Protect your investment with aPlatinum Coverage warranty plan:
There are no products for the condition you selected. Please make another selection.
This instrument or product has been carefully played/used and returned to us in
virtually new condition, however its packaging may not meet the standards set by
the factory. Also, it no longer carries the manufacturer's warranty. If you're looking
for a virtually new instrument in possibly less-than-perfect packaging, this is
a great value. We feel so strongly you'll like what you see, we're including our
60-Day Satisfaction Guarantee on instruments and 30 days on accessories, to this used product making it a no-risk purchase.
Very Good: This instrument or product has been carefully played/used and shows few,
minor signs of use. In most respects it looks and performs like new and may be considered
equivalent to display units found in retail stores. Its packaging may not meet the
standards set by the factory and it no longer carries the manufacturer's warranty.
Condition 2 products are a terrific value and you can buy with confidence knowing
our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories applies to this used product.
This instrument or product is in good working condition but has one or more cosmetic
flaws beyond those of a Condition 2 product. These flaws are typical of an instrument
or product that's seen normal wear and tear, including incidental scratches, chips,
dings, dents or other imperfections. It performs just as well as a Condition 1 or
Condition 2 instrument/product. Its packaging may not meet the standards set by
the factory and it no longer carries the manufacturer's warranty. Condition 3 is
a great choice if you're looking for performance and value and not as concerned
with cosmetics. You can buy with confidence knowing our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories
applies to this used product.
This instrument or product is not in working condition and needs repair, but can
be brought back to full functionality with replacement of parts or some skilled
repair work. If you are a do-it-yourselfer or know a skilled repair person this
is a terrific value. Condition 4 products are sold AS-IS: they do not come with
a manufacturer's warranty and are not returnable.
This instrument or product has been damaged beyond what we judge is reasonably repairable.
It's best used for spare parts or to practice repairs on, and at this price Condition
5 products are sold AS-IS: they do not come with a manufacturer's warranty and are
Accidental damage, normal wear and power surges are no longer an issue with these comprehensive and affordable plans. We even pay to ship your gear for repairs. More details.
Covers much more than the original manufacturer's warranty:
Limit of Liability: The least of the cost of (1) authorized repairs, (2) replacement with a product of similar features, (3) reimbursement for authorized repairs or replacement or (4) the price that you paid for the product.

Tube-Tech SSA-2B Stereo Summing AmplifierYes, you can mix inside the box and get good results, but with the Tube-Tech SSA 2B Stereo Summing Amplifier, you can mix inside a much better box and get stunning results. Where extremely high-quality summing of several signals into two channels is desired (and where isn't it?), the SSA 2B is a top choice. Tube-Tech SSA 2B Stereo Summing Amplifier, First Take:Ultra high-quality summing amplifier with very wide frequency response8 stereo/4mono inputs summed to 2 channels out Inputs balanced by zero field transformerBalanced and fully floating outputsUltra High-Quality Summing AmplifierThe rackmountable Tube-Tech SSA 2B Stereo summing amplifier features two very low-noise, low-distortion summing amplifiers with a very wide frequency response of 5Hz — 100 kHz. The inputs are transformer balanced and the circuits are symmetrical from input to output. The inputs are also capable of handling extremely high input levels. 8 Stereo/4 Mono Inputs Summed to 2 OutputsThe Tube-Tech SSA 2B summing amplifier has 4 mono input (hard wired to CH1 and CH2) and 8 stereo inputs, which are summed to two outputs. The SSA 2A consists of a summing amplifier at the input, a 23 stepped attenuator with a range of +/- 10 dB and an output stage. Two large VU-meters show the levels on the XLR output sockets. To avoid the distortion introduced by the VU-meters when connected directly to the output XLR sockets, symmetrical configured OP- amps buffer the VU-meters. The summing amplifier is a symmetrical two-stage amplifier, designed around two dual, low impedance, and high transconductance triodes. The input transformer is part of the dual feedback configured as a so-called zero field transformer. The attenuator is a heavy gilded 2 x 23-position switch with steps of +/- 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10dB. The output stage is designed around two dual triodes in push-pull and an output transformer (with a static screen). Both the summing amplifiers and the output amplifiers are symmetrical. Zero Field Transformer-Balanced InputsAll inputs on the Tube-Tech summing amplifier are balanced by two zero field transformers (one for each channel). In zero field transformer configurations, the transformer is part of the feedback circuit. There are several benefits to be derived from this: 1. The voltage across the transformer is reduced substantially, whereby a much smaller transformer is needed for the same specification. The reduction is of the same magnitude as the feedback applied. 2. The distortion at low frequencies is reduced substantially. 3. Frequency response in both the low and high range is extended. 4. Phase response in both the low and high range is more linear. The results are better harmonic balance of the instruments and more realistic sound.Balanced and Fully Floating OutputsThe outputs are balanced and have fully floating transformers with a static screen. Floating a transformer (not referenced to ground) provides maximum electronic isolation for superior noise rejection. The static screens shield the transformer's secondary windings from the primary and prevent RF (radio frequency) electromagnetic noise from getting across. The Tube-Tech amp's Line Input is unbalanced, but an optional transformer is available, which will allow the line in to act as though it's balanced. The power supply and the sidechain circuits of the Tube-Tech SSA-2B summing amplifier are based on a solid-state circuit. With the exception of the output stage all DC voltages are stabilized. This prevents any variation in the DC energy when combined with the musical signal, which would otherwise cause certain types of distortion or hum.About Tube-TechFor over twenty years, Tube Tech has been one of the most prominent names in all-tube signal processing equipment. You'll find their gear in the best recording and mastering studios around the world. The company's founder, John Petersen is an electrical engineer who was factory trained at Solid State Logic, EMT, Studer, Sony, Neumann, and NTP Electonik (digital audio routers). He also designed tape recorder playback/recording amps for Lyrec tape recorders (found in the studios of the legendary Joe Meek and Vangelis). His first design under the name of Tube-Tech was an all-tube equalizer based on the legendary Pultec EQP 1A. Petersen continued to design and manufacture a number of innovative all-tube outboard processors including preamps, multiband compressors and summing amps. Thanks to John's dedication to high-quality analog sound you'll see Tube-Tech amplifiers and gear in the audio racks of pro audio legends such as multi Grammy Award winner Al Schmitt, (Frank Sinatra, Steely Dan, Toto, Quincy Jones, Natalie Cole, Diana Krall), Grammy winner Joe Chiccarelli, (Elton John, Beck, U2, Tori Amos, Counting Crows, Offspring), engineer Russ Long (Sixpence None The Richer, Wilco, Dolly Parton, Allison Moorer), producer-engineer Tony Shepperd (Elton John, Madonna, Kenny Loggins, Barbra Streisand, Lionel Richie, and Whitney Houston), and many more.
