I'm using something like this- sounds very clear!
tube is ECC88 ?or you can see it:

Hello
Nice schematic your 6N23P hybrid amp.
I have lot of new old stock 6N2P-EV tube from Russia, same than 12AX7 but with a different filament connexion.
So I would like to use my 6N2P-EV in a hybrid LM3886 amp.
Do my schematic are good ?
But I would need suggestion of values for RK resistors.
Thank
Bye

the amp is very goood !(about my schematics ,you can try it)
as i know 12ax7 and 6n23p have different characteristics and not only the filament conection is not like in 6N23P
your schematics is good too but is beter if you use 4,7u cap as input capacitor
this is my pcb for my amp

Hello
Looking at the spec of the 6n2p-ev, maby (in my schematic) 90 volt of anode voltage are a bit low ?

Very interesting pcb, show us also the psu please
Green Marlin said:Hi jazzman06 sorry but i don't understand the dimension of pcb.
I try at printed the pcb but at 100% is very big , at 50% the 3886
not insert in the hole, is possible have the right dimension?
You sold the pcb.
thanks for all
Sergio
Green Marlin - i have attached a rar archive that contains lay file , you can open it with sprint layout v 5.0
and print it from it

Green Marlin- can you post photos of what you'll do ,or mail mail me jazzman06@rambler.ru
I'd be interested in a tube phase splitter for use in the BPA-300 amplifier. This could replace the expensive Jensen or Lundahl input transformer and or opamp input phase splitter that is necessary in this amplifier. I think a toobe would be a much better choice then either of the other routes. There are already kit amplifiers for sale from China via e-bay similar to what you guys are showing above.

I don't see how you could go wrong for 46USD!! At least thisn is not a stolen circuit belonging to someone else...
