B.K.Butler REAL TUBE II Tube Works RT-922 Tube Preamp and Mos Valve MV-926 Combo Rack Mount Amp/Pre-Amp With Road Case.

You are bidding on a fully functional amp/pre-amp combo. They do not make Real Tube amps anymore and they are awesome! All the necessary cables are included except the ones that will run to your speakers. I am selling it because I am moving out of the country and cannot afford to take it with me. User manuals can be found here: http://www.genzbenz.com/?fa=manuals

Shipping is expensive because the thing weighs 30lbs. Includes shipping Insurance. Will be packed with care (packing peanuts and everything) so no need to worry. Payment Is required within 24 hours or you will be reported to ebay and a dispute will be opened with pay pal. Sorry for the strict restrictions but I am moving in 3 weeks and pay pal usually holds the payment for 14days or until the buyer leaves feedback. So please help me out and leave me feedback as soon as you receive it and test it!

*Sorry I will only ship to the 48 States, HI and AK jsut cost too much.

*By bidding you are agreeing to all the terms I have layed out above.

p.s. there is a piece of electrical tape on one of the cables in one of the pictures, I have no Idea why it was there when I took the picture, don't worry the cable is fine.

MosValve 962

MosValve 962 Operation Notes • This amplifier was designed primarily for musical instrument amplification. It is an addition to your audio rig which will add warmth and definition to your sound. • Use MosValve with any preamp capable of producing 450 MV into a 50K load (Virtually any preamp in existence.) • Use with speakers or cabinets capable of at least 80 watts RMS continuous power. Re- member that MosValve can typically produce in excess of 100 Watts/channel under typical conditions common on stage today. At least 100 Watt speakers or cabinets are therefore highly recommended if you intend to use the amp at high power output. MANUFACTURER IS NOT RESPONSEBLE FOR ANY SPEAKER FAILURE WHILE USING THIS EQUIP- MENT. • This is a stereo power amp. Mono operation is switchable (both channels. input bridged) with the use of single input plugged into Channel A. Stereo operation is automatic when an additional input is plugged into Channel B. • It is often advisable to use only one channel for mono (for example, if you have only one speaker cabinet), as the MosValve can produce over 100 Watts with only one channel driven. Use Channel A and set Channel B controls to "O." NOTE: It will not damage Chan- nel B to have no speaker plugged into it while using only Channel A. • NEVER attempt to power bridge the two speaker output channels together. NEVER parallel or series them into one speaker or cabinet. If power from both channels is used, ALWAYS use at least two separate speakers (one per channel) or separate speaker cabinets per channel. ALL WARRANTIES WILL IMMEDIATELY BECOME VOID IF ANY ATTEMPT AT POWER BRIDGING, OR PARALLEL / SERIESING OUTPUTS ARE MADE!! • A certain amount of heat during operation is normal. The MosValve amplifier is biased in a manner in which even when idling there is some heat present. It is best to keep the ampli- fier towards the bottom of the rack (coolest air) and avoid obstructions to the vents in the case. • Never load the speaker outputs with less than 4 ohm loads. These can be single speaker cabinets per output or a combination of two cabinets per output. Examples of cabinet com- binations: Per Channel: One 4 Ohm (or higher) or Two 8 Ohm (or higher) TECHNICAL SPECS OUTPUT POWER — 160 Watts RMS at 4 Ohms (80 watts per channel, both channels driven) S/N RATIO — Better than 95 dB at 8 Ohms HUM & NOISE — Better than -65 dBv at 8 Ohms (No input with controls at maximum) SENSITIVITY — (For Rated Output): 450 MV (-5 dBv) INPUT IMPEDANCE — 50 K Ohms PRESENCE CONTROL — +/- 8 dB at IO KHZ (I 6 dB range) MAX POWER CONSUMPTION — 120 VAC, 400 Watts (220-240 VAC, 50/60 HZ: 200 Watts) COOLING SYSTEM — Constant-turbulence internal fan SHORT-CIRCUIT PROTECTION — Inherent to the design, thermal runaway-proof SIZE — 3 1/2" H x 19" W x 7" D (Standard 2-space rackmount format) (D = behind front panel) OVERALL DEPTH — 8 1/2" WEIGHT — 13 Lbs. Real Tube™ II Rack We thank you for your purchase of the most versatile and best designed tube preamp rack on the market. We are confident this product will meet your desires to acquire the Real "TUBE" sound. TAKE TIME TO KNOW THE "RACK" The rack is a very versatile unit. Please take the necessary time to look over this man- ual and become familiar with the basic layout of controls as well as the unique fea- tures. Take time and let your ears guide you through the tonal possibilities. The EZ sections have been carefully optimized for current and classic playing styles and have an extremely wide range of control. It is possible that you may be just a "tweak" away from your desired sound, so be patient and jot down the settings that you prefer most. Also become fully aware of the several mode combinations possible with the two chan- nels plus the channel stacking feature. APPLICATIONS OVERVIEW The Real Tube II Rack is a two-channel tube preamp designed for guitar use. The wide input range of channel 2 allows it to remain clean even with high transient inputs. The stereo effects loop and adjust- able send and receive levels aid greatly in achieving proper signal level and signal to noise ratio regardless of the effect used. This unit can be used with either basic power amplifiers or combo (Instrument level) amplifiers. We strongly recommend that you audition this preamp with our MosValve power amplifier, as this combination will insure optimum tone and performance.

