meter distribution card

[lukeaudio]

hi guys .....continuing with the repair of my console (ssl 8000 gb ) I found a problem  with the meter distribution card..
When I bought the console the owner warned me that this card(82e237) was broken..
first thing that happened was, that the chip 285502a4 was thrown aside
when I try to put it, I realized that there were several ways to do this but I do not know which is the correct way to connect it, I don't have the  schematic of this card so I do not know if it's two or three chips etc...

I also want to know if anyone has these chips (285502a4 ) for sale..please let me know

Hi, you can actually set this card up to work without the hybrids, but it takes a little re-routing.

Only LF and RF (ST1) and Mono are de-balanced via the hybrids, but in each case a standard buffer is present for these circuits.. A link change activates these, but they input on different pins, so this would need to be changed.

Run mine without hybrids.. and have them for sale!

It's worth getting the 4000G service manual from this site, 99% will relate to your console in terms of servicing.
