Hi all again!!
I have another doubt with these 82E201 cards. There are some LF351 op-amps on our 82E201 cards, but they are installed (by someone) in different sockets (comparing between different cards) and I am not sure where should go LF351 ICs and where NE5534. As far as I undesrtand:
-IC T2, 4, 6, 8, 9, 10, (11)??, 17 and 18 are NE5534.
-IC T19 and T20 are TL072.
-T16 must be TL074.
- T1, 3, 12, 13, 14 and 15 are Hybrid op-amps
- T5 and T7 are LF351
Could someone check the attached schematics and give the opinion? I am talking about 82E201_rev3 cards (old version from around 1985).
Thanks in advance.
Best regards.
