Dear forum’s members and lurkers,
I’m glad to assist to anyone, who address personally to me, if I have the right information.
This applies both to the schematics that I uploaded earlier (and which are now inaccessible)
and to the new requests. I apologize that I cannot give detailed explanations step by step.
I just don’t have enough time.
Please specify manufacturer and model. Do not forget to send your private email address,
which I will use, if the volume of the information exceeds attachment limitations of this forum.
I beg to inform me about measurement equipment, which you have/use. This will help me
to understand with who I am dealing and to formulate an answer in optimal way.
Measurement equipment, which you have/use.
Please choose:
1. I do not have/use any measurement equipment.
2. Continuity tester.
3. Multimeter.
4. Analog scope.
5. Digital scope.
6. Logic analyzer.
If you want, estimate and provide your knowledge in electronics and/or professional skills.
Knowledge in electronics.
Please choose:
1. I know nothing about electronics.
2. I’m familiar with Ohm’s law and I can read and understand electric schematics.
3. I’m familiar with discrete and linear devices (transistors, tubes, opamps, regulators, etc.) and
I’m able to work with their datasheets.
4. I’m familiar with digital devices (logics, controllers, memories, ADC/DAC, etc.) and I’m able
to work with their datasheets.
5. I’m a B.Sc. in Electronics.
6. I’m a M.Sc. in Electronics.
Professional skills.
I can successfully replace:
1. #4-40 (or M3) screw Phillips pan head.
2. EL34 tube.
3. Axial lead 1W resistor.
4. Radial lead electrolytic capacitor.
5. SMD LED of the 0402 footprint.
6. 208-pin chip of the TQFP package.
Doctor.
