I have looked at the F2a in the past for certain applications - it's certainly a premium valve. However, why the reference to the 300B ? It's an indirect heated pentode - more like a premium KT88 than anything else.

Hi Mark.

The reference is with regard to the musical presentation, similar to 300B though in my experience, the F2a has more ‘get up and go’ and for want of better expression, ‘atmosphere’. Sounded wonderful in my Shindo amplifier - why did I ever sell it!!

Ah, OK. So does the Shindo use them as pentodes or triode-strapped ?
I'll have a look if I get chance.

F2a’s are Tetrodes I believe.
