Hello good people , please i need your help , i have a transformer that i took off from an old stereo system that has been in my basement , the transformer still works good , i know because i supplied the input and it was vibrating , but the output terminals are kind of messed up , i wish to know if any one here can determine the properties of the transformer , pictures have been uploaded

 

I don't know about anybody else, but I can't find any data on that transformer. But I will tell you this: If you want to use that transformer to power your bass amp - that one is WAY WAY too small. Even if it has the right voltage.

Also; assuming you have a transformer capable of supplying the voltage and current your amp needs - you're going to have to build a rectifier/filter circuit for it. Otherwise simply rectifying the output will result in absolutely horrible sound.

I realize you're trying your best to get something going that will run your amp. As in the other thread, recommendations are you buy the appropriate power supply for it. Right now it seems to me like you're groping for a solution that doesn't require much thought. And your project is going to require a little more thought than you've put in so far.

 

Let's stick to one thread since it is on the same topic.

 

Thread unlocked as TS claims transformer is for a disco lighting.

 

Yes i took out the transform from an old stereo start from my basement , i just wish to know if any one here can get the properties of this transformer , before i can start doing research on the type of disco lighting i will like to building , am home all day , don't want to spend my time doing nothing when i have good people like you online to help me.

 

Going by the apparent physical dimensions that would typically be a 20va capacity.

You could get some idea by knowing a little more about the amplifier it came from, I assume it was solid state and not a valve amp? What was the output power rating of it? This basic info would be a guide as to it's power rating, but as max said, it looks fairly low power.
When you say it is vibrating, is it getting hot with no load connected to the secondary? If so, it may well have shorted turns, or you are putting power into the wrong winding.
Do you have an AC voltmeter and some sort of load you can connect? Once you know the off load voltage, if it is not too high, you may be able to use some car bulbs (in series if necessary) and get a better idea of what it is capable of.

 

Your middle picture seems to show 5 connections on the secondary winding side. Give each connection a label. (A number or letter for example.) And sow on a picture how you have numbered them. With no power connected to the primary winding use your multimeter set to a low ohms range to measure the resistance between every pair of connections. For example if you have given them numbers 1 to 5 the measure 1 to 2. 1 to 3, 1 to 4, 1 to 5, 2 to 3, 2 to 4, 2 to 5, 3 to 4 and so on until you have measured all combinations. Then post the results. I expect all of the readings to be only a few ohms. (Unless the stereo system used valves.) From the results we will suggest the next step.

Thanks so much for the heads up , i will buy a new AC voltmeter this morning and see what i can do
