is it possible to make such preamp?
I'd like to use ef80.I also have ecc82 triode.
It has to have gain,treble and bass knob.
I want to use it to attach guitar with PC line in.
Single dual triode is well documented: http://www.diystompboxes.com/smfforum/index.php?topic=63479.0
Or two dual triodes:

You could add a Fender or Marshall tonestack.
ATM there's not much about pentodes...I got some and will start breadboarding in a while...Until now, you can find a couple of 6418 projects in the gallery. See if they may be helpful....
Got ECC82??? BUILD A VALVY!!! :icon_wink:

Only found this, but it's with a different tube 6AU6 en 36volt DC : http://jonanderson.mn.googlepages.com/tubebooster
Should be easy to design using a space charge tube, referencing that schematic.
Jimmy-H ,this got no bass,gain,treble contrtols...and how is this penthode working on 36 V???? Usually tubes use 300V...all bellow 100V is "fishy" to me

same...9V ...no way this is gonna work
GRRRRRRRRRRRRRRRR :icon_evil:
How'd you say it cannot work?!?!? Just try one!!!
You have to understand that tubes aren't only for those high voltages...12V can make quite a sound!!!
