Price is for a pair! The Snappers have been a long time staple in our high end TTVJ system. We love them! Punchy, lively, and overall wonderful sound emanates from the Snappers. The sound is so seductive and involving it just draws you in and gives you no choice but listen and enjoy! Highly recommended and a component we personally use!
In 2002 we launched a very tasty all-tube 100 watt monoblock called The Snapper® (oceanic names continuing). At $7,600 per pair for stereo playback, we also welcome you to catch a school of Snappers for surround systems.
Another brilliant design from Mitch Margolis features a quartet of EL34 or 6CA7's in a fully differential circuit topology, including the input and driver stages. This Snapper can be driven fully balanced all the way through via the XLR inputs. If you have balanced outputs on your preamplifier, this amplifier is the first Manley design to really let you take advantage of your XLR's without additional balancing input circuitry or input transformers. Very cleverly, the unbalanced RCA's can alternatively be used in this special topology with equally impressive results.
Biasing is easy with all measurement points and trimpots located on the top deck and speaker connection is made with heavy duty WBT binding posts.
Over three months of prototyping in the Manley Magnetics department resulted in a brand new output transformer design, a true 19-section incredibly complicated piece. The Snapper will crank out 100 watts at 10 cycles all day long and a full 110 watts from about 15Hz all the way up to 40KHz. Don't let frequency response specs fool you when people give you amazing bandwidth measured at... oh, five puny watts. We're talking full power bandwidth here! Continuous duty. Real muscle.

Features and Specifications
- 100 Watt partial triode (UltraLinear) EL-34 output stage is tolerant of a wider variety of output load conditions than pure pentode.
- Precise and balanced signal path from input to output. Circuit self-balances with either single-ended or balanced inputs. [Don't let either speaker terminal contact chassis, earth or any other ground.
- Switch-selectable RCA unbalanced inputs, or XLR balanced inputs. RCA jack input impedance about 330 kOhms, XLR 15 kOhms. If one input is not occupied, the input selector switch may then be used as a poor-man's MUTE switch. Handy for checking the bias, swapping input cables, etc..
- Input Sensitivity RCA jack: 750 mV RMS for full output into 5 Ohms
- Input Sensitivity RCA jack: 71 mV RMS for 1 watt output into 8 Ohms
- Input Sensitivity XLR jack: 1.5 V RMS for full output into 5 Ohms
- Overall voltage gain RCA jack to Output: 31 dBu, or about 32 volts per volt.
- Signal to A-weighted noise ratio on Humberto's bench is about 110 dB.
- Damping Factor: 4.7
- All-balanced amp topology keeps B+ voltage variations from degrading the performance of the input and driver stages. This technique can help make a push-pull amplifier very revealing of signal detail, in part by canceling power-supply-related perturbations and increasing signal-to-noise ratios.
- Portly 180 Joule energy storage reservoir in the main B+ supply channel for explosive transient response and athletic musical stamina. Also reduces B+ fluctuations due to varying current demands of output stage.
- Wideband transformerless balanced input with bridged 15 kOhm input impedance. Balanced input sensitivity may be selected by changing one resistor to suit whatever operating level may be required. 0 dBu, +4, +8, etc... If desired, the user may safely ground either pin 2 or 3 for single-ended drive of the balanced XLR input... [Be careful NOT to drive pins 2 and 3 of the XLR with a large common-mode signal, or the internal B+ fuse could blow.]
- Quiet DC supply for the input and driver tube filaments.
- Excellent square-wave response, and very low excess phase-shift with frequency.
- Amp actually puts out 110W @ 5 Ohm load @ 2 kHz @ onset of clipping, 117 VAC mains voltage, 3.5 amps mains current.
- 100 W spec: 15 Hz - 40 kHz into 5 Ohms
- Puts out 100W into an 8 Ohm load.
- Snapper unit weight: 38 lbs.
Rear View Detail
Snapper gutz. Undercarriage view. Naked. You can see the big chassis strengthening strut inside so the heavy transformers won't cave the chassis in if UPS throws it off an airplane...
NOTE: As of early 2008, the B+ fuse value has been changed FROM 0.4A (4/10th Amp or 400mA) TO 0.5A (1/2 Amp or 500mA).
Same type and location inside the amplifier. MDA 1/2A Ceramic SLO-BLO 1/4" x 1 1/4"
Applies to all Snappers.
Users with existing Snappers fitted with 4/10th Amp B+ fuses can uprate their fuses to the new higher amperage part should their 4/10th amp fuse blow. No need to change to 1/2A part until/if existing 4/10th Amp fuse blows.

The test report puts the SNAPPERS second to none in their category. Roland Kraft: "They are without any doubt the quickest, liveliest and most thrilling high performance tube amps I have ever encountered. They may not be quite as colorful as triodes, however offer a bass foundation that triodes are never able to deliver."
