[sdiy] multiplier help

[Michael Ruberto]

I thought I had my multiplier circuit working properly until I tried to add 
another octave. see schematic:
http://frankentron.freezope.org/multiplier.gif

the circuit works, I put in 150Hz and it gives 300Hz. unfortunately when I 
try to daisychain the signal into an identical next stage I still get 300Hz 
instead of 600Hz. >:-(
I don't have an oscilloscope at my disposal so I tried to sim the circuit in 
EJB. however, EJB simply doesn't get it.

any suggestions?
