so i came across a guy selling a working pro 10 for 50 bucks with a 210 cab.

but heres the deal he said he had to get it tested by some people and they needed to un solder a few wieres from the looks of it look like the speakers and tweeters need to be hooked up but just in case heres the link:
Link Removed

so if anyone knows if this would be an easy fix let me know, but hey its 50 bucks for the whole thing, plus maybe 100 bucks max an id have a better amp than I do now.

BTW it would be great if you guys could respond soon because i want to pick this thing up by tonight or maybe tomorrow...(itll help me study harder for exams :D) Thanks in advance.

yeah thats what the guy said,

Madison 16ohms... is madison a respected company for drivers?

is 16 ohms good?
will this work?
would it even be possible for me to hook the 2 10's to the unit?
so many questions so little time. :P

Hi.

If You want to use the speakers with any SS amps, that SWR included, You should wire them parallel to 8 Ohm load. Wiring the speakers to the amp can be done with a normal "lamp cord" as it's heavier gauge than some of the so called speaker cables anyway.

The "cab" seems a bit light constructionwise so You should consider building a new enclosure and perhaps make a separate box for the amp as well. That way You can use the amp as a head with different cabs if the Madison one isn't satisfactory.

I have no idea about the Madison speakers, but the price for the package seems low enough to me, I'd grab it.

Regards
Sam

Madisson speakers are not that good but were talking 50 dollars worth of speakers.

Good quality 10" drivers will be around 80$ a piece. thats what it costs me for replacing a driver in my Trace E cab. that was 15 years ago

Maybee something can be done with the amp unless its been beaten to death.

I would take my chances just to play around with it.

thanks for the responses.

So what i could do is take the power cord of a lamp and use that?
and parallel means a wire going from each driver to the "head" correct?

since both the speakers are 16 ohms i can use them...but when i went on the swr site i found the manual. it says.
MINIMUM IMPEDANCE: 4Ω for the power amp

so does this mean that i could change/use a cab with a 4ohmdriver/ 2 8ohms?

also to fool around with this could i just use tape to temporarily hook the wires up or would i need to solder them in place? Thanks a lot for the help.

Yes, parallel means + from input jack to + on each driver, - from input jack to - on each driver. Cheap speaker cable from Radio Shack is fine. Lamp cord is probably fine as well. Probably don't want to go smaller than 14 gauge.

This means you do not want to go below 4 ohms. Running at 8 will be fine.

You could use a 4 ohm cab. You could also use 2 cabs at 8 ohms each.

Just make sure you have good contact and that the wires are secure. I'd solder things up eventually. You in general really want to avoid a short across the power amp, but with a modern SS amp it will most likely just politely shut itself off.

ahh alright sounds fun.so now would this sound good? haha once its all done? ive seen the workingpro110 go for 400 - 450.

also this guy just sent me a few pictures there one where it shows wires, 2 pairs of wires they look like they can be hooked up to speakers. but lets say their not how would i hook up 2 drivers to the "head"

Banana plugs are just a system that fulfilled the same sort of role that people use speakon for these days. You see them on older pro audio equipment. I just think those speakon plugs feel flimsy, plus I've been making up banana plugs for years. You can also daisy chain them together, which can be handy sometimes.

No i think they are bass drivers [Invalid or Expired Link Removed] just pretty old ones.
but for 50 bucks if the electronics do work i got a good deal i think, i mean anything is better than what im using know, my headphones are better than what im using now. and i've got 10 dollar sennheisers.

now the problem is picking it up, i dont drive, my pops wont take me. he lives 1 hr bus ride away, the "cab" is 55 pounds. but you know what im thinking i shuould its gonna be a good experience.

OH and what parts am i not allowed to touch ive heard that if i touch em i could die?

If you don't know what you are doing I wouldn't be poking around in the amplifier at all. Their is nothing in a speaker cab that can hurt you.
