D'lite rocker switch safe rating question

Hi,
I want to use this toggle for turning a D'lite 22's clean/od mode. My question is, Is current rating of 2A, 5A ; power rating of 400mv safe for this function?

Thank you.

Re: 290BX PT - d'lite 22 6V6 powering up issue

thank you for confirming. one more question about the volume pot wiper and right side lug being connected in the layout.
is this correct? please look at the screenshot. I don't have them connected at this time.

Re: 290BX PT - d'lite 22 6V6 powering up issue

bump...
i connected the left 5uf/resistor to ground. amp is making very low output at full volume. almost no tone change when eqing.
should I ground the right 5uf/resistor to ground as well? I reconnected the relay board back in. any suggestion other than audio probing ?

thanks

Re: 290BX PT - d'lite 22 6V6 powering up issue

I spotted few errors in the layout. Please confirm. 5uf coupling caps with the resistors are not grounded. Am i correct? I know for sure the left coupling needs grounding. What about the right one, (coupled with 10m resistor ) that connects to the relay. Should i ground this one as well. Please conf...

Re: 290BX PT - d'lite 22 6V6 powering up issue

i took out the relay board power supply and the relay board. not considering the footswitch for now. I am following this layout attached. the green arrow marked 3pdt switch. what is it's function?

i want to use the OD channel only without the need of the switch. how should I wire it ?

Re: 290BX PT - d'lite 22 6V6 powering up issue

pilot light has been fixed. i removed both the 1M resistors. so the capacitor doesn't need to grounded? I have it grounded.

Re: 290BX PT - d'lite 22 6V6 powering up issue

yes, i am also guessing a wiring issue. looking at the layout, the rectifier board (the small one on the left side of the chassis), the large capacitor's positive side is not connected or grounded.

Re: 290BX PT - d'lite 22 6V6 powering up issue

it looks to me the pilot light is blown. all the tubes are powering up okay.
I can see 120V on both sides of the power switch. and the rectifier diodes has 350V AC
6v6 power tubes has 488 on each.
but i get no sound when i plug in the guitar.

is the OT at fault?

please advise.

Re: 290BX PT - d'lite 22 6V6 powering up issue

I connected the 5v yellow wires to diode and capacitor for the relay power. two boards are stacked and not showing in the pic.

please take a look at the layout attached. two black arrows are pointing to the wires coming out of the PT. are these the same as the 0v and 120v in 290BX PT? please confirm.

Re: Brown note D’lite 22 half power switch

Hello, the half power switch for 6v6 amp will not benefit tone wise. I have tried with 50 watt amp and it did reduce the power substantially. but for 22 watt i would try a attenuator instead. i have a question about the layout. what is the right most part that connects 3 wire in it. the bottom left ...
