Krell KRC-3 Preamplifier Line-Level XLR / Balanced / Made in USA Discrete / LOOK
You are bidding on a super high end Krell KRC-3 Preamplifier. This preamp sounds amazing and is in perfect working condition.

It's in nice condition and looks great but it has some light scuffs on the top and sides some of which have been touched up. You would have to be close and under direct light to notice it and is a non issue but is the only thing that keeps it from being mint.

Tektronix FM122 Low level preamplifier
This item is sold ASIS. It is in good condition. But we haven't tested if it's working. Also.The power cord is missing. Description: The Tektronix 122 is an external low-frequency low-level preamplifier. The low-frequency cutoff and high frequency cutoff can be selected. 40kHz is the highest cutoff. The input is differential. Using an XLR pro-audio style connector. The output is through a UHF(SO-239) connector, single-ended. The amplifier electronics are on a plastic board with metal studs where components are soldered in place. The board is mechanically isolated from the case by four rubber bushings. The 122 has four stages of amplification. The first stage is a direct-coupled differential amplifier formed by both halves if a dual-triode tube. The total plate current of the input stage is about 450uA. The second stage is a differential ... moreamplifier. Differentially driven by the first stage. There are DC blocking capacitors between plates of the first stage and the grids of the second stage. The second stage is coupled to the third stage by capacitors, which can be switched to select the low-frequency cutoff frequency. The third stage is a common-cathode amplifier formed from one half of a 12AU7 dual triode tube. The plate load resistors of the third stage amplifier are shunted by switchable capacitors, allowing the high-frequency cutoff to be selected. The resulting signal is buffered by a cathode-follower stage formed from the other triode in the third stage's 12AU7 tube, biased at 1.8mA plate current. The output impedance is rated to be about 1000 ohms. For low noise performance and freedom from oscillations. The power supplies in the 122 are carefully bypassed. The B+ supply of +135VDC(along with-90VDC and-6VDC) comes into the 122 through an octal connector, typically from a Type power supply. The raw voltage coming in is used for the plate supply of the output(fourth) stage. That voltage is low-pass filtered to produce voltage"C" which is used as the plate supply for the third stage.

CLASSÉ AUDIO MODEL 30 STEREO SOLID-STATE LINE-LEVEL & PHONO PREAMPLIFIER
Up for sale is CLASSÉ AUDIO MODEL 30 stereo solid-state live-level and phono preamplifier. An oldie but goodie that was an absolute rock in my previous analog system. It has given me flawless performance for eight years. And I expect it'll go on for much longer. The balanced output to the power amp and a balanced input are a big plus for this preamp. The preamp is configured for phono playback. The instructions in the manual show how to change the jumpers for moving-magnet or moving-coil cartridges. Very easily done. The only thing that needs to be attended to is a little noise on the volume pot that can be easily fixed with Deoxit or some other electronics lubricant. The preamp is in its original box with the metal remote. Manual, and IEC A/C power cord(see pics) It is being sold for $470 plus Fedex Ground shipping. Sold AS IS with ... moreno returns.
Upgraded Jolida JD5T Tube Line-Level Preamp Preamplifier
I'm selling a very good condition. Upgraded JD5T. The Jolida JD5T is an excellent entry level tube pre amp and an exceptional value. This unit is great for someone looking to get into the audiophile tube sound at a great price point. The stock 12AX7 Chinese tubes have been replaced with Tung Sol for refinement in the mid-tones. It has a solid, heavy feel to the casement. Also, this JD5T has been upgraded from the stock original 1.0uf output caps with 2.0uf Obligatto PIO caps, extending the bass, and giving a fuller midrange. Hard to beat at this price. No remote is included, but I'm told they are available from Jolida in Maryland as is the PDF Manual. The JD5T has 4 sets of RCA inputs and 2 sets of RCA outputs for bi-amping or 2.1 subwoofer. The JD5T is engineered as a simple tube pre-amplifier with two 12AX7 tubes in a buffered output ... morestage to add system warmth, functioning great as a preamp for a solid state amplifier. I'm sorry that the photo is not quality(I only have a camera phone) but I can attest that the item is in excellent condition. Of course, the other audiophile equipment in the photo is not included.

Preamplifier Stereo Line-level by Innersound with remote Solid State
$2.995 new, US sale only. Includes Home Theater Master SL-9000 remote that came with the Preamp. This is a strong little Preamplifier and well worth it for the money because of what it is. It doesn’t color the sound in our opinion. It has one small ding on the side of the front. Sonicly sound. The best for the money in this price range for Preamps. You can't buy anything that sounds or works better that is solid state in the $3.00 range new, so why not buy it lightly used for a 1/3 of the price. We can supply a copy of the manual for the programmable remote on paper or disc. We have pictures from almost every angle You could purchase a new combined Phono, stereo Line Level from Sanders Sound Systems for $4000 or so if you want to spend that much but if all you need is a simple pre without the Phono section this beats it all for the price ... morewe are asking. Innersound as a company no longer exists however Roger Sanders. Who made this preamp, of Sanders Sound Systems, got all the stock from Innersound when it went out of business.

The bass can be centered anywhere between 33 nad 500 Hz. The mid is adjustable ... morebetween 230 and-1.5 kHz and the treble ranges from 1.2k and 20k Hz.

The DA-P30 is the component depicted in the middle of the three components. The DA-A30 amplifier is the bottom component and is in my other auction.
