You brought back old memories of TBA810, LM381 etc. And the
infamous Delhi make cassette decks (Chawla mechanism etc). I
was so thrilled to get a hydraulic soft eject Japanese mechanism with
a glass ferrite head for my DIY casette player -
moved from a discrete pre to a LA3161, and amp was 2 * TBA810.
Even glass epoxy PCBs were such a rarity.
The 2N3055 based Philips 40W, or the STK amps
were too expensive for me.
Of course, I went through the obligatory bird bells, running LEDs,
misc 555 ckts, digital clock etc, AC128 based pocket radio and so on.
A huge discovery for me was TTL and CMOS (74xx and 4xxx)
series ICs.
I think Elecktor started the Indian edition in 1983?
I really lusted for the stuff in the UK editions and
the Elektor books (one on the micoprocessor kit and their
circuits collection, including a full TTL clock with alarm etc).
Fantastic...remember the Chawla mechanisms, saved all my pocket money to buy one for Rs.150 (think it was) but it was so unreliable. I've built amps with AD149, AD161/AD162 and even used the STK amps...all DIY
