Before you commit to Takatsuki 300B in your Golden Dreams, I encourage you to listen to the KR 300B globe glass. The standard tube is half the price of the Takatsuki and in my view twice as good. There's a newer premium KR 300B for the US market o...

Some catchup:Our brainless administration's dumb trade war with China has slowed shipping of my last couple of custom amps. I expected them earlier this month but now it will be sometime in June. Shortly after I get them I will complete my amps su...

Which Whammerdyne? Would you spend the cash for the Parallel Single Ended model? I'm guessing not.I haven't heard the Whammerdyne. And I have only an academic interest in it because a 2a3 SET amp just doesn't have enough shove, even for 101db/w/m ...
