Technics SU-V75 amp power button issues

Hello everyone. I love my Technics SU-V75 amp. However, I have an issue with the power button. It clicks into place, but power will not stay on unless physically held in place. Perhaps the spring has been pushed/bent too many times?

I haven't been able to find too much information about this equipment. Has anybody had this problem before? I thought to just replace the power button... but I haven't been able to find the right replacement part as I don't have the repair manual. Anybody know the correct power button replacement part or where I might find this part?

Someone else may chime in with a correct replacement but I have had that issue in the past and my simple solution was to tie the power switch leads together and just use a power strip as my on/off.

I have the same Techics SU-V75 amp with a bad power switch. Can you explain how to tie the power switch leads together? I see a brown and grey wire coming from the back of the unit (by the power cord receptacle) then a black wire from the small cirquit board leading to a metal box like contraption. Which wires do I connect? I am a carpenter and see no wood inside this thing even though for a while I had a small piece of oak forcing the connection in the switch. This is not working anymore! Thanks for any help as I do not want to lose this amp and have to buy a new one.

They actually stock the proper Matsushita power button. It is an easy fix to desolder the old one and put in the new one. About five minutes of work for happiness. I actually replaced one on my SU-V75.

Those old switches are known to fail and if you take them apart they will just fly apart. There isn't much in there to fix. It's like a mini seesaw.

If you call them tell them, that someone on Audio Karma bought a couple of them at their store and that they are in a small cardboard box at the bottom of a shelf.
