CMoy knock-off for a Kiwi friend

He asked me to make a small and light HP amp and this is the result. The enclosure is two tone ABS. I have lined it with bitumanised heavy Al foil and...- mwhouston

2N3055 preamp\headphone amp
Here I posted my 2N3055 headphone amp (Woody Pro) and said how much I enjoined it. I was forced to use it because I sold my Tubed HP amp. I bought some Beyerdynamics DT770s (250ohm) but found Woody Pro wouldn't drive it quite loud enough being an emitter follower. So I added my new Tube and...- mwhouston

I have the schematic but at this point will not publish it. The amp is by Oatley Electronics. It uses two 2SK170...- mwhouston
