Yaqin MC-100B Tube Amplifier Review

If you’re looking for a good tube amp that comes at a decent price, this article is for you. In this Yaqin MC-100B review, you’ll find everything you need to know about the tube amplifier. 

To make the search process easier for you, I’ve compiled all the features, pros, and cons as well as buyers’ impressions to guide you towards making the decision. So without further ado, let’s dive in!

Great Sound Quality for an Affordable Price

The first impression of the Yaqin MC-100 is that it does come at a fair price that is typically unheard of in that class. 


It produces a smooth sound with richer audio experience all the while staying powerful. It comes with multiple modes that allow you to adjust between sound quality and power.


For example, you can adjust it to the UT (Ultra linear) mode. This one provides a greater amount of power, allowing you to blast it at a higher volume.

However, it also has a TR (triode) mode, which is responsible for making a rich and smooth sound.

Handcrafted Design

One of the great things that you’re going to love about this tube amp is that it looks as good as it sounds. 

The Yaqin MC-100B is arranged nicely with a design that is fairly compact. The model chassis is handcrafted from durable steel and heavy-duty aluminum. This gives it an excellent level of sturdiness while staying aesthetically pleasing to the eyes.

The handcraft improves the sound quality because it decreases the loss of the sound by avoiding industrial sharp welds. Moreover, the tubes glow nice and warm in the dark, which never fails to mesmerize me while enjoying music.

Additionally, the output transformers are made with enameled copper and Japanese silicone steel sheet to give a dynamic range output.


The tube amp has some drawbacks that many buyers have noticed. For example, being a Chinese device, it comes with a different voltage that isn’t suitable for American households.

The Yaqin Mc-100B is a 220-volt device, which isn’t compatible with any house or studio that operates at 110 volts. Users who weren’t aware of this issue had their fuses blown in a significantly short amount of time.

However, the solution to this problem is fairly simple, all you have to do is to connect the device to a voltage regulator to guard the fuses against the different current.


What Customer Reviews Say

The Yaqin Mc-100b Tube Amplifier currently holds a fair amount of reviews on Amazon. It has about 14 customer reviews and an overall customer rating of about 3.4 stars out of 5.

The majority of the other reviews are mainly 4-star ratings, which is more towards an excellent product than a bad one.

Similar to the ratings, the general tone of the reviews was also mixed.  A lot of buyers claim that it sounds great even when they’re using it for hours every single day for weeks.

For example, one buyer claims that the device has been running like a charm for the 4th year. Since the device comes from china, many users said that it came with 220-volt compatibility only. However, they also noticed that it’s easy to fix this issue.

As for the negative reviews, it was focused on some points regarding the device. For instance, many buyers complained about the fuses and claimed that some of them started making some popping sounds after a few months.


With that said, you have a complete Yaqin MC-100B tube amplifier review with everything you need to know about the device.

In terms of sound quality, the tube amp produces a delightful sound no matter the genre you’re playing. The pure sound and music will take you back to the authentic time of analog tube amp

As you can see, a lot of buyers complained about the blowing fuses because they weren’t aware of electric spikes produced from the overseas 220 voltage. 

If you want to keep your device running for years to come, you need to buy a voltage regulator. This will guard it against these spikes and keep your device running without popping sounds.
