[Amps] Source of 811A or 572B tubes?

[Matthew DeGumbia]

RF Parts has a new supply of tubes that are undergoing testing.They
may have them available after the first of the year.Contact
sales at rfparts.com and get on their list.They will also have 572B tubes
and possibly the 811H-PRC with the graphite anode.So RFParts may be
another source.

 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

 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
