PRO-82 Scanner

[TXLegend]

My scanner just went out on me it wont turn on or anything, and I think it is the main power supply diode I have in the pic. If it is can someone tell me where to get one and the part number and how to fix it.
If this would not cause the whole radio not to work, then what would?

Thanks In advance for your reply!!

**Also would it hurt anything if i just took this piece out and hooked it up with a straight wire??

 

[TXLegend]

So.... does anyone know what the part name is or number so I can resolve this issue????

Ok Thanks,

I found this but I dont know which diode it is?
RadioShack PRO-82 200-Channel VHF/Air/UHF Handheld Scanner 200-0315 Detailed Parts List

I went to radioshack and got a Zener Diode 1N4733A - 5.1V, does anyone know if that will work?

Better to stick with the original replacement part. Go to someone that is hopefully "knowledgeable" like a manager at Radio Shack and ask him to look up the part under RSU parts.

The part is choke uses to filter AC ripple from power supplies.

Do you know where I can get a choke diode at?

The choke (inductor) is completely destroyed and you state the scanner no longer turns on. About the only way for this to happen is to apply too much voltage. I.E. - I suspect the wrong AC power adapter was used (like 12VDC when 9VDC is the maximum) and therefore, the scanner is destroyed. There's a pretty nice looking PRO-82 on eBay for $28 total. That's what I would do. (And in my "longer than I care to mention" history of owning scanners, I did have a PRO-82. A very nice handheld).

The scanner does turn on when you Jump the two sides where the choke was I am looking for a correct choke though.

I tried searching the web for a schematic or a parts list and came up empty. As you stated earlier, you could just use a piece of wire, but it would mean avoid using the DC adapter. Stick with primary cells or, if using rechargable ones, charge them in an external charger.