FRONT PANEL CONTROLS (Left to Right) CHANNEL SWITCH — Switches between channel 1 and 2. This switch is overridden when a footswitch line is connected to the channel jack on the rear panel. STACK SWITCH — Switches the unit in and out of the “Stack” mode. BOTH Green and Red LEDs light in this mode. The stack mode (Stack switch up) is when Channel 1 is driven into Channel 2. With the stack mode selected, the “Channel” switch alternately selects Channel 2 (clean) and Stacked - Channel 1 into Channel 2. NOTE: All controls function in the Stack mode EXCEPT “Volume”. “Stack Master” is active only when the single Green LED is lit. This switch is also overridden when a footswitch line is connected to the “Stack” jack on the rear panel. INPUT JACK — Standard guitar input. Wide-range for both Active pickups and Bass and Key- boards. CHANNEL 1 CONTROLS DRIVE CONTROL — Sets the amount of signal gain at the first stage of the tube for Channel 1. Increasing the setting of this control results in more sensitivity and sustain. This, as well as the next control listed will have a great affect on the quality of the actual overdrive texture ob- tained as BOTH "Drive” and “Contour” are PRE TUBE controls. CONTOUR CONTROL — Adjusts the amount of low frequencies or "bottom end” driven into the tube. Some players prefer a fatter, “Boogie" or "Fender" texture to their overdrive, while oth- ers prefer the more high-ended “Marshall” type edge. Moving the control toward “10” gives a fatter sound, while toward “0” will give a thinner, more biting tone. It is usually advisable to use thinner (lower numerical settings) for playing chords in overdrive, while single string leads may sound better with higher settings. (More bottom-end). MASTER CONTROL — Sets the over-all output level of Channel 1. In the "Stack” mode, this control becomes a “Drive” control for the second tube Channel as well. HI CONTROL — Adjusts high-end. Set at 1500 Hz and higher. MID CONTROL — Midrange frequencies. Center is 500-800 Hz. LOW CONTROL — Shelves off lower frequencies from 100 Hz down. CHANNEL 2 CONTROLS VOLUME — Signal gain level. This control functions only with the single Green LED lit. As channel 2 is primarily a clean channel, there is no dedicated master volume control; it is like an old 4-input “Marshall”. STACK MASTER — This control is operational only in the "Stack'“ mode. It is functional only when BOTH LEDs are lit. This is the overall Master Volume control in the "Stack" mode. HI CONTROL — Adjusts high-end. Set at 1500 Hz and higher. LOW CONTROL — Shelves off lower frequencies from 100 Hz down. NOTE: In the “Stack” mode, BOTH EQ sections are active. Channel 1's EQ is between the tube output in Channel 1 and before the tube in Channel 2. Channel 2's EQ section therefore becomes the overall output EQ controls. POWER SWITCH — Supplies main AC power to the unit. Either LED or both light (depending on mode selected) when power is "on." REAR PANEL LAYOUT (Left to Right) LINE CORD — Be sure to connect the unit to the proper voltage source. The current draw is negligible, a maximum of only 10 watts is consumed, but the unit can be damaged if proper voltage ratings are not adhered to. LINE OUT JACK (Ch A) — Line level output jack. This level will drive basic power amps, and operate at nominal line levels (0 dBm). Use Channel A for MONO operation, however an iden- tical signal is available at Channel B line output in MONO operation. INST. OUT JACK (Ch A) — Instrument (guitar) level output level jack. This output should be used to connect the unit to the input of a regular combo or stage amplifier instrument input. LINE OUT JACK (Ch B) — Line level output jack. This level will drive basic power amps, and operate at nominal line levels (0 dBm). INST. OUT JACK (Ch B) — Instrument (guitar) level output level jack. This output should be used to connect the unit to the input of a regular combo or stage amplifier instrument input. EFFECTS SEND LEVEL — Adjusts level output for effects send. EFFECTS SEND JACK — Effects send (OUT). EFFECTS RECEIVE LEVEL (Ch A) — Adjusts receive sensitivity for Channel A effects. EFFECTS RECEIVE JACK (Ch A) — Effects receive jack for Channel A. NOTE: Use only this jack for receiving MONO effects. The signal will automatically be fed into Channel B receive. Both receive level controls can be adjusted (Use both A and B input jacks for receiving true stereo or “panning” effects). EFFECTS RECEIVE JACK (Ch B) — Effects receive jack for Ch B. NOTE: True Stereo opera- tion is obtained when using a stereo or “panning” effects device plugged into both A & B Ef- fects Receive Jacks. Stereo outputs A & B (both line and instrument level) can then be routed to either a stereo power amp, or two separate combo amps, etc. DRY OUT JACKS — Both Line and Instrument level output jacks for dry (before and inde- pendent of effects section) signal. These outputs can be used for monitoring and/or additional effects, remote patching applications, etc. FT. SW. STACK & CHANNEL JACKS — Permits the use of standard “on-off” footswitches to remotely switch the “Stack” and “Channel” functions. (Front panel “Stack” and “Channel” switches are automatically overridden with footswitch use.) NOTE: These jacks are Positive signal-to-ground switching logic and should operate with MIDI switchers, which use positive open collector switching schemes.
