I need to replace the Hi-Off-Lo standby switch on my RP65. The switch lever has a soldered cap with a spring inside, the cap popped off and the spring is loose. I have tried putting the spring back in and holding on the cap but the switch doesn't work.
I've bought a new simple on-off-on switch but not sure this will do the job.
The old switch was soldered in with a brown wire to the bottom lug, white wire to the middle and red wire (+resistor link to lamp) to the top lug. I've tried wiring up the new switch with the wires to the same lugs but it's not working. In the Up position the lamp lights up but just get a faint distorted sound, nothing in other two positions.
Does anyone know the significance of the spring and cap on the switch lever? Is it somehow involved in reducing the power perhaps?
I can research the wiring and make a better diagnosis of which lugs to use on the new switch, but I'm thinking I need something better than a simple on-off-on switch.
Photos attached if you can help please.
Update Sep 2. I have checked the schematic and the wires are as expected, brown to high power and red to low power. So either the spring in the old switch was doing something clever that I can't fathom, or whatever caused the switch to break has taken out another component. I would appreciate any help you can offer; I re-capped the amp a couple of years ago and it sounded really sweet up until the switch broke. Thanks
