EPT690010Z problem

[space cowboy]

turn it on and the volume is immediately loud and crackling. it's so loud at no volume I just turn it off, it's too loud to even just listen.
any thoughts?

Defective pot or shorted wiring.

nice. I was hoping for something easy like that. swapped it out today after 2 weeks without a radio. probably look at it monday.
hope I can find the parts at the local shop.

Ptobably not. But first, you have to make sure that is the problem. The parts for this chassis are available from RF Parts - for starters . . .

Bad volume pot would be my first guess. You can test the resistance with a multimeter to see if its working correctly.

I gave it a quick test with the multi and as soon as it turns on there's no resistance through the whole volume range.
now I just have to get it out of there, and figure out another 13$ purchase to meet the minimum 20$ order.

Before you spend the $$$ on a new pot, disconnect the pot and determine if the short is in the pot or the board. Hard to imagine how a carbon-based pot would short out.

I will, but I figure a board or wire short would show 0 ohms with the switch on and off, not just when it's on.

 

[space cowboy]

unwired the switch, and as soon as you click it on, no resistance through the whole volume range.
it was a pain trying to rack up $20 at rf parts so I ordered off ebay for 12.95 total. seller is in alabama.

all fixed.
though ordered on ebay from barkett electronics, they do have a separate webpage - http://stores.goldeneagleradios.com/ . ordered sunday, shipped the correct part monday.
