Tony,
Thanks for the suggestion. I'll work on adding a drop down box to select
the tube family. For the short haul I'll just increase the AB2 to 1.65.
Not sure where I might get the tube family info, so if anyone can
help I'd greatly appreciate it.
Regards,
Larry N5BIP

Larry,
Your Plate Load calculator for an AB2 amp seems to be using a constant
of about 1.55 which might be a bit on the low side. The 8877 might be
close at 1.6 but a number of other tubes would be closer to 1.8 to 2. I
wondered what you used to determine the constant? If there was another
input field to select a tube "family" to set the constant it might be
helpful.
Good job!
