Anyone with experience of the original "orange tube" C8s?
I'm now the proud owner of one, about 70s vintage. Don't know how long since the RA motors have been used.
The socket is something I haven't seen before, but it has a plate saying 220V 50Hz - so it looked promising (hopefully designed for Australian and hopefully southern hemisphere rotation).
With no other information, I pulled the base apart and decided to replace the unknown socket with a suitable 240V plug.
Before that I ran a meter over the wiring to look for any shorts - active to neutral or either to earth. None - looking good. The two motors are wired in parallel to the power supply.
So I wired up the new plug, hoping active/neutral orientation wasn't important - I wouldn't expect it to be. Then I ran a little WD40 down the shaft of each motor below the cog.
Then powered on with the base disassembled. I could certainly hear one motor if I got my ear up close. I'm sure I could hear the other motor as well. No smoke, no funny sounds - good!
Reassembled the base, engaged the RA clamp and plugged in the power. OK, up close I can hear at least one motor ticking away. BUT - no rotation visible on the RA scale.
Gave up at that stage?
Any ideas what could be happening here? Have I just not done something correctly? I have found a copy of the original manual from the internet and read that carefully. I seem to have done everything correctly.
BTW, the RA clamp and RA adjustment knob seem to be functioning well.
Anyway, I'll get ahead with building my wedge. Even if I cannot get the drive working, that will make observing easier.
Thanks in advance
Eric
