Over the past 12 months, I have built a pair of GM-70 monoblocks. During this process, I sourced many of the transformers (filament, power, chokes) from J&K Audio Design. I can say, without a doubt, that in my experience, these transformers are first rate. Excellent build quality. Reasonable prices for a custom transformer supplier.
By comparison, using other brand transformers, I continually experienced mechanical vibration and hum. With the J&K Audio Design transformers, there was absolutely no mechanical vibration nor hum. Dead quiet. Silence. Rock solid.
Additionally, the engineer at J&K Audio Design (Jolin) is very helpful and willing to educate this newbie.
Highly recommended.
