Hi,
I got this Altec 1592A from Ebay in a non-working condition.
It seems like everything works well beside the EQ section on the master channel.
I've opened it up and it seems like one of the legs on the EQ on / off switch is disconnected as well as the mid leg of the high frequency pot. (both marked in red circles) :
The only schematics I could find online was the schematics of the 1592B but it seems like the two models contains different 'tone control' and 'amp' boards so it don't really helps.
Does anyone who owns an 1592A mixer and could please open it up and see how the EQ on / off switch and the high frequency pot connected?
Or any one have the 1592A schematics and can help me with this issue?
Here's the schematic of the 1952B tone control (maybe that can give someone idea)
