Its low gain and is in need of every bit of oomph in the bass. DC and low Zo helps it, full DC path. IMHO of course. Having heard the F5 with DCB1, 6V6 as buffer, on my 95dB speakers they are closer in musical weight. F5 needs 12dB+ line gain and 95dB+ 8 Ohm flattish Z speakers to start partying, IMHO again. ~ 50W single output pair Andrej's SSA goes ''bigger'' easier on lazy speakers but its not a finished simple form DC steady kit yet. Apples to oranges VS F5. DCB1 was firmer VS #26 also on Baby Huey with Hashimoto OPT in Vgeorge's Lynn Olson's Beyond The Ariel line of thought 100dB 4 way system (90Hz up, subs active 300W). But #26 had a golden like harmonic hue (was not there in source) very beguiling without pushing back clarity. Still a bit shallower even with line level XLR OPT and autoformer pot. No DC path again, bass & midbass love straight paths it seems.

Thought I could give you a wider subjective frame to perplex you more.

no need to do that, just state your facts, and everything will be fine

still dont understand why BA-3 works better with 6V6 than the F5
I really thought it would be the other way round, due to the known F5 lowish gain
some say they miss the 'grunt'
but I guess it also relates to your speakers, and listening 'habbits', music, etc etc
