ATP4
Hello,
A long time ago, I've bought 4 ATP4's, not knowing what is was. A few years ago, I've build my first tube-amplifier with ECL86's. But the ATP4's are looking great ! Is it possible to use them for an small audio-amplifier ? 1 or 2 watts output power for example ? Mayby by using it as a kathode-follower? I mean: The anode connected to the + supply, and the kathode connected to the output-transformer ? ---------- U+ | O ATP4 | ___ ) ( speaker ) (___ | _______ U- Why is there a + en - sign at the filament ? Isn't it possible to use AC for the heating ? There isn't much data available on the internet about this tube. I Really hope you can help me further with this. Thanks a lot in advance, Marco Loos |
