Hi guys
I found an old smps in a blaupunkt car amplifier with output voltage +27 0 -27 Volts.
I would like to tweak to have a better power supply:
I already change the old capacitors at primary and secondary:
was: 4x 470uf for primary
now: 4x 1000uf
was: 2x3300uf for secondary
now: 2x10000uf
I also change the two rectifier diodes by 1 C2522 and 1 C2526 support more output current:
But i would like to change the four mos-fet Buz103Al with four IRFZ46N because the ouput current is better for the IRFZ46N mosfet
Do you think it's a good idea?
But before any change on the power supply i found a resistor very hot i don't know why it's strange
This is a photos of my power supply with resistor who are hot.
Is it a resistor to compensate the temperature?
ps: for you américan do you think my english is very bad or it's ok
Sorry for this stupid question
Thanks for your help

An externally hosted image should be here but it was not working when we last tested it.
