Yaqin MC-13S
Minty integrated tube amp. All original tubes with 6CA7-T blue output tubes. About 30 minutes total time on all tubes. All functions are perfect. Amp is quiet and powerful. Here are the specs:
YAQIN MC-13S is considered one of the best class A/B integrated amplifiers in 2021 by review group of amplifier experts in USA and Europe. Of all the components, the transformers stand out most. Both the input and output transformers are very high quality. It starts with the oxygen-free enameled copper used in the windings for the transformers cores. It ends with the use of 35-milimeter Japanese steel sheet employed in the building of the laminated stacks surrounding the core windings.
Additional Characteristics on MC-13S amp :
manual biasing.
4 switchable line input.
Convenient analog VU-meter.
Spec: Output Power: 40W + 40W (8Ω)
Distortion: ≤ 0.9% (28W)
Frequency response: 10Hz-60KHz (± 2dB)
SNR: ≥ 85dB (A weighted)
Load impedance: 8Ω or 4Ω
Power consumption: 240W
Sensitivity: ≤ 0.26 V
Tube: EL34 x 4, 12AX7B x2, 12AU7 x 2
Dimensions: 470(D)315(W) 175(H)mm
Input Power Voltage: AC110V/220V 60Hz/50Hz (110V/120V/230V/240V)
Net Weight: 22 kg
The amp is hooked up to speakers and can be auditioned most any time in my home. You will not be disappointed. Amazon price is $1000.00 My price is $800.00 firm. Would prefer a local buyer as the amp is quite heavy and shipping is going to be high. I am in Pacifica just off Highway 1. This is amp #4 of 6 I am selling.

Given the power output it is Class AB.
Not the first time Yaqin has lied about the amplifiers class. I have one on my living room floor.

I copied the specs and never noticed the mention of class A. Of course it's A/B and I have edited the posting to reflect that. Thanks for noticing. Not sure if it's Yaqin or another source that's lying. I found the spec sheet on a webpage online.

The specs for mine (a bigger bottle but we converted it to EL34) was rated at 40 w Class A, it was bog standard Class AB.

Actually the Yaqin website only quotes UL or Triode operations on their larger amps and there is no claim of Class A. Someone along the distribution chain probably embellished the specs.
This is a problem with most Chinese amps. The manufacturer gives specs and the distribution chain makes marketing claims above and beyond that.
There U.S. distributors are notorious for this kind of thing. We went through this with Japanese audio products in the late '60's and early 70's. Highly inflated power and distortion specs were the rule!
