Question about Samsung OKIDATA - OKI Microline 590 Printer
I have several Microline 590 Printers and each one has a bad power supply caused by a spike. It appears that the parts that are bad are on the vert. board. Board location PC101 & PC 102, Is there a dealler that I can get these parts from.
Oki printers are about bullet-proof and I once maintained them.
I'm not sure that your failures were all caused by spikes unless they were all plugged in during a surge.
These aren't new anymore and their failures may be related to electrolytic capacitors simply having decayed.
Already some years ago, I found several instances of this.
The meter I used (and still do now and then) was made by an insturment manufacturer named Tenma and has been very useful over many years although the price has gone up some since I bought mine, the $209 is still not bad for its capabilities and the dual display saves time if one needs to measure DF and this is critical in your case.
I see you are in the electronic service business so you may already have one available.
If not, take a look at this one:
