I like your glass platter, and need to make a platter for my fixerupper. There is white in the middle of the glass platter, is it some sort of nylon piece? to reduce the hole size to that of the spindle?

Dan.

Is this the new Pro-Ject Debut Carbon Esprit SB a new model or is it the one from the UK?

From the end of Sept. the budget range will be made up of varying series of models as follows (in price order);

Elemental - New budget skeletal deck (also in USB version)
Essential 2 - Replaces previous with new tone arm.
Genie (RPM1-3) - Continues
Debut S/E - UK only (predecessor to Carbon)
Debut Carbon - Continues
Debut Carbon Esprit - UK has the S/B model only
Xpression Carbon - New model, carbon arm, new platter

There may be slight variances from country to country but this makes up the basis for the next year.

I would like to thank everyone who contributed to this forum as I am about to embark on a year long quest to find the perfect under $1,000 turntable. I use a doctor's stethoscope (available cheap at most pharmacies)to determine tonearm connection to the motor. Just touch the stethoscope to any part of the tonearm while the platter is rotating (leave the tonearm off the record of course). In the late 70's this resulted in me moving the drive motor from an Ariston RD2S into a poured concrete resin slab. The tonearm was then dead quiet. I also arm myself with an old vinyl album to see if the tonearm sings the songs without the help of a connected amplifier. They might snicker at the store when you walk in with the stethoscope but they sober up when they hear for themselves what a dismal state the sub $2,000 turntable market is in. Good luck everyone in your quest. (P.S Darko - Digital Audio Review - just went with a used Lenco so this is going to be a long journey.)

I installed the upgrade kit a few moments ago on my RPM5 and the platter is spinning much slower :cry: anyone have any idea what can be done?

How do you know it's spinning slower? It probably has nothing to do with the kit. The motor is still stationary, so unless the belt is slipping, this kit can't cause a reduction in speed.

I swapped everything and put a record on and it's playing much slower than 33 and 45 rpm. I can tell from how it sounds. They sold me a 60hz kit and the engine on mine is a 50 hz, so I'm guessing thats the problem...

The 60Hz kit was too slow for 60Hz tables as well! Pro-Ject goofed on the sourcing for it and decided to withdraw the kit from the North American market (according to the distributor here). Plus if you have the Pro-Ject acrylic platter, the sorbothane raised the motor bracket so much the top of the hub rubbed against the platter!

Yeah, I contacted the dealer and they'll try to find a 50hz kit wich I suppose has a different pulley, otherwise I'll just take it back for a refund-

I just bought a used Pro-ject Debut Carbon (not the DC). The table is all stock and was fitted with a 2M Bronze cart. Sounds great so far. Have not experienced the rumble problem as of yet. Do I need this kit?

What other upgrades do you recommend for this table? Is the acrylic platter a wise investment?

I have some 45s that I only play on occasion. Would I benefit from a Speed Box other than not having to switch the belt manually. Does it provide other benefit such as reduced noise floor?

What about a record clamp?

Thanks in advance for your suggestions.

I've had my DC around 6 months now, I upgraded to the acrylic platter, it made a big difference, background rumble has gone and everything is much more precise and controlled. As you have the Bronze fitted, you need not be concerned with my upgrade from the stock Red stylus to the Blue, others may though-again the difference was well worthwhile.

Not sure you can use a speedbox, on mine the power supply is fitted internally, I think earlier Carbons can though? I play the odd 45, and changing the belt is not a big problem, takes around 10 seconds? Biggest problem is remembering to change it back #-o

Further to the posts above on the Pro-Ject S/E belt upgrade, I found there was still hum being picked up by the tonearm wiring. The turntable is an RPM 5.1, but I have also found this on several other Pro-Ject turntables with carbon fibre arms that I have set in the past (I am a professional audio engineer). The carbon fibre arms on Pro-Ject turntables do not seem to provide 100% screening. I fixed this problem by installing Cardas screened tonearm litz cable.

Once the tonearm is was quieted down, a new source of hum is revealed. Hum is induced directly into the phono cartridge (an Ortofon 2M Blue in this case) as it approaches the centre of records. I believe the hum is being "channeled" from the motor by the metal components of the sub-platter and spindle. Grounding the motor chassis does not help, however a ground wire from the RCA interface ground to a screw on the bearing assembly eliminates this source of hum. The three mods combined reduce noise by around 20 decibels.

I wish I'd visited this forum before buying a Debut III Special Edition when I travelled to London. Definitely a bad move, because this model is 50Hz and I live in Brazil, which is 60Hz. I haven't even turned it on yet, because it will run faster. I read the this whole thread, and it was very helpful.

So I'm thinking about buying a 60Hz pulley, although Henly didn't recommend using it with the rounded belt that came with the TT.

I'd like to ask you for some feedback about this configuration in the long term (rounded belt + standard 60hz pulley). Should I consider buying the standard flat belt too?

I suggest you buy the Pro-Ject Speed Box S with an appropriate plug-pack supply for your region (18 volts DC) then you can use the existing pulley. The Speed Box generates it's own crystal locked 50Hz and is much more stable than the mains frequency used in simple setups. Plus the Speed Box allows speed change to 45rpm by pushbutton by outputting 67.5Hz when you select 45rpm. Just make sure your Debut III has the 16 volt AC motor to be sure it is compatible with the Speed Box.
