For me, an AC127 was only 1 week pocket money !Transistors like the AC126 were just displacing the older OC types back in
the days when I had to save up 2 weeks pocket money for a single AC126.
My first AC127 (s) were on a pile of scrap TV boards, all the IF modulesian field wrote:

But I have to take the bus, which cost around 1/2 week pocket money !

And I vaguely remember some AD161/162 TO-66 complementary
output pair. Hah ! Pd = 6W !
A Japanese derivative according to one source I found. But barely different. Do"Eeysore"

** AD161/2s were NOT made using a TO66 pack.
The pin and mounting hole spacings are wider than TO66 & the pins and base
plate are both much thicker.
The pack designation is an obscure one, given as " SOT-9 " in some spec
sheets.

Do you NEED to pick nits ?
My first one was to build a rain detector (with also a bc138) when I wasMy first AC127 (s) were on a pile of scrap TV boards, all the IF modules
were missing but at one end was a complete AF amplifier with germanium
complementary pair output.
By this time TO220 silicon complementary pairs were filtering onto the
market, so I upgraded a pair of the TV AF amplifiers and used them to
modernise an old tube stereogram.
