	I think you're doing it backwards.  ECG is a company that produces
replacement transistors.  They have a big catalog listing 2N to ECG number
mappings, not the other way around.  Typically an ECG part will be a direct
replacement for a whole slew of 2N parts, having the same pinouts, equal or
greater beta and Ft, and max voltage and power ratings which exceed those of
all the 2N parts covered.  NTE electronics seems to also make a whole line
of drop-in replacements, with the same numbers as the ECGs.  For example,
the 289A and 290A are complementary (ie NPN and PNP) general purpose audio
frequency amplifiers.  Any serious electronics supplier (look for places
that cater to the TV repair trade) should have a good chunk of the ECG
and/or NTE line in stock.  You want to get the ECG Master Replacement Guide;
it's a phone-book size catalog showing everything.  Probably costs $5 by
now, but worth it.  If you can't find a dealer, try calling one of:
