I have a JCM SL-X 2100, one of the earliest ones I think. The power board is SLXa -60-00, and nowhere can I find a print of it. The closest version is 2100-60-02, but it is part of the power supply, even though the print says it is the Power Amp CCT. It is in to check out the Hi/Lo power switch, which has holes drilled in the pcb directly behind the switch. Before I lift the board to investigate, I notice the four 5w screen resistors are 470 ohm, not the 1K I see in other later versions. Should I be concerned with this, as there is evidence of some not to savory work having been done in it in the past.

It's weird, because it WAS working fine..... -
Nevermind, I was looking at the EL34 version. Scrolled farther down to find the 5881 version, and the values match. This amp has 6L6s in it.

Be aware that there are two versions of this amp (other than 50/ 100W).
Output tubes may be 5881 or EL34.
