Well my dad dug out his channel 9 walkies yesturday, and one of them wouldn't charge up.
They are the old style battery pack that plugs into the 110v house socket and stays there for 16hrs then powers a big handheld emergency frequency two way radio.
I got the repair manual all printed so I have the shcematic to share wtih you if it gets dicey.
It has a blown 270 ohm resistor and it looks like 3 diodes from the rectifier pack are gone.
I started looking for parts in my small collection, and found a 270 on the auction site.
I can't seem to find any diodes that interest me...
The schematic (which I will share when I take a pic of it) is clear and easy to follow, but I just wanted to see if you had anything to add before I heat up the gun and start burning things....
This charges a pack of 2 - 6.5v nickel-hydrides, and has a 4 diode full wave rectifier on a small board amid 2 resistors and is designed to deliver 18mA.
ahem...does the diode type and size effect the power output ? do I need to know what kind was in it, because I haven't seen any like this before... they have a white band and an orange band, and all the resistors seem to have the same markings.
Can I use a component diode pack rectifier instead?
