Model 10A tweeter blown.

Daddio911

Hello, I am the original owner of a break the bank Model 10A's. Yes I spent all my college money on these speakers. Yes the rocked that little dorm room. I seem to have blown another tweeter. Years back this was the norm. The silver one is blown. Can I get a replacement that is the same as original or is there an upgrade? Any advice on upgrades would be greatly appreciated.

Peerless tweeters show up frequently on eBay. I prefer the 7714xxxx ones over the 5514s, but the 5514s aren't exactly crap. Another way to get them is by buying old Model 5s or 4s that you can then scavenge for parts. Might even get some silver basket MWs that way for spares.

PS: How did you blow tweeters with a 1 amp fast blow fuse?

I found this as a potential replacement. Your thoughts?

Have you checked the fuse?

BTW, the all black tweeter is the Peerless. The silver one is the SL1000 and is not a match for the Peerless.

Daddio911

Yes I did check the fuse. The speaker has power but is cutting out and very scratchy. Best way to describe it is blown. The silver one was a replacement by the shop I purchased them from years ago and its the one that is blown.

Thanks

Try cleaning the ends of the fuse and the fuse holder clips with a contact cleaner.

Regardless of the outcome the SL1000 should be replaced with an original Peerless as the SL1000 has a very different sound.

Edit: In a pinch you can use the eraser on a pencil to clean the fuse ends and fuse holder clips.

I don't have any first hand experience with those ones from midwestspeakerrepair but maybe someone who has tried them might weigh in. I'm doubtful that they measure up though.

Do you have an outlet for the peerless replacement?

F1nut

For an original Peerless your best bet is eBay. Make sure it has the tiny hole in the center of the dome.

Here's one. Not cheap. Looks like a 5514xxxx even though the number is pretty darn smeared: https://www.ebay.com/itm/peerless-vintage-1-soft-dome-tweeter/264655593618?hash=item3d9eb3e092:g:P0wAAOSwC4xeXx8I
