Help with an Unknown Circuit Board

 

Hello,

I have this unknown circuit board, specifically the amp section.  It is the classic A/B Transformer push-pull circuit untilizing 1 x AC125, 1 x AC126, and x AC128's.

The only marking on the board is 022 c.

I was wondering if anyone here might recognize this particular board or have any idea on what set it might have come out of?

Looks to me to be of 1963-1966 era...possibly from a Philips? 

I am not sure if it is from a radio, tape or record player.

Any opinions would be greatly appreciated.

Thanks!

 

 

This picture was only about 3 mm wide - but by editing you could "tease" it as I have done now, so that something is really visible. Please ask a moderator if you have any difficulties, handling the forum. Thanks.

Greg,

We cannot see any details of the board so that is why we cannot help!

You seem to have edited the picture so that there are only a few pixels in width and also it looks as if the vertical framing covers a lot more than the board.

Perhaps you can make a better picture so that we can help.

If you have problems with editing the picture, you are welcome to contact me directly by email.

Regards

Roy

I copied the picture in post 2 to Word. So the board was visible.

This picture now ist 560 pixels wide and has merely 20.6 KB.

The original picture in post 2 has a size of 1006,71KB, however, it is only 41px wide and 231px high - very strange indeed, and a huge waste of capacity on the server.

Please format pictures for use in the forum alsways in a way that they never exceed a size of 40KB and become not broader than 590px!

Best regards,

Dietmar
