I have a circuit that I have been designing that uses Quantity 6 555 timers to generate frequencies from 6Hz to 460Hz which needs to be mixed using 8 op-amps such as LM741 or LF351 or TL071 or NE5534 op-amps. The final output needs to have 8-ohn impedence for input into another circuit. More design specs available upon request.
