We believe in imagination, commitment, authentic passion for what we do. In the idea that, in an inflated world of objects, building a new product has no other meaning than to convey the energy of a creative act which, after all, says something about us, our history, our way of seeing things, therefore giving a meaning to what, in itself, has none.

Serblin & Son combines the legacy of the past with a modern approach to design assisted by the use of advanced electronic and mechanical simulation tools.

Frankie integrated amplifier streamer is the result of an experience that began well over 30 years ago …
A product entirely designed, engineered and developed in-house with proprietary circuitry.

It incorporates exclusive technical solutions such as analog volume control entrusted to a network of fixed resistors switched by relays with a scale of 127 steps, a solution that offers superior audio quality to both analog and digital potentiometers, guarantees perfect tracking between channels on throughout the whole attenuation scale and the consistency of performance over time.

Technical solutions of the best hi-end school combined with an elegant aesthetic appearance and ease of use within reach of a smartphone definately make the Frankie integrated amplifier streamer an exclusive product.

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.

Frankie monoblock balanced power amplifier employs the same original class A/B circuit topology of Frankie integrated where the two original stereo channels are used as the two halves of a monophonic balanced configuration.

The power transformer has been tailor made to meet the new condition in which the amplifier is called to work so it’s not just a Frankie integrated amplifier brutally bridged, which would ouput just too much voltage swing and limited current, but in fact a new tune in terms of voltage / current proportion in the output power.

While the Frankie power is than a natually balanced amplifier, we also provided an unbalanced RCA input to support a more flexible use of the amp.

In order to preserve the best sonic result even when feeded through the unbalanced input, we used a high performance texas instruments balanced driver supplied by a dedicated power supply rail of the trafo with discrete regulators.
This driver also works as a current buffer so we make sure the amp is driven the best way from a known low impedance source.

Short circuit protection and DC output protection are builted in the amp and controlled by a microprocessor.
Fault or overdriven condition are displayed through the 4 front leds.

PERFORMER integrated amplifier was born to bring the excellent sonic qualities of our FRANKIE to a smaller budget.
It inherits most of the original circuit solutions from FRANKIE, including the 127-level analog relay volume control, and employs a more traditional coated metal sheet chassis with a beautiful anodized aluminum front panel.

All functions are displayed on an OLED display.

PERFORMER integrated amplifier is available in two versions, with and without integrated streamer.
