I have a project to create a wien osc that has a 72v pkpk output on a 5.6 ohm load.I've managed to obtain the voltage peak to peak but it is not simetrical (+36 to -36).I need to add to this signal about 14 v.I've tried just changeing the dc voltage on the output but it messes up the circuit.I've also tried using a repetor made of an op amp and then adding the 14 v but with no succes.I've also tried a simple buffer....but nothing.I need an idea how to add the 14 v bun not to disturb the circuit...Hope you guys can help in time.I have to turn it in wensday evening
