Audio Analogue Puccini - help with input selector fix

[ukmart]

Hi guys,

Recently I came across this Audio Analogue Puccini Special Edition amplifier

It's generally in working condition, unfortunately its input selection knob was very loose. Upon inspection I found small PCB rotating and hitting resistors when using that input knob, which didn't seem right to me.

I'd like to fix that, and make it work as it was intended to. Does anybody have pictures of properly working input selector, or any advice on how to fix that.

It looks to me as an lineair potmeter ('102' -> 1.0kΩ?) generating specific voltage levels decoded into the various input chanels by mux's somewhere else. Better pictures of the 'green thing' can help!

Now it is broken and you need a new one - no chance to get the axis in firmly again ..

Seems it's an Alps Alpine make potentiometer.

Do you think this one will do (only horizontal type available):

It is an Alps (or a rip off), 102 suggests 1kΩ (not 10kΩ or you can select only one source). Measure the value of the pot 2bs, and give it a try.
