More Clean Headroom from 5F6A

[philster]

Hi Guys
I recently built a 5F6A Bassman and have been having much fun tweaking it and gigging it. I've changed a few values of caps to get the sound slightly more JTM sounding and love it. I get a great rhythm sound but when it comes solo time can't get much of a volume boost as she saturates.
So - I'd happily sacrifice some of the amps overdrive for a cleaner tone and more volume ( I can use a tubescreamer to get things in the zone). Any suggestions on how I can achieve this? I am running a 12AY7 in V1 as I love the sound. Should I return it to 5F6A specs or can I tweak other places to boos the volume slightly?
Cheers
Phil

In my experience a properly functioning 5f6 is one loud amp, usually too loud for most gigs if you want some breakup. What mods have you done?
More efficient speakers is one possibility.

What tubes are you running?

Do the voltages all look to be within spec? Maybe get a complete set and post them here...

Change the tail resistor to a 68K...
