6 channel unity gain FP3?

Posted by xcortes on July 2, 2008 at 08:22:06:
I need a 6 channel preamp. I already have a six pole 11 position make before break switch. The easiest would be just a 6 channel "passive", maybe 10K, feeding the amps and the subwoofer.

However I was thinking of building an active stage modifying a FP3. I would install a third 12AU7 and use only one section of each tube as a cathode follower. The first question is: Can the power supply support a third 12AU7?

thanks

ps I'm, of course, talking about a non-extended FP with the OD3 regulator.
