Default In a search for a 6CG7 line stage schematic

Hello,

I have a couple of 6CG7's and I wonder if anyone can present a line stage circuit where these tubes are used.

Hi,

Also a couple of schematics for line preamps on Patrick Turners Web site. See link below.

{Note page down to pre-amp section right at the bottom of the web page}

Cheers,

They are basically a 6SN7 in a small 9 pin bottle. Any of the multitude of designs out there for 6SN7s will work.

Thank you all!
Im reading about Aikido at the moment, and i have a question. If i understood well, I can use different tubes for input to achieve more or less gain without changeing passive elements?
I know i should change the filament voltage depending on type of a particular tube, but the catode/anode ressistors remains same?
