Uups.... I can only see two "3821" Chips - they are labeled "GG 3821N 7323". The other 8 
Chips seem to be all 741 OpAmps - is this right? They are looking different, two are on 
sockets, six are directly soldered. Can I swap the 3821 with brandnew 3046?
And: I found four Electrolyte Caps on my board - one 33µF, two 4,7 µF and one 2,2µF. All are 
on the left side over the left contact-row....
Board is marked "3251" with felt-marker.
Thanks + Greetings
