Got a Sanyo M9820K radio to fix.
The mode switch was not working properly, wiggling the lever sideways sometimes made the radio come on but not always.
I found the switch had intermittent\high resistance contact on one group of contacts. I opened it up, expecting severe buildup of crap. No, in fact, one of the contacts has been burnt away almost completely. I guess it's been switching the main power supply and after 20+ years or so it's died. Fair enough.
It's an ALPS BT566 350F, seems to be 6P3T configuration and which I suspect is highly likely a custom part or at the very least discontinued long ago... (And why the eff do radios always have to have hugely complicated slide switches??
)
Anyway, does anyone have some clever ideas on how I could fix this?
I would steal a contact from the band switch, but it uses all 6 sets of contacts too...
At the moment I'm thinking of just bodging a rotary switch in there somewhere instead, it'll look horrible, but should work...
