Phono 70

                                                 Introducing the Paradox Phono 70

The 70 (70db of voltage gain) is a low output Moving Coil (MC) phono amplifier.
There are no switches in the signal path (switches degrade sound period) so there are no provisions for less gain.
If you want less gain purchase the Phono 40 (has RIAA and 47k input impedance) or Phono 30.

Highlights that actually mean something;
70db of overall voltage gain, will work with 0.1mv cartridge.
Passive RIAA, using Audionote tantalum resistor and matched precision parts for highly accurate full range equalization.
PI filtered power supply with Mundorf Mlytic, styrene bypasses and isolation.
Simple ultra low noise JFET circuit using the LSK170.
PIO coupling capacitors.
Cardas phono wire for signal path.
Special circuit board using RIVER technology, must be engineered for each product, is not a program.
Input impedance 100k ohms with infinite loading possibilities via external RCA mounts.
Damped rigid chassis and high quality connections.

Completely hand built and assembled.
Two year warranty bumper to bumper.

LOADING read thoroughly with intent to understand;
Input impedance 100k ohms on board permanent load, your external load is in parallel and necessary for the MC cartridge to sound proper.
NO damage can occur if an external load is not present but the sound will not be good.
The use of external load is in parallel to the 100k making your actual value slightly less than actual load resistor value.
Load resistors are a component that goes from the input signal to ground/"0".
There is no advantage whatsoever in using anything but precision metal film as it will NOT matter sonically since it goes to ground!

Load resistor mounting;
A pair of 400-ohm resistor has already been inserted into the screw down RCA as an example.
I like to bend the ends of the load resistor over a 1/4" and then insert into the end of the RCA with the screw terminals.
Loosen RCA screw end in preparation for the load resistor. Insert ends of resistor and tighten screws down.
Build as many values as you like but you will have to label them.
It is easy to get them mixed up if YOU don't use caution and keep pairs together a rubber band or tape will keep the pairs together.
You can also build your own male RCA's with a resistor soldered in place but the sound will not improve so why waste the money.

Specification which have no sonic merit;
SNR: >80db
ID: 0.001
THD: <0.01%
