YAQIN Vacuum Tube Pre-Main Amplifier MC-100B KT88 Push-Pu Vacuum Tube Pre-Main Amplifier MC-100B ( KT88 push-pull ) This product has been tested for sound output.(Sound is normal from bass to treble.) All inputs and selector positions are normal, and there is no buzzing in the volume. Each vacuum tube lights are also normal.(Please check with the pictures.) Please refrain from turning the power on and off continuously, as this will cause a pop noise. (It may be improved by replacing parts, but we do not know because we have no knowledge about it.) Unlike a transistor amp, this is a vacuum tube amp, so there may be a slight chirping sound when silent. About sound qualityUnlike its flashy appearance, the sound quality is good, and the rough sounding speakers become calm and thick. The sound quality is good, unlike the flashy appearance, and the rough sounding speakers become calm and thicker.In addition, since it is a KT88 push-pull, it has a lot of output power, and I think it will be loud enough except for speakers with a very low performance ratio. I dont think you will be bothered by the lack of output power that is common in vacuum tube amps. Therefore, I personally recommend push-pull amps with more power than single amps.(?All of the above is my personal feeling.)

I have owned this amp for almost two years but not currently using it in my set up, I have two other valve amps. This is the most powerful at 60RMS per channel. Even the 25RMS per channel valve amps are ample power for majority of tower speakers. Amp is in good condition, 240v power supply.

Beautiful tube amplifier. Rarely used and carefully handled. In near mint condition. Ships with all original accessories and documentation in the factory shipping box. This is a chance to own a really wonderful sounding amp in great condition from a single, careful owner. Happy buying!

***PLEASE READ THE FULL DESCRIPTION BEFORE BIDDING AND MAKE SURE YOU ARE OKAY WITH MY NO RETURN POLICY*** Works perfectly! Tested thoroughly prior to listing. I am selling this AS-IS, FOR PARTS/NOT WORKING, because I DO NOT ACCEPT returns on electronic items. Please see photos for detailed condition. Because of this, I am starting this listing at $1 with NO RESERVE. This is the most incredible amp I have ever owned, and it breaks my heart to let it go! Comes in ORIGINAL Factory box, with BRAND NEW factory (China) tubes, all instructions and tools. The sound is INCREDIBLE! Holographic and expansive. Clean and clear and warm. Pushed my power-hungry speakers with EASE. You MUST adjust the bias on this amp ANY TIME you change the tubes. Failure to do so can damage the tubes. Instructions and tools for doing this are included in the manual/box (see photos). You will also need a cheap multimeter. This amp is very sensitive to voltage. I ran it on a VARIAC turned to right around 100V, and it never had a single problem or blown fuse. I strongly recommend you pick up a decent variac and give it less than 120V +/- for longer life and better sound. In addition to the stock tubes (which I put back into the amp for shipping), I found the best combo (to my ears) of rare and vintage tubes. Included in the auction are (all pictured): 4 Shuguang Treasure KT88-Z $129/pair2 Brimar 6SN7GTY KB/FE (CV1988) (13D2) (B65) Black Beauty Rare $5-600/pair2 RCA 6SN7GT Gray Glass Tube $2-300/pair2 Shuguang Golden Dragon 12AX7 Tube $200/pair The rare tubes will ship in a separate box in their original packaging and carefully padded and insured. Also included is a small DSD sabre DAC (https://www.spaceaudio.eu/old/) that can stream via USB, and some ultra-quality cables. There are resistors to cap unused inputs to reduce noise as well. (pictured) In addition to all this, there is a custom-made dust cover for the amp (pictured) It breaks my heart to let this go, but it only gets used a few times each year when I have company. Id like to see it go to a good home. Heavy and huge, will ship in two separate and fully insured boxes to arrive to you safe and sound. Shipping costs reflect this.________________________ Product Description: Features: User-selected amplifier modes, UT (Ultra linear) mode provides greater output power and TR (Triode) mode does smooth and rich sound.
