Hi RATs!


Some people are having a bit of fun, occasionally.


You could never imagine that, but, it happens, anyway.


Almost as if you are not the Supeme Being you assume...

While there's no accounting for taste, on the other hand: Anyone who
thinks Class AB2 bears any relationship to music deserves to have Bret
Ludwig as his only friend.


There was a time when anyone with a sense of style wouldn't set foot a
beach without a battery powered radio to acompany they posing. Because
the batteries didn't last too long with high draw, the best audio amps
in the portables has class AB1 or AB2 circuits biased almost for class
B. Nobody complained much and nothing got much better when the
Japanese invented portables for the beach with nearly class B
transistor circuits.

But the early car radios had class A tubes and then class A transistor
amps; just one TO3 transistor with 12V feed and 1 amp idle. Same Pda
as a 6BQ5
Sound was OK.

But I once repaired a Lennard amp with 8 x *L34, Ea = 900V, Eg2 =
450V, and PO = 450W class AB1, and with very little class A. Only
12dB global NFB. It sounded very well in a hall with 300 ppl - much
better than a huge bjt amp.
