BAT VK-P10SE Tube Phono Preamplifier / Special Edition
The Path to the Ultimate in Analog Fidelity: Completely Revised First Gain Stage, Reconfigured Output Stage, Upgraded Power Supply, Flying RIAA Network
Ten-Tube Fully Balanced Design Offers Unfettered Dynamic Ease, Grand Sense of Scale, Unbelievable Drive and Transparency
The BAT VK-P10SE turns otherwise ordinary listening experiences into musical events. Made for listeners with the requisite turntable and cartridge combinations, this is a musical instrument of the highest class—a component that will honestly change the way you perceive what resides in your records’ grooves. Guaranteed. Its ten-tube, zero-feedback design and dual-mono construction help place the VK-P10SE on a pedestal approached by a select few high-end components and surpassed by none.
Serious Enhancements Result in Serious Sound A Special Edition version of BAT’s renowned VK-P10 phonostage, the VK-P10SE incorporates numerous engineering improvements to offer greater information retrieval and supreme musical presentation. The first gain stage is completely revised to provide a substantially lower noise floor. In addition, the reconfigured output stage incorporates four high-gain 6C45 tubes. They provide high-current and low-output impedance, establishing a superb level of drive and transparency. These enhancements result in a phonostage with improved silence in the quietest musical passages, unfettered dynamic ease, and grand sense of scale. Fully balanced, the VK-10SE achieves the best-possible performance when the phono cartridge is used in a matching balanced configuration.
Upgraded Power Supply, Extensive Flexibility, Dual SIX-PAKs The VK-P10SE boasts an all-tube zero-feedback design that combines the benefits of balanced operation with complementary vacuum-tube current sources. Dual-mono construction and enormous energy reserves are matched by extensive flexibility in cartridge loading. The first gain stage achieves a very low noise floor via premium Vishay Bulk FoilTM resistors that replace metal film resistors in critical areas. An upgraded power supply and dual SIX-PAKs of paper-in-oil output capacitors contribute more responsive, visceral bass. Vacuum-tube current sources further improve the linearity and yield a more open, textured sound. Here, dual 6SN7 vacuum tubes act as current sources for the second gain stage.
Flying RIAA Network Means You Hear LPs as Engineer Intended The VK-P10SE employs a differential RIAA network, permitting ease of adjustment and improved common mode noise rejection. Completely passive, this circuit has fewer components than a more traditional implementation. Such benefits translate into improved matching of the RIAA curve to specification. With the Flying RIAA network, you can be assured that all of your records sound the way that the recording engineer intended. And the VK-P10SE’s second-generation step-up transformers provide as much as a 20db improvement in signal-to-noise ratio in comparison to direct mode operation. With up to 80dB of gain available, there is no signal too small. Analog bliss awaits.

Parasound Halo A-51 Silver 5 channel Amplifier 400 x 5 A/ABMore Info
The A51 power amplifier combines raw power with elegant circuit design. Designed by legendary audio guru John Curl in collaboration with CTC Builders, the Halo brings uncompromising audiophile performance to home theater. Matched JFET inputs, MOSFET drivers, and high-current bipolar outputs contribute to its exceptional performance. Class A / AB Operation and Impressive Firepower The A51 boasts balanced inputs with discrete circuits and XLR connectors. Beautifully implemented high-bias Class A / AB operation makes the most of an impressive 250-watt-per-channel power output at 8 ohms and 400-watts-per-channel at 4 ohms. The 2.2 kVA encapsulated toroidal power transformer with independent secondary windings for each channel and 164,000 µF power supply filter capacitance delivers an impressive current capacity of 60 amps per channel. The direct-coupled design uses no capacitors or inductors in signal path. The complementary MOSFET driver stage relies on the firepower of 40 beta-matched 15 amp, 60 MHz bipolar output transistors and works in combination with a JFET input stage. The A51 has Parasound’s exclusive bias circuit, which permits the amplifier to sound perfect from the instant it’s turned on, rather than having to wait for bias to gradually build up as the amp warms up over time. Very high bias allows greater Class operating range than others. Even Halo’s implementation of its automatic turn-on feature is exceptional. Special relays bypass the AC “soft start” circuitry after it’s done its job for the purest AC and the purest sound. “Instant” Warm-up Feature. AC present, channel status, and high temperature indicators team up with DC Servo and relay protection circuits to keep this powerhouse running safely at peak performance for years of reliable service. Auto turn-on by 12-volt trigger or audio signal simplifies home theater and multi-room operation. Other features include heavy-duty 24k gold-plated 5-way speaker terminals, gold-plated RCA input jacks, and a rear-panel ground lift switch.
