Finished my Joplin 2A3 PP and am really enjoying it. Would like to improve the soundstage to get the most out of my Khorns and room.

Interested in the Django and saw the MAD octal 6SE preamps. Any suggestions / comments?

thanks

Frank´s 12BH7A

I built Frank´s 12BH7A WCF. No gain, more (non exotic) components in the signal path, but the gain in soundstage and musicality (or whatever you want to call it) was and is pretty rewarding.

Beware this preamp is not available as a kit. You have to build it from scratch. Schematics were kindly made available through Frank for this forum (search for frank´s preamp, 12BH7A, etc).
