Using these methods you can avoid a lot of willy-nilly guessing.

Make yourself a check list to keep your troubleshooting in order.

1a. Get the schematic.

1b. Set up your test equipment and tools

1c. You have made a visual check for damaged and destroyed components.

2. Check all wires and connections for broken or cold solder joints.
and Trace out each wire for proper connections.

4. Make a list of the tube numbers on your check list in a descending column with spaces for listing pin numbers, Also mark those tube numbers on the chassis next to each tube socket.

5. Then post the measured voltages of tube pin numbers and

6. Check the voltages of other parts.

7. test the tubes You have already have

8. Troubleshoot by stage, using process of elimination.

9. Record each step so you know where you left off.

10. Once you get things operating then you can focus on doing the alignment.

You can bypass some steps as you get aquanted with troubleshooting and it becomes natural.
Also make a list of test equipment and the manuals for them (A lot of those can be found on the internet).
make a list of to do projects
make a list of supplies you need
make a list of parts suppliers
Keep this list in a composition bound book.
i have learned to also put formulas in a book and on my computer.
Have a scientific calculator at hand at all times. (I have several HP ones) and even 3 sliderules Like a Star @ heaven

I'm a Science Thinker, Radio Tinkerer, and all around good guy. Just ask Me!
