I find may designs using externally fed by discrete oscillators. Mostly, they are not depending on internal transistor for LO. Perhaps it helps resolve this issue and also internal interference due to oscillation .

Appears your concept of thick to thin could work
see example images
while we make the board, we can call for needed packages and change the internal pads therein, by using drill and diameter .
save and come out
on the board layout we can call library and "save all" it would bring the changes on to your component modified.
there are no errors after pressing...
as per datasheet following programming of B port helps

i have been buying on ebay for last 4 years.
Yes, I had some failures.
But major things are ok.
however there are many versions of LM386 with gain variations, I suppose..
please see the datasheet.
After all ebay is a consortium of sellers. Only issue i had with ebay or any other on line...
Thanks for fast reply Brian,
I am attaching photos of the device for ease of identification.

I have a chance to get few LCD glass displays branded SGM2175 Ver1.0
i failed to get any data on this device
it has 22(11+11) pin lcd glass with edge pins soldered to board
the board has 9 pin connector facility
it has One CoB behind.
and back lit for lcd
i could assume two pins for...
Re: [Moved]Programmed microcontrollers
most of proprietary chips would be code locked.
I dont expect that you could copy and reprogram.
P{erhaps the only way is to correspond to company who supplied the equipment, pay and get a pre programmed chip claiming serial # of faULTY EQUIPMENTWITH...
