Designed by the leading engineer of the American firm Manley Labs, Mitch Margolis, Snapper monoblocks are characterized by fully balanced circuitry, including input and output stages. The balanced circuit makes the amplifier insensitive to fluctuations in the anode supply. The enormous energy (180 J) stored in capacitors and power filters significantly reduces the impact of the load on the output stage. The latter is made on EL-34 lamps in the ultra-linear mode, which is also less dependent on load fluctuations than the pure pentode mode.
The value of the balanced circuit also lies in the fact that unbalanced RCA inputs can be used with equally impressive results. The displacement of the lamps of the output stage is regulated by resistors located, like the control sockets, on the upper panel. Acoustic connectors of the German company WBT.
The transformer of the new design is a complex device, the windings of which consist of 19 sections. The Snapper is capable of delivering 100W of power at 10Hz for an unlimited time, and in the 15kHz – 40kHz frequency range, the full power output rises to 110W. It has excellent pulse and phase-frequency characteristics.
Broadband transformerless balanced-bridge circuit with input impedance switching and input sensitivity change (the latter is implemented by selecting the appropriate resistor). An unbalanced mode of operation from a balanced input is possible, for which the 2nd or 3rd pin of the balanced input connector is grounded.
Incandescent input and output lamps powered by direct current.
