RE: Disassembly of HP-19C
Hello,
Now the bath is over, and I think this is as far as I will come - please let me know if you think otherwise. I have checked the printhead resistance and it is about 14 ohms for every printhead resistor, so I think it is OK. The plan is to check the transistors for short-circuit and the traces for discontinuity and then re-solder the PCB where needed. Thanks to PANAMATIK, useful tips have been provided for substitute components if needed.
Best regards Jonas
