Domnic uses full set of transformers from J&K Audio Design - the GM70 output transformer, separate power transformer for B+ and filament transformers.
Enjoy the pictures - very nicely done!
Short and sweet comments from Domnic!
The hum & hissing are not related to the transformers but the design of the amplifier. After several emails between Domnic and us, this issue is fixed by adding some additional circuit to the amplifier. The amplifier is as quiet as the deep wide universe now, and he's a very happy camper!
Some GM70 amplifier internal picture for those more technical minded. A lot of audiophile components are used, such as Mundorf electrolytic capacitors, Jensen PIO coupling capacitors, Kiwame carbon composition resistors and of course, full set of J&K transformers.
Again, this is as honest as it can be - review from real user! No alteration of the customer posts have been made.
