Some of the wonderful things about the amateur radio community is that it is seamless, universally friendly, helpful, and well equiped.
There is a HUGE following of vintage tubed gear and the folks with the knowledge and tools to restore gear are EVERYWHERE, willing to help with access to a vintage tube tester (no longer found in every drugstore) and autotransformers. And scopes and signal generators for that matter.
Find your local amateur radio club, attend a meeting, request help on a tubed project and it will be answered.
@R Sweeney - Excellent advice, and when I said it probably still works I should have added the caveat about the electrolytics. Written in haste.....
Very few people have a variac or a tube tester to hand. A test of the disconnected electrolytics with a lab PSU at maybe 50V is a good start. If you're in the US you could then use an isolation transformer (a must) and a rectifier with a beefy 10K resistor in series to put about 160V on them, Leave it on for a bit , monitoring the current (should go quickly to a few mA or less), to let them reform. But caps of that age will usually be dry (= low cap) if nothing else.
If you can just replace the electrolytics (which is probably the best way to go) then you'd probably be fairly safe in trying a switch on, with a meter across the main electrolytics - if the voltage does not go up to a few hundred volts right away then switch off and dig further.
As a rebuilder of old tubed Heathkit ham gear, you NEVER just turn on the power and see what happens.
The 60 yr old paper caps on these pieces are almost 100% quaranteed bad, open or shorted. And those bad caps can damage irreplaceable components on failure, like hard to find transformers. And a surprising number of carbon resistors crack with age.
Step 0: get and read the manuals
step 1: replace the paper caps with modern high quality (non-Chinese) electrolytics
step 2: clean all the switches, pots, sockets
step 3: test the tubes
step 4: use a variac to SLOWLY bring up the line voltage to avoid in-rush issues with components which have not seen a magnetic or electric field for half a century.
step 5: if it works, rejoice, if not troubleshoot and find the dead guy(s).
step 6: Enjoy the rebirth of someone's old friend.
@Caleb: The surprising thing to me was when you took the cover off -- seeing how few components were used -- I was expecting it to be jam-packed with circuit boards and transistors -- I hadn;t realized it was vacuum-tube-based.
I am also circa late 50's and used this scope when I was a kid. For the younger crowd, an interesting aspect is the long neck of the CRT which is because scopes used electrostatic deflection rather than electromagnetic deflection. Faster, but a narrower deflection angle.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
