Is this an amplifier brand my friend?

Because i normally associate SWR with Standing Wave Ratio, some measurements made in Radio Frequency transmission Lines that may be matched or mismatched related the transmitter output impedance.

I suppose you are telling something about sound, am i rigth?

Can you post more informs, pictures or models, to help us to help you.

regards,

Carlos

There`s nothing to worry about, you are welcome, and i have just learn that exist

This Guitar and Bass factory.

Leson started producing phono cartridges in 1968, and they had agreement with Shure, being the best they made the Shure 44E copy.

Also they represent and construct microphones, beeing the best model something alike Shure 58 microphone.

They are not the best in the market, normally they produce cheap things as i can remember......but i can be not so well informed, as my country is fourth world, and my place is the fourth Word of the fourth World related electronic supply...... beeing kind, Brazil Northeast may be fifth world related electronics parts, beeing the same as the whole country related other things.

They use to produce those cheap Piezo Electric tweeters, those ones have transformers inside and an awfull plastic bubble that produces more noise than sound.

I think they still construct those things..... 100 watts capabilities and noise producing loud hi frequency drivers (distorters)

We have better factories....Bravox, Selenium, Novik, Arlen have some domination in our speaker market....and many others are dedicated to Mobile Sound Competition, with enormous woffers to thunder sound inside shacking automobiles...those ones the screws goes dancing and parts goes loosing and falling down..hehe.

Here is the link and i will attach the home page image, i think they are preparing the English version....try to translate to English clicking in your flag.

thanks

Spectacular Enzo. I've been looking for some way to bypass buying parts through Fender. Used to be that when SWR was indy they would sell them for about $15.00.

Just about any of the shematics and circuit board layouts would be great for just about any amplifier. I do have a copy of the basic black amp but no board layout and the components aren't numbered. Any help at all would be great.

Silly boy, you think SWR ever drew layouts? Hah!

Fender got what SWR had, which was pretty amateurish documentation mostly. All their power amps were similar. Preamps differed but often had copmmon elements.

Write me direct at:

tmenzo at msn dot com.

I looked on the SWR web site, and all I can find on the SS-180 is a picture and brief description. I don;t see where it says they have the schematic. Where am I missing that?

I have been an SWR authorized repair station since well before the takeover by Fender, and I do not find SS-180 in any of my factory documentation.

What sort of problem are you chasing? And if a powr amp problem, what are your output devices? The circuits tended to be common to multiple models.

I see. Those three little dots make the difference. When searching for SWR SS-180 schematic, or something similar, the search engine looks for those terms on the same page. In this case, the "WorkingPro™ 700, WorkingPro 400, Bass 350™, Basic 350™, Studio 220™ and SS 180™" part was from a paragraph about connecting speakers, while the "A schematic for this purpose may be ordered from SWR by calling 480-596-7195. ...
" part was farther down the page in a section about changing mains voltage.

NOt amm SWR amps were documented, and when Fender bought the company they published what they had.

meanwhile I asked what your repair need might be and what output devices the powr amp used if that was the problem area. We may be able to help.
