Found some time to play with my latest acquisition, three EMG TR-0463 function generators.
I posted in the "what did you buy today" thread, that the packing job was incredibly lousy. One of the units does not do its signal generation thing, but the modulation part of the circuit is still OK.
Apart from some scratches and dings, three pot knobs broke. However, the seller apologized and sent me back quite a decent amount of coin. I would still have preferred getting three units in good shape for the full amount of money, but oh well... Now the two working ones have been an exceptional bargain and I know the other one is repairable.
I managed to find a copy of the full manual with schematics and theory of operation - all praise the interwebs!
There is some maintenance and calibration that needs to be done, but all in all these do not look to shabby for working on my audio gear

Here are some quick screenshots from the output with sine and square amplitude modulation, because: Squiggly lines!
Why is it, that I am so heavily attracted by early 1980s gear? ... These function generators, my Oltronix LabPacs, HP 16C, Fluke 80xx meters, Sennheiser and AKG headphones from that time,...
