selfie for scale

I know things have been slow here so I am stirring up the bottom of the barrel for some content. 

 This is a new first order "Proof of Concept" idea that showed up the other day.  It is in the early stages and might be a total flop but people have been badgering us for this solution for years.


If it fails, this is all the world will see of it.  In our typical fashion, we are approaching the concept from square one and cautiously moving on from there trying to learn.

Hong Kong DIY

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.
