My radio shack 150 in one electronic project kit (cat
number 28-248, maybe 1976?) contains a part listed as
an "Integrated Circuit". Model number BA-302 is
listed and that's what's on the part. It's a 7 pin
inline package. The text mentions it to be a "ring of
three" amplifier.
I've been having quite a bit of fun working with this
kit, never had one as a kid, but this part has me a
bit baffled. Internet searches haven't turned up
anything useful. Anyone can help? I'd really
appreciate it.
Thanks, Jim

I had the 150-in-1 as a kid (and still have it)... ISTR they put the
equivalent circuit either in the manual or on the cardboard face of
the kit... it's a simple 3-transistor amplifier, and I've never seen
anything like it in the wild, but perhaps it was used in FM radios of
the day?

Interesting that there doesn't seem to be any data out there on this part. If
one of you guys finds a datasheet, feel free to forward me a copy and I'll
put it in the pile.

The 160-in-1 also has it.

It was used in japanese am/fm radios in the same timeframe. A similar
part
was the uL703 if memory is still online.

Jim,
That part is the same as an NTE-1431. Same 7 pin inline package. I have a
PDF datasheet if you want a copy. Let me know and I'll send it offline.
Best regards, Steven

I had one of these as a kid. I started out with a 65-In-One when
I was about 6 or 7 years old, and got a 150-In-One a year or two
later. I absolutely loved those things.
I remember having seen a schematic for that chip; I think it was
in the manual. Since then, though, I've seen no mention of this chip
(or anything related) at all.
