I have owned my MC-10L for over 2 years now and have had no problems. The thing about valve amps is that they are like owning a new pet, you have to know how to treat them in order to keep them happy. As a retired (crinkled) electronics engineer, I know quite a bit about valve technology and maybe this has helped me to keep my Yaqin in first class order. You must regularly check the bias on the output valves to ensure all is well. Well the first thing I did after unpacking the very well packed amplifier was to inspect the valves, after all they are the most delicate items in the package. I personally did not like the way the valves had been manufactured, the internal rivets and metal work did not look quite as good as I had expected and I decided there and then that I would eventually replace all of the valves at a later date. This was an early model, to check the bias meant removal of the top plate which is a pain, thankfully not necessary now as the updated versions have easy access test points and even a trimming tool is provided. There was no handbook with these early units so I checked each valve in order to establish their correct operating points and found all were set very close to each other, that gives you confidence in the manufacturer for a start. I also checked that the alleged 220V - 240V input was happy running on 240V here in the UK and was surprised to find the voltages were spot on for the valve heaters. I run the amplifier into Tannoy speakers and have made my own remote control volume/switching box for the amplifier. The switching arrangement on the Yaqin does introduce some small amounts of cross talk between inputs which is why I made an external unit providing more isolation plus the beauty of remote control. For the money, I don't think you can really go wrong and the cost is far less than trying to build your own amplifier which is how I found the Yaqin in the first place. I was going to build my own but the cost of just the transformers alone was horrific and I doubt if I could have made an amplifier that looks as good. There are issues with some of this manufacturers other amplifiers but the MC10-L appears to be good and I certainly can recommend it. For the more technical reader, I fitted JJ/Tesla EL34's biased at 35mA and replaced the original 6N1's with Svetlana Golds. The difference in sound quality was immediately apparent and certainly made the extra cost worth while. I am currently trying the larger glass enveloped Elecro-Harmonix 6CA7's in the output and they also sound great!

This integrated amp is capable of revealing extremely quiet passages as well as rocking out to the tune of 108db peaks at just 52 watts. A tribute to it's design and value.

One word of warning. I purchased a matched quad of the new JJ KT-77's from the Tube Depot. Within 2 hours of listening to the greatest EL-34 ever made (their words) ,there was a series of very loud pops and electrical noises and smells. No more than 5 seconds passed before I turned it off, but in that brief time, it took out the voicecoil in a Vifa 8" midbass driver in my vintage Harmon-Kardon "Sixty" speakers. Having to buy a new matched pair of drivers cost over $175.00. An authorized dealer i ...

After many years of listening to music from big power amps and boom box speakers, I needed change in my music listening. It was getting stale. More natural was what I needed no turning up bass changing treble just good clean music. After months looking into valve amplification it was mind boggling, good amps varied in price from $2000.00 Au to $12000.00 ( not selling the boat for a amp love my fishing to much ) so now looking for a cheaper valve amp. I said to my son getting rid of the old bu ...
