We did it bois - saw waves!

After tracing every single little component across the entire circuit it finally dawned on me to check my power supply. Who’da thunk it - it’s POSITIVE ONLY!! Here I was thinking the negative symbol meant negative voltage but nope.

I then hooked up some batteries and wham - I get perfect tunable saw waves.

Question is - should I return this single bench supply and get a dual bench supply or are y’all getting +- voltages a cheaper way? Should I just set up a voltage divider w/ +18v to achieve +-9v?

Appreciate all the insight and assistance for this (extreme) noob!
