I first met Ngan when he became interested in Stephie's LR phono and that was close to 10 years ago. Since then we have become friends and he is one of the guys that is willing to try everything... that is not a typo... he does try everything.
He sent me these pics of his latest build which aside from the filament and power transformers use all nickel transformers. As I recall filtering is a nickel choke input filter with a second nickel smoothing choke. The driver is an 841 loaded with a nickel plate choke feeding a 50/300B with 5K nickel outputs.
I can't wait to see how it looks in 10 years when all the brass patinias up.
