JVC/ Nivico SRP-471E-3

Looking forward to seeing it! Mine is spinning as we speak. Amazing thing about this table is its isolation properties.

Thanks for the info on the capacitor.....I will get on the Bay and nab one....does anyone have a problem with a hum on their turntable? Mine does hum as soon as the needle hits the vinyl. It is silent otherwise. I think that it might be a motor vibration issue. Also had a question about VTF on this table. My research indicates that this table requires a high VTF....2.5-3 grams. I tried running a cartridge that only required around 1.5g vtf and it was skipping like crazy until I increased the VTF. I did have an improvised anti-skate weigh swinging from the pendulum. Which brings up another question. How much does the stock anti-skate weight weigh and where does it attach on the tonearm mechanism.
Another issue is the headshell. I think that you need to use a headshell that is at least as heavy as the stock headshell, or add weight to one that is not. My stock headshell is a bit mangled so I have been messing with some others. I also wonder about how good a stylus you can actually use with this tonearm. I can run some pretty nice cartridges on my Elac Miracord 50h ii that I don't think would fare that well on the Nivico. I am guessing that some Grado cartridges might be okay....perhaps a Denon 103....and the stock cartridge sounds okay mounted on another headshell similar to the stock headshell. I think that it is a very handsome and unique turntable , but I am not convinced that it is a machine that ranks up there with the better idler drives unless it can handle some of the finer high compliance cartridge/stylus combinations. Is anyone running a cartridge with a Jico SAS stylus or an Audio Technica 150mx or 160ml cartridge?

The hum on the turntable can be two possibilities. One the motor mounts are shot and the motor is humming through the base, or its not grounded correctly which would be more of a buzzing not hum. Im sorry i can't offer more, but check your motor mounts. Most originals are shot by now since this is a 1969 turntable.

As far as high compliant cartridges on a high mass tonearm? Doesnt mean the turntable isnt good because it doesnt play high compliance cartridges. The turntable was designed to play at heavier tracking forces. Comparing it to the Elac is like apples & oranges. The Elac has a lighter plastic tonearm so of course it'll track lighter for the most part. The arm on this Nivico is amazing. You can find plenty of carts out there that will fit and sound beautiful on this arm.

The tone arm may be on the high side of medium perhaps.

Can't find a consumer idler drive turn table with a tone arm designed for high compliant cartridge so far. :idea:

Me either. To further not confuse things, i usually say either medium or high mass. I believe this arm to be towards the high mass spectrum as the original cart tracks at least 3 grams.

The antiskate weight weighs in at 3.95 grams further solidifying its high mass tendencies. But thats ok with me because it tracks beautifully.
 
One other thing. There is a screw in the top of the tonearm. Wrap the antiskate weight string around that lose screw then tighten it.

Good to define terms and have a reference point. :thumbsup:
 
Ok, so im around 45 hours in listening to the Nivico without touching the pitch control. So it really does hold speed very well once that big capacitor gets changed. Just checked and its where i set it before when i first got it back. At 33.4. Why do i set it there? Because of pressure from the the stylus on the record. Thats my magical speed i like to use. Lol.
 
That is good to know.....I did notice that on mine when I drop the needle on the album with the Nivico that the speed actually drops by .2 to .3 rpms. I just ordered the capacitor that was suggested in an earlier thread. Thanks for the info on the weight for the antiskate. I have been using a 4g headshell weigh that comes with some of the various headshells that I have lying around so I guess that I am good to go on that count. I looked at the motor mounts that are on the table and they have been replaced, but they were replaced with what feels like a very hard rubber. Any suggestions on good materials for this. Is sorbothane a viable alternative or is it too soft? I put some sorbothane under the turntable chasis to keep it from touching the plinth and to reduce the tension on the spring suspension, but it didn't do much. I noticed that one of the spring suspensions is not really functional and will need to address that as well. Is there supposed to be any foam or other type of dampener inside the spring suspensions similar to what is on an Elac Miracord spring suspension?
I have the original cartrdge with an OEM stylus in it that sounds okay. Just wondering what might be best suited for this table. Has anyone tried a Denon DL-103 or a Grado cartridge to see what they sound like? Maybe some of the older Shure cartridges might work as well....an M44 or M75?

Ive had a Shure M44-7 on this arm and its a good match. Right now i have the stock cartridge on one headshell and a Nagaoka MP-100 on the other. I wouldnt use sorbothane as it leaks like an oily black substance and could get into the motor ruining it. You need something softer than what you're using but harder than sorbothane.
 
So ive lived with the Nivico for a bit now, and speed is still dead on. I do get a bit of rumble with the motor, but im guessing thats normal and thats why the drive wheel is there to dampen that. This table has amazing prat. Maybe the best ive ever heard or close to it.
 
Glad to hear that it is running at steady speed. I have been playing around with mine and have decided that I need someone to do some more work on it than I am prepared or qualified to do. My secondary idler wheel is making noise when I spin it free hand. It might just need some lube, but when I was looking at the innards with the platter off and the motor running, I noticed that the main idler wheel was only making contact with the motor shaft with about a third of the idler. There is an adjusment screw that allowed me to change the height of the idler to allow it to make fuller contact. After I did that then the secondary idler wheel started making some sounds.

I still have some rumble and a hum. I noticed that what seemed to be a ground wire was no longer connected to a tab that the other channel tonearm ground wire was connected to. It is a very fine wire. I was able to solder it, but I am still getting some hum. The RCA connects have been replaced previously and I really don't like the soldering job that was done there. Nor do I like the RCA connects that were used.

So I am looking around for someone who can do some of this work correctly. I do love the dynamic sound that the turntable produces. This is the idler drive sound that I have with my Elac Miracord tables. The Nivico also has a uniquely handsome retro look that I really like. Is it ever going to sound like my Mitsubishi LT-30 with a nice LOMC cartridge on it. NO..... but it has that sound quaility that is appealing in its own way that is unique to this table. It is also a fairly rare table so I am going to keep it around. I just need to get it playing the way it should sound.

Last question. There is one thing that I have noticed about mine that bothers me also, and that is the fact that the threaded sleeve that is at the end of the tonearm that threads over a standard 1/2 inch cartridge is somewhat loose and less that stable. I have to fiddle around with it to get the cartridge and stylus aligned in a true perpendicular orientation with the lp that I am trying to play. The fact that it is somewhat loose also makes me wonder if it is contributing to the hum that I am hearing. Just a thought.

Mine is tight and feels like new when i use it. The knurled knob at the end of the arm that is. I also figured out where my rumble was coming from. The bearing had some old grease on it that was caked on. I cleaned the bearing and re-aplied some new oil and now its much more quiet now. I hope you get all your issues situated, i believe this table will blow your mind.
