Paradox Phono 70

I would like to introduce the "Paradox Phono 70"
This is 70 db of passive RIAA gain which will be enough for most any MC cartridge you want to use and it will certainly work for the Paradox Pulse R SMR at about 0.3mv.

Key features
-External power supply with voltage display, set at 18v can vary 17.5 to 18.5 volts
-external loading via RCA's and reusable screw down RCA's
-JFET low noise amplification
-Passive RIAA with only 1 tantalum resistor in the signal path along with 3 JFET's and 3 coupling capacitors
-70 decibels total of low noise gain
-All components are matched from the LSK170 JFET's through RIAA critical components
-Special Litz wire used for all signal and power supply paths
-Ultra high quality parts used throughout like Mundorf 10kuf M-Lytic one per channel
-No crappy switches to degrade the signal path
-Comes with many pairs of load resistors, additional loads upon request.

Like my other Pulse products the Phono 70 has a money back guarantee less any shipping (both to and from)  along with potential refurbishing costs for those that like to "kick" it around! If it returns in the same condition I sent it to you, all monies are refunded less shipping.  $2500- simply amazing.

See 70 owners manual page for more information.

Phono 70

This is how the standard Phono 70 is packaged.


When the 70 arrives it will be very well protected.
It comes well packed in a plastic case using pluck foam to safely hold and protect its content.
You will notice the white plastic wraps the 70 itself. Load resistors and their RCA's set on top. The power supply above. AC power cord to the left and the DC umbilacle to the right.
This is the base Phono 70 kit. Upgrades are available see store or give me a call to find out more.

How to load your Phono 70

See below for how to build extra loads from parts included in kit.

Kit has one assembled load set of 402 ohms.

The picture to the right is all the additional parts that come with a Phono 70 kit besides the power supply and 70 itself.
The power cable connects to the power supply and your AC outlet. 
The power supply display will read approximatly 18 volts, any voltage between 17.5 and 18.5 volts is proper. The power supply itself is set to 18v but your wall voltage vs. my voltage can make a difference of a couple of 10th's of a volt, do not be concerned. There is an adjustable pot inside that can be used to get 18v exactly but it is not important to the sound performance of the 70 so relax and enjoy on what ever the display reads.
Connect the umbilicale between the power supply and Phono 70 using the port on the back of each marked power.
Keep power supply far away from Phono 70 to avoid hum noise. If you have any hum noise check location of 70 with respects to other equipment with power supplies located to close.

Load resistor build
You will have extra RCA's with screw terminals. Grab a pair of values you would like to try and empty RCA's. Now you are ready to build.
Bend leads
It is as simple as the picture implies, bend the ends back on themselves (this gives more bite for the screw contact but is not necessary) then fold over. Loosen both set screws on the end and insert.
Phono 70 wiring kit with loading resistors. How to make more loads!
Each 70 comes with everything you need to get the most from your moving coil cartridge.
One pair of loading resistors is already assembled for you as a reference for you to copy when you build other values included in the kit.
Loading resistors go to ground and there is absolutely no sound improvement from using expensive resistors, precision metal film is all you need. We include 1% metal film resistors so each load value is precise.
Insert resistor
Now that the resistor is inside the screw terminal end tighten screws.
This will hold the values firmly in place.
Now insert RCA into the back panel of the 70 marked LOAD. This can be done on the fly while system is playing records.
