Unabel to find any Audio Transformers (the little cheap ones) 500 ohm to 8 ohm

The only one's listed on eBay are high end (fairly to extravagantly high priced) transformers. I just need a little 4 legged 500 ohm to 8 ohm audio transformer. All my catalogs seem to offer little help. No need for the C/T like the one pictured....

Can anyone say the "code" or perticular name for the AUDIO TRANSFORMER ?????

the small size and ratings (500 ohm to 8 ohm) normally means it isn't going to handle anything above audio frequencies.

Try the electronicgoldmine, you may find what you are looking for there...
Goodhart (author)  comodore7 years ago
I have bought quite a few things from them lately, but haven't been able to find these there....yet. :-) But I always keep them in mind. Thanks for the reminder.
Yes, and the prices are very good, a lot of stuff is so cheap...
Goodhart (author)  comodore4 years ago
But you also have to watch it, they make out on things that are "cheaper elsewhere" on occasion

The specs on the Radio Shack transformer are 1000 ohm center tapped primary. That should be two 500 ohm coils, right? The secondary is 8 ohms.

Yeah, same as the one I got from All Electronics

If you lived in UK, Maplin sells them cheap...

at one time I had quite a supply of them :-) Well, I got a pair of them for a little over a $1 so that wasn't too bad.

Thanks, since the 3 local stores didn't have them and said they could not get them I didn't think to look at the online store.

I did not look closely to see if Radio Shack stores have these audio transformers in the store or not. They always did in the past. Just because they are listed on-line does not mean they are not also in local RS stores. Too bad about the price increase. Last evening I was in a Lowe's and saw a power tool I had seen in another Lowe's the evening before for a "regular price" of 20 percent less! Caveat emptor!
Goodhart (author)  Phil B7 years ago
Well, I asked the clerks (mistake) and gave them the specs I needed (bigger mistake; since that only confused them all the more) and they hadn't heard of them and said they couldn't get anything they didn't carry (another big change....in the past they could always order a cross referenced part *sigh*)

The folks at allelectronics.com have a similar trannie for $1.35, although there's always the minimum shipping charge pain...
Goodhart (author)  gmoon7 years ago
Thanks again, I went ahead and ordered from them having done so in the past along with a bunch of other things I needed might as well make use of that standard $7 shipping charge :-)
gmoon Goodhart7 years ago
Yeah, I keep a "running list" of stuff, so the charge isn't so bad... (but I always forget something. ...doh.)
Goodhart (author)  gmoon7 years ago
Yeah, so do I :-)
Goodhart (author)  gmoon7 years ago
Thanks, let me see if this is closer to what I need.
I have one of their catalogs but it is not a recent one, and they didn't list them in there.
Goodhart (author)  Goodhart7 years ago
Wow, 2.99 the last time I bought the little ones at this rating, you could get a bag of 10 of them for that. *sigh*.

. How about this guy? Not a recommendation, just the first hit when I Googled "Audio Transformer +cheap".
Goodhart (author)  NachoMahma7 years ago
I will check.....seems I get different lists then others do when googling...I used the wording audio transformer
LinuxH4x0r7 years ago
how could you test them to find out if they are right? i might have a couple laying around somewhere
Goodhart (author)  LinuxH4x0r7 years ago
I suppose I can't just measure the resistance.....I don't have an impedance meter....I am not sure.
