#meanwell — Public Fediverse posts

Here a comparison of the old #powersupply and the replacement.
I already cleaned the old board, removed two rusted diodes, and unsoldered the ICs, but there might be more defective components, that's why I decided to replace it with something completely different.
Still unsure if I'll leave the cable binders for keeping it in place.

After getting the #Commodore #C64 and #C128 running again, the next device to repair is the #C1571.
It had #corrosion and #rust on the main board and the power supply is beyond repairworthiness. I'd replace the latter with a #meanwell RD-35 with 5 and 12 volt output.
One #diode was rusty, a few traces needed #cleaning and five #resistor looked bad. Hope the black hybrid chip is still okay.
Sadly, the lower read head seems to be broken, my work might've been in vain.

I attend the local #repaircafe to fix #electronic stuff for some time now. Until now, I brought a big pile of boxes with a collection of test equipment I took from my #lab. But: it takes time to set up the desk, the stuff is heavy and bulky, there is limited space and it always ends in a mess of wires and tools. So I got a nice alumnium suitcase used by #Siemens #servicetechniker back in 1997, some #MeanWell power supplies (48V and 24v and 12V), a mains power meter, a DJ gooseneck LED light, a #dps5005 , an electronic load module, a USB C PD and USB A QC truck outlet (24V) with power measurement and a mains outlet. And a circuit breaker. So basically the suitcase will house all power supply and measurements needs, a TS100 soldering iron, portable scope, Multimeter, mini Laptop, quicktest, ESD mat, ... I hope this will make the whole experience less messy and way simpler.

The attached pic shows all the electrical stuff in a "dry test".
