18w tmb plexi

[Davidbob]

Just finish my build. Hope to take some time to start it tomorrow.
But not sure to keep the cascade switch. I think to remove it and install a 4 input that i' could jump, like in a real plexi.

Start it today.
Lot of squeal when i cascade chanel and raise volume. Little disapointed.
He do the same thing as the mojotone 18w tmb i build Last summer.

I don't really see any use of shielded wires. Can you confirm that you did and where? Maybe post your schematic and note the wires that are shielded.

Wire from input thrue tube socket are shield.
Anywais, i have remove the cascade circuit and modify it with 4 inputs like a real plexi.
Now, all is good, sound good.
