Urei  1620  rotarymixer  enhancement

     An original Chicago Warehouse DJ Jeff Sims recently came to me with his original UREI 1620 Rotary Mixer.  His main issue what was the the phono pres on this mixer are so high gain and sound so awesome that the passive RCA inputs sound weak when using more modern DJ equipment through those inputs.

    I fixed this first by designing my YO'UREI AUX BOOSTER CARD.

    I then modded the two phono preamp cards which Jeff told me sound better than a Bozak mixer he had just gotten.

    I recapped the whole rest of the unit.

    The end result is the best sounding DJ mixer on this planet.

    There are a lot of people who blindly use "whatever" capacitors they happen to see on a forum somewhere. I however have over a decade of electronic component sonic quality know-how.  I KNOW what capacitors sound good.  Not all forum proclaimed boutique capacitors sound good in every single application.

As of  Nov 2017:  I am also upgrading a few really important signal path resistors. I use a combination of awesome sounding carbon comp and vishay 1/2 metal film resistors. They are the CLEANEST sounding resistors around. Also!!! I've started to replace a commonly over-looked tone sucking resistor network. I replace this and install metal film instead. This is a crucial set of resistors.

As of Feb 2018:   I've expanded my use of different op amps. 

Any other requests to upgrade other components will be subject to extra charges.

To book your modification which automatically comes with the booster cards contact me.

Cost of the upgrade minus the Booster Cards is $500.  (This includes upgrading 2 phono pre cards).  Pricing for the booster cards can be found on the YO'UREI AUX BOOSTER CARD page.   If you include 2 or 3 booster cards with your mod, I'll give you a $50 dollar discount off the total mod price.
