7904A channel switch/A5 PCB/junker? (USA/EU)

[jonpaul]

 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
