HP 6038A System Power Supply: all fixed!

After some weeks, the spare parts arrived – RIFA X2/Y2 rated capacitors (now made by Kemet), a full set (see earlier post, 6038a repair).

The new X2 capacitor, let’s hope RIFA has improved the resin and durability. Albeit, the old capacitors lasted for a long time…

And a fan, from China. The fan, upon close inspection, it has a broken frame, but fair enough, I will use this one while a replacement is on the way.

A lot of dust removed from the case and boards, all completely disassembled. The X and Y capacitors all replaced – the old capacitors are still working, but cracked and it is good practice to replace them, unless, you want to risk a lot of smoke and stench (usually, at least no fire risk).

Always good to use high quality tools – I only have low quality tools here, and bits that crack!

All cleaned and put together…

…finally, some testing. It is working, the fan is providing a substantial amount of cooling, it is definitely big enough for the unit.
