Need help: Looking for ECF80 preamp schematic - Click HERE for Original Thread
Mrpong
Hi

I'm looking for some preamp schematics that use ECF80/E80CF tubes.

Thank you in advance.

Also do a search on 6BL8 which is the same tube.
There were certainly some 6BL8 preamp designs in the "Electronics Australia" magazine back in the 1970's. Will check my file tonight.
Cheers,
Ian
