Update in the Philips 22AH105 tuner.
I hooked it up to the aux of my 22AH708 receiver again to let it play for a few days to see if there still are, or other (new) problems.
FM reception performed intermittent. Like disappearing cut out left or right channel or signal at all. On FM only that was.
But that turned out to be easy fix. Bad solder most foremost. And now it is reliable so it looks like at least

Reception and sound quality are top notch by the way.
I did also some troubleshooting regarding the lights. But is indeed just burned out bulbs. I do have them. But that's work for another day.
All LEDs are working, despite the seller stating in the listing, most LEDs were out.
Preset memory 100% working digital digits bright as should. Seller stated they were dim!
Removed some flux residue still on the circuit board from earlier repairs / replaced IC's. And I did some fresh solder reflowing here and there.
Controls are still a little scratchy. I haven't tried to spray them or remove and clean them yet. Also that is for another day.
For cosmetics; I did clean the inside and outside of the chassis and wood cover, but not the faceplate, knobs and glass yet.
But the tuner looks already a lot better.
The tuner is 'singing' like a dream for more than 9 hours now. Hence 'fingers crossed'!
