I need a simple schematic with 6J1P tubes

kosmin227 · 18th December 2005, 08:51 PM

I have 4 new tubes(they are russian tubes

) and I want a tested schematic with them and if it`s possible with a pcb.
I know these tubes are equivalent with ECC88 or 6DJ8.
I also found a schematic named Cavalli Jones headphone amplifier(Cavalli Jones ) but i don`t know how to connect the tubes and how to design the pcb. I also mention that my tubes are very small and they have just 7 pins and in that site I saw that have 9

.
I really need help because it is my first project with tubes.

6n1p pins out the same as a 6922 and it will substitute for the 6922 SOMETIMES, IF the 2X heater current is available.

The 6j1p is a 7 pin pentode. 6j1p Data Sheet

The reason you are not getting many replies is that there are SO many choices if you search for 6922 or ECC88. Also, you have said hardly anything about what you want to DRIVE with those tubes. Drive a solid state power amp? Make a headphone amp?

EDIT: Sorry, I see I misread the thread and you are looking for a project for the 7 pin pentode instead of 6922 equivalent
