Realistic STA-2080 receiver

sofaspud · 12th April 2011, 06:36 AM

I'm looking for information on the Realistic STA-2080 receivers. I've done the web search thing; there doesn't seem to be much meat on that bone. I need something I can really chew on. So I'm asking the broad question, and might go for more details if I can turn up something here. I have a unit that needs some DIY TLC.

I guess it's not looking too good. There is a previous thread here about this receiver, but again not much in the way of info I'm looking for. By all accounts though this is a well-regarded Radio Shack amp. It's certainly big, heavy, and attractive. I was hoping to find someone who had some previous experience with its internals. I have no documentation for it. I suppose this might be an opportunity to create some info on my own docs, to share with the next person in my current situation.

Hey I have an STA2080. Still have the instruction book. I need to get a 7 amp fuse for it but I have had no luck finding one. I'm in Canada & our Radio Shack stores are now the Source but they no longer have or sell the fuses. Anyone know where they are available?

Radio shack is cellular shack =useless
mouser/ digikey is "the source" in N. america.

Sta-2080 =1. every cap is bad 2. cheaply outsourced Japanese receiver.
3. could be worth something to a collector of classic audio.

Best bet , ebay a "for parts or repair" adcom , hafler , or other 20$ auction.
You would really have something to repair/redo ... then.

Radio Shack used to include the schematic with many of their products. So... does your STA-2080 book have a schematic?
What type of 7A fuse? Is it AGC glass tube, but you can't find the 7A value?

6.3A will do the job

Hi Sofaspud, I have STA-2080 service manual. Let me know if I can provide you Part numbers.

Anything you can provide about the output transistors would be super. Thanks for the offer.
