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 |

You could try it in plain 'ol SE.. or maybe PP.
but with 5w max Pa, you're not going to get much juice out of it "Marco Loos" wrote in message om... Hello, A long time ago, I've bought 4 ATP4's, not knowing what is was.

Thanks a lot in advance, Marco Loos Might be a good driver, you should use a power tube as output, maybe an 807 or 6V6. |

Thanks for the advise, but now I still have no shematics or more info about this ATP4. Is there anybody with knowlegde about this tube ? - Marco |
