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...

Xiao Nan doesn't just wind his transformers. He builds the cores too. Materials are very inexpensive, even copper, where he lives, compared to the West. He uses premium parts but on the other hand he is not going for overkill where it's not materi...

My essential point is that I am listening to circuits now, not brands; deciding on final implementations as a result. It just happens that I found (stumbled upon) an amp builder who can build inexpensively at quality execution to let me try many c...

Parsons,My amp observations weren't limited to less expensive push-pull examples. I started with Audion Golden Dreams and Audion Black Shadows, a Luxman Anniversary 300B SET and a host of others. What led to the amp circuits exploration was that I...

The V69 clones are rumored to have made it out of Hong Kong yesterday but I haven't yet gotten DHL notice or tracking. Xiao Nan took my batch of amps to Hong Kong to ship just as the protests were getting started back in late April and they've bee...

No doubt that Druids + Submissions will make the initial impression of being altogether badass. Living with that over time and a full spectrum of music can be another matter. But it depends what drives your perception of convincing musicality. Or ...

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 ...
