Waste-not wednesday
There, rhyming problem solved.
Now, on to other info. This looks like a Matsushita design. The slide potmeters are standard parts from panasonic ( matsushita subsidiary ). The single in line package is common for this kind of device. It is the preamp that hooks up to the tape players head.
In the late 80's early 90 i did a lot of repair on car radio's. These sil packages were everywhere. Tape preamp , stereo decoder, equalizers , line inputs for pow amps.
That lcd driver is sanyo,
There is something special about the pcb as well. Even though this is a double sided board it most likely is NOT plated through. Plating on phenolic resin boards ( this is not a fiberglass board ) doesnt work very well.
They squirt an epoxy based compound that is electrically comductive in the holes , let it sit for a few seconds and vacuum pull it back out. The compound is then UV cured. Sometimes this compound is blue and easily recognizable . Here it looks like they used the clear or light green variant.
That is why you have the sheen on the board. Besides the soldermask there is an additional coating to protect the vias.
These boards are not drilled. They use a punch and die press that punches all holes in one operation. If you look around that single in line package or the regulators you will see that there is no copper on the top layer and no metallisation in the hole.
Board is etched, soldermask applied , punched for vias , paste squirted and cured , punched again for thru hole. Sprayed with additional coat to protect vias. You cant solder on these vias . Solder does not stick to them and you would eventually burn them out as well.
