Is an LM324 a good replacement for an LM3900? I couldn't locate one of the latter so relayed my circuit to use an LM324 instead, well it doesn't work, i checked my output from the first stage and it sits at 10V although the input is a 4V p-p sine wave from my generator, i am building the circuit here:

I understand the LM3900 is no longer available, so what would be a good substitute?
cheers
