Where can you find suitable powersupply for that? It would be intresting to know the voltage on the PSU...
@NeerajGulati
@NeerajGulati Год назад
I had bought it from a shop in the electronic market of Delhi called Lajpat Rai Market in Chandni chowk. Don't remember the exact specs but we had matched the output voltage of the previous supply just changed the input voltage from 110v to 220v.

Why do you need to change it from 110 to 220 when you can use a step down transformer?
@NeerajGulati
@NeerajGulati Год назад
Good question. I was using a step down transformer but it has 2 challenges. One need to turn it on and off everytime after use and two it has a hissing sound.. quite low but its there when the subwoofer is ON

My vintage yamaha sub that I got from my brother is taking time to power up.. could be the servo? or the power supply (transformer)?

Mostly likely the power supply capacitors are not good. Have them replaced.

@@wongalex7123 Most likely the 2 big capacitors need to be replaced. You could see the value on it. As long as the stated value is the same as the new ones, then no problem. Eg. 4700uf, 25V. Can go higher but not lower.

What is the rating for the transformer? I have the similar subwoofer SW012 8" inch (US- using in India) and don't know what rating transformer I need. 12-0-12 or 15-0-15?

@NeerajGulati
@NeerajGulati 2 года назад
You will need a step down transformer that will convert the 230V to 110v. Do not plug it directly into 230V

I got this one sometime back, I guess around 2013 and got it in flight as checked in baggage. They let you take it what you might want to check is the custom policy at the destination country.

@@durbandadagaming7774 usually size is an issue at check in stage. If you have baggage limit it shouldn't be a problem. For details you can check with the airlines helpline. The bigger cost inflator would be the customs at destination airport. They have a certain amount for electronics which is exempted after which electronics attracts quite a heavy duty. So you would want to do that cost benifita analysis before.

@NeerajGulati
@NeerajGulati 3 года назад
Check 3.29 there is a transformer with a code X8.. That is the step down transformer with 110v input and we need to change it to 220v input. Update: Couldn't find the 220V supply so have to live with the step down for now.

Just use a power transformer to step down. I have not seen your followup vid so I guess you've given up.
