I used MFJ 811A tubes in my Collins 30L-1 amplifier. Apparently they aren't
suitable for horizontal mounting. Ben, W6FDU In a message dated 12/29/2020

Subject: Re: [Amps] Source of 811A or 572B tubes?
Mike,
I bought a set of 811As for my AL811H around October from Ameritron/MFJ.
I don't know if those tubes will always be available, so I try to keep a couple
of sets on hand.
My other amp uses 3cx800A7s and justifying a replacement set would be
difficult!😂

Hey guys
Fixing up my old backup AL-811H amplifier but down to my last of my last of
my 811A tubes.
rfparts.com is showing no stock of 811A's or 572B's.
Is there another source out there somewhere or does anyone have good info on
when they'll be back in stock of either?
Thanks
