Cerebus is on the mark as usual. The PS series I picked because this was a production iron rather than a rework iron. It has three parts: the handpiece, cartridge and tip, each replaceable on the fly. The tips take 5 seconds to swap out. The cartridge 20 seconds and the handpiece about 30 seconds. The whole thing is designed to not cost you time. Also the tips are a lot cheaper
The MX series is completely different.
The T12 has the equivalent of the tip and the cartridge in one unit and the handle separately. It works pretty well but the engineering tolerances of the handles are terrible as are the contact mounts. I was not impressed. For 20% more cost, they could have put together a 100% better iron that would literally shat on the competition on price/performance. But as always they missed the mark in the race to the bottom.
Anyway, on to something cool. 6294A is now fixed. My capacitor arrived so I made a little adapter board for it:
This was then bolted into the chassis in place of the old capacitor with M4 hardware. There are three spacer washers between the board and the main PCB.
Job done, and if an original part comes along it can be substituted in no problems at all.
And it works nicely
