Title: Replacement / alternative for contrast switch Hantarex MTC9000
Post by: sollima on January 22, 2020, 02:25:01 pm

I always have a reddisch glow when adjusting the colors. Lowering the Gain and Cut-off to the max still gives too much red in comparison to blue and green.
I replaced all the potmeters and transistors on the neck-card and the diodes and transistors on the mainboard of the red-circuit.

When adjusting the contrast switches I noticed when I turn the switches the other colors become brighter and dimmer except red.

I concluded that the red switch has gone bad.

I have trouble finding replacement switches. Can someone tell me what kind of switch it is? Or where I can order one?

Thank you in advance.
