Clean the jacks and especially the cutout contacts in them.

Hi all first post for me  :tu:

I bought what i thought was a dud sessionette 75 mk1 2 years ago ,

I did look around at the time and saw it could be a number of things (not loud hum but no output) and put it away as it was going to be a donor

But yesterday i looked at it again and got the mmeter out and checked for dc at the speaker and averaging 16mv

Put a lead in the extention speaker socket to see if any different reading and same ,

When i pulled the lead out of socket the amp crackled into life  :dbtu:

Did it once again but no after about 8-10 hours use it seems fine ,

Sounds awesome too , i have a rockette 30 but this is way better ,

If it happens again anyone have any ideas , Im pretty good with my hands :duh

thanks all

Nope.
Pretty rare pedal.
They only made about 100 or so.

Hi..New here...Looking for a schematic or pic showing how the transformer on a Kustom Duel 30RC amp plugs into the circuit board.  Picked it up at the goodwill and someone had pulled the wiring from the transformer to the board off... Any help would be great.....Thanks

The more someone tells me don't do that, the more I want to try. Or at least experiment to find out they are right ;-) So disappointed  :o

No, but seriously, thanks!! for the insight, the more I look at that your answer, the more I see it replies to my original question. If I do some experiments sometimes later, I will share here.

Cheers

Yes... Well, I learned today that the g1xon has different level controls, one of them, the master level can make a difference. I will keep trying. Maybe I can use my nice diy amp after all...

Pin 1 & 8 of the LM386 set the gain.
You are supposed to use an e cap (10uf) for more gain.
Not a jumper wire.
No cap and the gain is set to 20.
