This is a Yaqin MC-13S EL-34 tube integrated amplifier in excellent functional and cosmetic condition with one minor flaw, the flaw being that the ground sleeve for the right channel of the 2nd pair of RCA input jacks is missing, making the 2nd input pair unusable. The other three pairs of RCA inputs are fine. It is priced accordingly. All tubes were upgraded to Mullards. The right and left channel outputs can be either 4 or 8 ohms and I have used this amp with 4 and 6 ohm speakers without issue. This is a great sounding and positively reviewed amplifier, being sold only because we are downsizing from a large multi-level house to a much smaller, 1-level condo, so I must reduce my current number of audio systems by about half. This amplifier comes with the original box, packing materials, and owners manual. This item can be shipped at the calculated rate or picked up locally in Clayton, St. Louis County, Missouri.

Yaqin MC-13S Integrated Stereo Tube Amplifier. Unit has Upgraded Vacuum tubes installed. Mullard long plate 12AX7s for the preamp, Mullard 12AU7s for the phase inverters and Tung-Sol EL34Bs on the power amp. Each power tube can be individually biased. Amplifier has 4 Audio Inputs (will need a phono preamp if yours is not built into the turntable), outputs are 4 and 8 ohms. Comes with owners/instruction manual. Unit sounds great and looks almost new cosmetically. Tubes will be removed and packaged separately for shipping. Carefully view photos for condition. Shipping is to the Continental United States only, no exceptions. Unit is very heavy due to the high quality transformers.

Beautiful condition. New JJ EL34 power tubes. Tubes have less than 20 hours. The integrated amplifier comes with a custom tube guards. I saw a picture of another amplifier with metal guards and I decided to make my own. They were laser cut and made out of stainless steel. The original screws will be included. I do not use them because sometimes I like to remove the guards so I can see the tubes glow... Dead quiet. Zero hum. It will be doubled box and packaged with a foam machine. The Yaqin logo was green and too bright for my taste and I applied a coat of purple nailpolish and now it looks blue and is not too bright. I have the original blue tubes that came with this amp. One of them went out and I ordered a replacement from the factory but it came a little darker and I decided to replace all four since they said I had bought the last tube they had. ( See screenshot Yaqin factory) I also replaced the (2) 12AX7 The volume pot had a crack and the knob was a little loose and I added JB weld to fill the gap.
