6-slot sound issues

NEgO MANIAC · Dec 3, 2005

Why does my 6-slot have to be on for a while to hear the sound? Normally it takes an hour and still even isn't all that loud. I took a look at the pcb and diddn't see anything burnt or broken. Is this a simple component fix? Also, the left side is louder than the right side.

I had the same problem with my six slot pcb. I changed all the capacitors in the sound circuit and it came up good as new.

You probably won't find 'em at your local Radio Shack store anymore... www.digikey.com or www.mouser.com are great sources. I tend to use Mouser since they have a warehouse on the other side of Ft. Worth and I get my parts in 1 to 2 days with cheap USPS shipping

For local places, check the Yellow Pages or ask a few local amateur radio operators. They know where the parts stores are.

How do I know which ones are for sound?

The caps around the HA13001 are for the sound (i believe), changing the 470uf and 220uf caps fixed my problems. I still changed all the caps on both boards, as the electronics tech at work said capacitors fail with age and the six slot pcbs are around 15 years old now. They are a good place to start.

Change the ones that are cylindrical in shape... Be careful! They are polarized and may POP if you put them in backwards. There's a line down one side that usually marks the negative lead.
