What's the best tube amp one would like to have, wildest dreams come to life? Before I knew anything about the inner workings and started to build my own I tried think of what tick boxes such a beast should have: - be able to run any sort of popular DHT output: 45,46,2A3,300B,PX4,PX25,AD1,6A3,VT62 etc. - dual input tube with mix and match. Usually it's one tube per channel resulting in mismatched sections after a while. With one tube doing the first stage and the second one the 2nd stage one can tailor to the wildest dreams. - speaker output because why not - low and high gain/impedance outputs - fancy components inside, PIO caps, stepped pot, Japanese iron, dutch cables - adjustable everything with check points - built to last by a pro A good year a half ago I came across this blog post: http://easytubeamp.com/woo-audio-wa5-vzglyad-snaruzhi-i-iznutri/ Having re-bought my old Woo WA5 I yearned for an upgrade. Next to the Stellaris it was slow, thick and rolled off. Had it's moments yet it was clear a 300B should sound better. Reach out to the builder and over a year ago, he was crazy to accept my request and I sent my woo for a long journey to literally the other side of the world in Vladivostok, east Russia. Several days ago, got it back, meet my crazy do it all one of a kind amp: There's nothing really from the original apart from the chassis, new tango ISO FC20S OTP, even the power transformers has been re-wound just for HT with three more for heater duties. Hot 8W Sophia Royal princess 300B with a mix of TS RPBG 6F8G and Visseaux 6J5 Cool 4W Elrog 300B with two of my favourite tubes, now complementing each other, tube fusion: I'd really like to try this against a WA33, perfect British combo, BL63 and ECC32, 2A3 running with DNA spec: I'll let it run in for a while, savour tube rolling at its finest, then use it and the Stellaris as benchmarks for my own build.
