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

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 ?

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,
