Anyone does it, I have the schematics but there are quite a number of components to add?
And the power transformer seems to be the killer

Re: Converting RX-V373 110v to 220V
Unless the primary side of the transformer has dual windings, then there is not much you can do.Never stop learning

Get a seperate step down transformer with the proper wattage and just use that.Attached FilesComment

Hi all,
I recently picked up this amp as not working. I took it as is. Didn't notice until I got home it had foreign power plug and was marked 110v and our local voltage is 220v so then I knew what had happened to it.
Opened it up and was able to find the schematic online. In the schematic I have uploaded I have erased the parts for 220v operation to make it easier for me to visualise however I have since added the two additional diodes and remove the wire link from the power supply so I can test it easier on 220v
From the FAQ I learnt that for 110v the power... -
I need help to ascertain if the power supply on my Yamaha SY85 keyboard is 110v or 220v or both.
I have attached the schematics below.... -
I need an AC transformer because the one I used is burned. Since I have some unused DC transformers, I wonder if it is possible to just remove the bridge rectifier from it to convert it to an AC transformer. I measured voltage before the rectifier on this one - it shows 13 VAC, and 16 VDC at connector without load. Rated 12VDC 1000mA.... -
Hello!
I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.
Measured voltages with no load:
After rectifier diodes
12V: 6.17 V
5V: 5.67 V
Secondary transformer pins AC measurement (really don't know if this says anything)
12V: 2-2.5 V
5V: 1.04 V
I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,... -
Hi all,
Got this local made DC power supply (12/14V) given free as the transformer has melted. There is no marking or indication to identify what type or rating of transformer used.
Fyi,. I had a busted autogate mainboard with transformer with marking 13-0-13 . Is this the 13v dc type transformer?
My questions are
1. How do i test to see if the transformer is in good working condition?
2. Can this transformer (marking 13-0-13) be used to replace the melted transformer on the DC power supply?
Hope you guys understand what i was asking. My intention is...
