While inside a SONY (ICF6700L) Radio, I rewired it to trickle charge the
batteries from mains (something you can do to all batteries to some extent) and
also change the 9V DC input jack from -ve centre to + ve centre & 12V DC.
I also cut some PCB track and added a 200mA slow blow mains fuse as there was
no fuse or internal thermal breaker in that type of transformer!
The 2 10R set the charge current. Due to the DC jack -ve switch and the lamp
timer kill complications, it was it was not possible to simplify the circuit.
It is nothing like as straight forward as I had hoped.
Why Don't U send an interesting bul?