This A-51 has recently had it in-rush current limiter board updated and new caps performed at the factory under warranty.

Reduce unwanted high frequency noise (above 7 kHz) and low frequency rumble etc. (below 50 Hz) at 12 dB per octave rate.
FRONT PANEL TAPE JACKS
Allows connection to input and output of a tape recorder from the front panel. Inserting plugs into the front panel jacks disconnects the TAPE 2 circuits from the rear panel and uses the TAPE 2 facilities for the front panel jacks.
For listening with either low or high impedance dynamic stereo headphones. Power to this jack is supplied by an amplifier in the C 29. Headphone listening can be accomplished without the use of an external power amplifier.
(Operates with accessory speaker control relay) Turn Two sets of speakers on or off when properly interconnected with the accessory speaker control relay (the McIntosh SCR 2).
MAIN OUTPUT LEVEL CONTROLS
Permits the balance of the entire system to be conveniently preset.
HEADPHONE & LINE OUTPUT LEVEL CONTROLS
Adjusts the level and balance of the HEADPHONE/LINE output.
YOU CHOOSE FROM EIGHT DIFFERENT PROGRAM SOURCES
The input switch selects from six different sources or you can choose to listen to either of two tape recorders at the push of a button.
PRECISION STEP ATTENUATOR VOLUME CONTROL
Ideal volume control tracking accuracy and noise free performance are two of the considerable benefits of the McIntosh Precision Step Attenuator. It is a thirty-two step, 70 dB range control with unheard of tracking accuracy within 1 dB. The extreme accuracy is obtained through special electronically controlled resistance element trimming. The accuracy and quiet operation are maintained because the switch commutator touches only the switch contact pad and not the precision resistor elements.
AUTO TURN ON/TURN OFF
Power to the entire stereo system can be controlled from either the front panel power switch or the turntable’s power switch. A current sensing relay connected to the turntable AC power outlets is controlled by the turntable power switch. The relay, in turn, controls the AC power to the remainder of the system.
STEPPED TONE CONTROLS INDEPENDENT IN EACH CHANNEL
Settings are precise and repeatable in each channel, independently. Each tone control is a separate eleven position switch concentrically mounted. Each step is connected to carefully selected resistors and capacitors to give the precise frequency curve shape. Because the tone circuit component parts are not in contact with the switch surfaces, as in ordinary continuously variable rotary controls, they never change, never get noisy and provide exact, repeatability settings.
YOU ALWAYS GET THE IDEAL STEREO IMAGE
The McIntosh seven position mode selector has facilities to permit the correct balancing of a stereo system to maximize stereo imaging.
YOU CAN LISTEN AT LOW VOLUMES WITH EQUAL PLEASURE
A continuously variable loudness control lets you enjoy full frequency response and warmth of music regardless of the room volume you choose. As volume is reduced, the frequency response is adjusted to complement the human ear response characteristics, the Fletcher Munson effect.
TAPE RECORDING AND PLAYBACK MADE EASY
Tape input, tape output and switching facilities are provided for two three-head tape recorders. Simply push a button to listen to either one, or – record from any selected source on either or both, or- copy from one tape recorder to another while listening to an entirely different program. You can instantaneously monitor either tape recorder.
STEREO MICROPHONE INPUT MAKES RECORDING EASY
Microphones in stereo may be used with the C 29. By tuning the input selector to MIC the microphone set-up will be connected to either one or both of the two tape recorders connected to your system.
THE CONSTANT LOUDNESS BALANCE CONTROL
The McIntosh balance control adjusts each channel independently for stereo imaging without changing overall stereo volume in the room. While natural balance is at the center of the control; adjustment to either right or left compensates for program variations or room acoustic differences.
LISTEN TO YOUR QUIET RECORDS, QUIETLY
Any unwanted noise (hiss, rumble, fry, etc.) can be reduced with the filter switch. It allows the reduction of low frequency noise and high frequency noises (below 50 Hz and above 7 kHz).
CONTROL REMOTE LOUDSPEAKERS FROM YOUR PREAMPLIFIER
Through a unique McIntosh design, you have ON/OFF control of two separate sets of stereo speakers when used with an accessory switching relay (the McIntosh SCR 2).
