Urei phono cards now available

I've built some customized Urei phono cards using precision components and a modified circuit featuring a Burr-Brown op-amp for the main IC. The sound is more pronounced than the original phono cards and maintains the full sound spectrum.

Just to be fair... Consider this product like you would Cherry Coke to Coca-Cola Classic. This is a derivation of the original for those seeking something a little different than the norm.

Please feel free to contact me for more information on purchasing, or distribution. Mention the Wave Message Board and I will be sure to grant a discount.

Best Regards, David

I like the film-type caps in parallel with the electrolytic coupling caps on the outputs :-).

How much are we talking about ($)?

For Wave Board users the price is $100 flat, so long as you mention the message board. Otherwise the retail price will be $125.

cool...seems very reasonable to me (assuming the performance is there, of course). I'd guess the noise-floor is a lot lower than the original TL084-based circuit.

Guess there's some haters out there.

Ebay yanked the auction due to some "word spamming," so I've relisted with more careful grammer. Opening price is still $65 as before.

I can't wait to try these out on a proper club system. You'll get a full review on my cards vs. the originals in another week or so.

Hey Dave,

Neet looking thingie ya got there. I suppose if I were to upgrade my 1620 it would have to be all three phono inputs so they sound the same? How do they sound compared to a Rane PS-1?

Got one kind of tech-weenie question that comes to mind after looking at the pics and remembering a couple of experiences I've had...

Are you using film-type capacitors on the power-supply rails on this card? If so, you might want to change them out for some good-quality ceramics...I've had a couple bad experiences with trying film-type caps on power supplies. It seems that the typical failure-mode for film-type caps is to short, whereas ceramics tend to fail by going open. You could therefore knock out the whole power supply in the mixer if one of the film-type power-supply bypass caps fails (if that is in fact what I'm looking at in the pics).

Whatever the case, I plan to pick up a couple of the cards when I start on a Urei restoration project in a few weeks.

Mark:

Sorry I didn't respond to your post re: the caps. The film caps are in the voltage stage in parallel. So if in the rare and unlikely instance that they burn out; they will not short out the circuit. They are rated at 50V which is far above the +/-18V of the phono card. They are only there to help smooth out the current since the quality of the electricity greatly affects the sound.

I've been running a card on my turntable day in and day out with music pumping and so far so good.

___________________

Every resisitor is 1% metal film; every capacitor is 5% polypropelyne film (except for the coupling caps); the Burr-Brown IC has been carefully chosen for its speed and accuracy; each IC is individually tested prior to assembly; each board is hand soldered to ISO-9000 standards; and each board is tested and burned in before its considered for shipping.

So in conclusion you will most definitely get the same sound from 1,2,3,4,.....,N phono cards. The original cards have 5% carbon resistors which will surely guarantee a level of deviance from one another.

As far as compared to the Rane PS-1; the grand supreme phono pre-amp; I think you should try it yourself and draw your own conclusion. I invite you to purchase a phono card from me and test it against the Rane. If you don't like it, then send it back to me in working order and I will refund your money less shipping.

I am not familiar with the PS-1 and cannot say that I am acquainted with any of the Rane equipment.

high end urei replica phono cards

They are coming here, Im getting two of them. They should be good as Dale 1% metal films, polyproplene caps and especially the Burr Brown IC are said to be the very best available. If they sound like they look Ill be saying it loud and clear.

And if they are good they are good, and is a very cost effective and easy to install upgrade!

That is all.

Re: high end urei replica phono cards

Dave,

Nice job, looking good. I would also like to take the pepsi challenge or coke (lol). I tried the Burr Brown opp amps and heard no diff. I would love to compare your cards to stock card. I have seen 10 to 15 diff. phono pre amps, some great and some I would run over. If the card is good I will give you the 5 star rating.

HAPPY HOLIDAYS
MARIO G

Hand delivered

dave hand delivered the phono cards to me today and I will install them on Monday. After a full week of listening to them with every kind of music I will then post a detailed reveiw.

On a very positive leading note, they look great, solder work is as neat and professional as IF these had come from a really good manufacturers!

I figure two days of break in time, then a week of playing music, and then I should have enough to say about them!

I'm curious to hear any reviews on these cards. Scott, anyone?
Are they as good as described, or should i go for the original card instead?
