Preferably a compact unit that can be concealed at the back of a rack (not enough space for frontal display).

Need an MM unit with Gain of at least 42 to 46 dB, for low output MM cart. If the stage is both MM/MC, that would also do just fine.
 

BUYING, SELLING or TRADING indicates your automatic and mandatory acceptance of HiFiVISION.COM Trading Rules and Guidelines!


Do not blindly trust every seller or buyer! Protect yourself by following the below safe trading tips.

Safety Tips

For Buyers

  1. Always meet the seller at a safe location and inspect the item before purchasing. Following this one rule will help you avoid most scams.
  2. Watch out for unrealistic offers. If it appears too good to be true, it probably is. Unrealistic offers are used to motivate purchasers to make hasty decisions.
  3. Always verify the seller's credentials. Ask the seller to provide a photo ID and proof of address.
  4. Ensure that the product you are buying is not stolen or fake. Always ask for a purchase invoice.
  5. The best way to transact is to collect the item and pay at the same time. Never transfer funds or use a debit/credit/atm card to pay someone you do not know before collecting an item.
  6. Ask for clear information on condition of the item, price, payment and delivery method.
  7. Use only those payment methods that you trust and are familiar with. Never give out your financial information.
  8. It is recommended to purchase items directly from the seller.
  9. Always test the functioning of the item before purchase.
  10. Do your research on comparative prices for the product.

For Sellers

  1. Try to take the full payment at the time of the delivery. Remember to use a safe location to meet.
  2. Watch out for fake currency and money orders. Be aware that banks will not honour fake currency/money order and will hold you responsible for it.
  3. Verify the buyer’s credentials if necessary.
  4. Ensure that your product meets the features you list in your ad to avoid any misunderstanding with the buyer.
  5. It is your responsibility to prove that the product you are selling is genuine and not stolen by providing the necessary proof of purchase.
  6. Do not share your financial information except the one required for payment.

Sorry, Techniecal, but the Pyle does not have the required gain, from what I can see in its tech specs. Also, basic entry level. Regards.

Learned from omishra that the CNC phono gain can be increased by 2-3 dB by swapping out one resistor per channel, without affecting noise figures, etc. So you can have circa 43 dB gain.

The rest you can get from your line level preamp;)

So, what I'd need is someone who might be willing to sell me a CNC stage, with the resistor changes to increase gain. Anyone?

What is the output voltage of your cart? Let me do some calculation to figure out if 43 dB will drive the next stage sufficiently.

2.5 mv output. My amp outputs 36 Wpc, and my speakers are 86 Db sensitivity. Both Cadence. Which means that with a 40 Db gain phonostage, I have to keep the volume knob at 1-2 o'clock position to get reasonable volume levels. My iFi phono does have 46 Db gain, but toggling between MC and MM involves too many dip switch changes that makes it a pain every time. Need something a lot easier to keep both TTs running seamlessly.

I use Pearl 2 phono for MM and for MC cart just insert SUT at the input of phono stage. And cranking volume control does not seems be issue until it could send amplifier into clipping at max volume.

if you just want gain (and noise is not an issue), just plug in a modified Simple preamp (with the resistors adjusted for whatever gain you want)

if soldering is not your cup of tea, try asking these guys if they have any left

I bought a power supply board from them on ebay, and i cant find their listing for this now

For 2.5 mV output optimal gain is 42 dB. This can be achieved by tweaking CNC gain.

That's really interesting Jo, can you share some more light on this? I too am looking for more gain :)

Thanks for your offer, but because of the gain issue and other aspects of the CNC, am now looking at other options. Regards,
