Default ecf82 pentode instead of ef86

Anyoune tried the pentode part of ecf82 instead of ef86?
just found one ecf82 in the drawer.
I saw it is used for tremolo oscilator in vox ac10, but I am actually looking for the sound of the ef86 channel. (ac15 heritage)

I built the latter with an ef85 pentode, it has a deep bass, mild and vibrating tone, but all the highs.. are gone. It sounds just.. natural.
No compression and attack on the highs
I even better like it in triode mode - natural sound.
A good overdrive in the low to mid range (pentode), but no sparkle ):

ef85 isnt realy a usefull device as its made as a automatic controll . once the signal gets strong it compresses the signal .

ecf82s where used in TV's would be brave to try it . but it can also be used as a phase splitter New Phase Splitter

im looking forward to hearing what you discover as i have a box of about 50 of them
