I had to power down the TR4X+B today (First time since July 2021)

short story the caps have finally got to the point that i cant hack it to power on

 

2 Caps are bulging

 

They are

2200uf 10v

LE105°C 2103 (M)

 

Does anyone know if there is anything special about these or can i just replace them with these?

I have the 2200uf 10v caps on order

and a Noctua NF-R8 redux-1800 Fan

 

The old 2200uf 10v caps are 30mm tall by about 7mm wide

The replacement caps are 25mm tall by 10mm wide so its going to complicate the swap

 

Will post an update in a few days on if i manage to bring it back to life without a new psu

Hi Shonk:

 

Power supply replacement wasn't too expensive back in 2018. I purchased one for $59.00 plus shipping. I got it as a spare after reading the stories of power supply failures being the major issue with the TR4X series. I live in Australia though so wanted to be prepared in case, but never had to use it.

Don't mount the new ones flush on the PCB. Leave about 5mm or more of "legs" so you can bend either caps more or less out of the way.
