Nigel,
There is no reference to any suffix on the data sheet I have. (I can
fax you a copy if you e-mail me with a fax number.) Also, I'm not aware
that RCA ever used a 'multiplier'. Texas Instruments did on some
devices (like the TIP-31/31A/31B/31C) but I'm not aware that the suffix
was a multiplier. The data sheet always listed the specific voltage for
each version.
