After many late nights and lots of tinkering, I’m pleased to announce that the retro audio project is finally completed. Also worth noting that instead of sitting with its guts out on a messy bench, this particular setup is properly mounted in a car (the savanna banana, to be precise!)

This is cassette deck build number two, a KP-717G deck from 1983 with added attenuator circuit (to bring the auxiliary input down to a level which the onboard pre-amp can handle), outputting through a CD-5 graphic equalizer into a pair of (hidden) amps.

At the moment only the front speakers are functional… they’re fucked and need replacing anyway, as evidenced by the awful crackle in the video – I won’t hook up the rears until the two-seater conversion parts arrive.

which should be sometime in the next few weeks. Then I can hit the streets with some phat beats playing, haha.

Made some significant progress today with the retro audio project – one of the decks is nowe fully modified for AUX-in operation. Here’s the quick’n'nasty rundown and demonstration video:

The next logical step is to create some sort of circuit to allow full switching between cassette and AUX, but that involves pulling one of my expensive functional cassette players apart so I’ll come back to this in the new year.
