Early 400

[wattsabundant]

Anybody seen this? I don't think I've seen this bus wire for the ground nor the soldered connections on the caps.

No Don, never saw that...

I have seen a couple of pics from time to time on the net that show a solid coper wire with soldered lugs terminating at the caps....
But never seen solder terminals on the caps ....

I had a PL400 like that Don with Lelon caps installed and a bus wire soldered between the cap terminals, just as your picture shows. I still have those caps sitting on my antique shelf. I have also seen ones with bus wire and a #10 ring terminal soldered to each end of the bus wire, used with screw terminal caps.

Those connection types obviously no longer exist in my amps. These were mods done by prior owners, not stock.

I've got a 700B with what looks like #10 solid copper and solder lugs for the ground bus. The photo I posted was sent to me and the wiring looks like a factory job. Doesn't matter as it will go away.
