unknown Pot on hitachi GMK-29FS3 Capcom impress - super Neo 29 chassis

Post by mukurop »

Could someone give me a hand with this acronym in Japanese? I replaced all the capacitors on this spare hitachi chassis for capcom impress but I noticed this pot and I would like to know what it does.


I have also another quastion about b+ pot, some years ago while I was servicing this chassy my son touched the b+ pot just the only one I have not marked, I have still not tested on cab and if the b + is out of place could it damage the chassi or the tube?

The top line of text next to it reads 'Side Pin'

There is already a pincushion pot on the chassis and work as intended, now what mean this "side pincushion" pot. I will try and report. Also I must say that usually this pot have glue on it like the B+ , almost to indicate that it should not be touched because already set.

You should only need to adjust this if you've swapped out the original tube to which the chassis was set up.
