SX-1050 BOM AWG-020? - answered

Curmudgeon Electronicist
In the post quoted below, from a while back, an AWG-020 board is listed in one section ( in red ), without an identifying board header. I don't have an AWG-020 board listed in the documentation I have on the SX-1050. It appears on a couple other BOMs from the past as well. I just started my own SX-1050 refub/restore and don't have a clue, please help me understand :confused: where this comes from . . .

The service manual on page 25 identifies the EQ amp as AWF-020.

Edit - probably a typo on that BOM is all.

Thanks for your reply.
AWF-020 matches all my docs, including the schematic. Things change sometimes . . .
That was my suspicion as well, but I wanted to more information than I had.
 
It's a typo, and if you compare the transistor numbers next to it, you will see that it is the AWF-020 phono (equalizer) amp.

Mine are ok (i checked), and I won't point fingers publicly at a very reliable source's typo. I sent him a PM, to backtrack his records.

Thank you for your response, was not interested in pointless finger pointing |:rflmao:|, just wanted to be sure I had the correct info. I did not know where it originated, but I had seen it was not present in yours. I am renewing my SX-1050 I bought new and did not want to muck it up.
