Frankie hybrid preamplifier

The beating heart of Frankie hybrid preamplifier, the line amplifier, consists of a 4x 6DJ8 double triode configured as a SRPP balanced circuitry with an active cascoded mosfet current sink.
The circuit, with zero averall feedback, benefits of 4 separate and regulated power supplies with discrete components.

The volume control is once again our “golden stairway”, the attenuator developed in house and used in all our products.
This attenuator, made up of fixed resistors switched by relays, has a precision and quality superior to common analogue or digital potentiometers.

Phono input is a solid state circuit suitable for both MM and MC cartridges, it benefits from an ultra-low noise discrete FET input, a fully passive RIAA network and a balanced output.

The dip switches on the rear panel offer a wide range of capacitance and resistance adjustments for the cartridge interface.
Obviously the phono board has its own dedicated power supply.

The preamplifier can be controlled both via iOS & Android App or via infrared remote control at the same time.

Frankie hybrid preamplifier has been designed to be the ideal partner of the Frankie monoblock power amplifier.

Frankie hybrid preamplifier is available with an on-board MM/MC phono card or with an additional RCA input card as shown in the images.
The choice of one or the other solution while purchasing the unit can be easily reversed in a later time
