New JVC 4DD-5 Delivered Today!!!

[Q8]

I am now the proud new owner of a brand new (old stock) JVC 4DD-5 CD-4 Demodulator. It was fun opening and exploring the box for the first time. It even smells good.

The CD-4 adjustment record has an ever so slight warp. I've seen people say that before about these new old stock demodultors I imagine it will be fine. It is otherwise pristine.

Now all I gotta do is get a proper cartridge/stylus together and I'll be in business.

I'm glad I went new instead of used with this. It's nice to be the first userand be able to unpack it.

I've had mine for a few months now, and it works really well, though I suspect that it will get better as it "breaks in." My record was also warped, and I had a difficult time adjusting the separation as a result, so I just used my Fisher disc and I'm good to go. I also have a Sansui adjustment record for my QRX-6001. The 4DD-5 is every bit as good as the Sansui demodulator, BTW. Have fun with yours! Oh, I almost forgot, I just got a sealed CD-4 disc of Godspell Original Broadway cast recording from eBay. I'm going to listen to it tonight!

So the warped record caused issues setting up the seperation? (I have not played with mine yet as I am still deciding on a cartridge setup) How warped was yours? Mine only has an ever so slight bow. I was thinking that the warp should not be big enough to effect the seperation. Especially since I'm going to be using a linear which should track the groove pretty well even under non-perfect conditions. If a slight bow in the record (and I really do mean slight) can cause issues with setup. I may want to seek out another CD-4 adjustment record soon.

And have fun playing that Godspell record for the first time. Should be pretty ideal conditions. New record. Fairly new demodulator. I have a used copy of Black Sabbath Paranoid on the way, plus I have some other discs I've been collecting for the day I can play CD-4

Actually, I misspoke. My issue was getting the 30kHz carrier signal properly adjusted, and my record was very warped. So much so, that I just couldn't make the adjustment fast enough, and I had a "gritty" sound that I was able to get rid of once I used the unwarped disc. The Sansui disc I have has a slight warp, and I had no problems using that on my Sansui, so the degree of warp seems to make a difference.
