Hi all, the clipperton l I picked up appears to have had the relay rigged, probably for cb use Angry
When you move the standby switch to transmit, it keys the relay. So they weren't using a cable from a transmitter to key the amp.
It looks like someone moved the yellow wire that comes from the relay. I am wondering if someone would have a link to a wire diagram. The schematic I found on-line, doesn't color code wires, and isn't helping me. Maybe someone would have a couple pics of the standby/transmit switch wiring? Any advice or ideas would be greatly appreciated !  Thanks, Chris...

If you have a schematic of the amp then just wire the switch and relay as shown.  Simple job.

Host it elsewhere and use this generic code -

Repairs using a color wire approach -- is inherently dangerous with HV and HF vacuum tube amplifiers.  
You need to ADVANCE your schematic reading / comprehension skills.

NOTE: The former owner MAY have also defeated the HV interlock -- dangerous modification.

Here's the schematic, albeit a little large

You are 100 percent correct I do need to advance my schematic reading skills. The HV interlock switch works and isn't bypassed

OK, thanks for posting the schematic, that is the one I have also. Keep in mind all, I am trying to learn. I am used to color code schematics used on ATVs and RVs so this is not easy for me.

Looks like yellow wire to relay goes to one side of standby switch. Anyone have the cover off of a clipperton l ? Are there 2 wires on each side of standby switch ?? , Thanks

YES, that level of instruction is designed for NON-Technical Consumers.
Citizens Band and Family Radio are also for the Non-technical USA consumer (leave no child behind).

Amateur Radio is Technical, per FCC Part 97 (First paragraph) since 1920s,
SO the documentation is written for that level (this won't change).

I had several L's over the years... not a bad amp but really "clunkey" if you know what I mean. I finally ended up with an alpha 87a and will keep it for ever,  great amp.
