Hello,
I'm using the Elenco FG-500 function generator kit, and when looking at the output on a scope, the sine wave is clearly sitting about 3V above ground. When the output is taken with a DC voltmeter, I get about that. Anyone have any thoughts about this?
The schematic is on page 3 of this PDF:

My thoughts were that there must be some unwanted capacitance in the output circuit, and it was the case that C7 was backwards, but after switching it I still have the same problem.
Thanks
