What are theses pcb leds for?

[frank57]

I have this Hiwatt solidstate the Bulldog 30r.
it was working fine for quite awhile.

It sounds like the volume is a bit low on the clean channel.
Are the pcb Leds2 and 3 to indicate which channel is on?
At the moment I don't see either led on.

i drew up the board before but I also have attached the schematic.
It's had some issues in the past this amp with volume levels not staying consistent.
Other thing was: how would I wire the jack if I wanted it off the pcb?
the input jack section was cut by a tech to stop a radioo problem.I didn't indicate it
