Hello all: My 7904A has a broken channel switch left/ALT/ADD/CHOP/RIGHT
on the A5 mode switch board
It is a Five position push button, TEK manufacture, uses PCB as switch contqwcts. Has broken mech/ detenting and loss of left channel .
Looking for the following TEK parts
vertical channel switch PCB assembly A5
OR
Five position S325 Mode switch
I am hoping someone on the forum has a parts donor or possibly original TEK spares
(Please note the channel switch is completely different from the 7904)
It's possible 7104 has the same switch
Can swap or arrange shipping, either EU (Paris) and USA.
Have a great day,
Jon
