?

Default I2S Please...

@ All, been reading the threat with lot's of interest and on the Dutch forum with Erik, very nice job.

Getting ready for the upgrades and am looking for a nice NOS DAC for use with this clone.

Now I'm getting pretty serious for trying the dddac without the Spdif unit. Directly to the I2S on the chip. Is this a possibility?

It would reduce jitter, save me some pesos for a better upgrade and better sound quality.

Please help me, and keep it up!!

8V is connected right after choke L901 (the choke is recommended to be removed).

There is also 5V supply, based on Q902. If you want to use one super regulator you should probably start with 5V supply; in that case remove transistor Q902 and connect 5V wire from regulator to collector pad, the ground from regulator connects to negative pin of C916.

I just want to report that I tried this method of connecting a separate 5V supply but couldn't get it to work. The disc would spin for a while but when it stopped the display showed zero and the disc wouldn't play.
