Yaqin MS23B Upgrades

It’s easy to assume that every valve amplifier delivers good performance, but sadly, some fall short of expectations. One example is the Yaqin MS23B. Straight out of the box, it can leave music feeling lifeless and uninspired.

Fortunately, Les Carpenter has developed an excellent modification that transforms this phono stage into a true performer.

Check out the photos below to see some of the modifications I’ve undertaken to bring this amp to life.
