Hello
,
You might want to take a look at this -->
ftp://bama.sbc.edu/downloads/radiocit/rc314/ It's the user manual for RC314 tube tester. I think it's pretty much the same as your RC315.
I would also recommend anyone who has an interest in old equipments (i.e. oscillocope, counters, testers, etc.) to check this website out -->
http://bama.sbc.edu BAMA (Boat Anchor Manual Archive) is a great site. FULL of information. They also have schematic diagrams for tube Heathkit, EICO, TELEFUKEN, etc.
In the U.S. these old equipment are called Boat Anchor because they weigh a ton!! You can them for next to nothing.
I bought an older analog Textronix oscilloscope, HP frequency counter, EICO capcitor tester, etc. for peanuts.
My Textronix oscope was a military model and it's built
a tank.
Hope this helps!
Best,
ABMOGGY
