Help with op amp alternatives and spice so i can graduate

negativecreep · 12th February 2004, 04:31 PM

I am trying to build SS amp similar to a fender frontman link the amp uses 4560 TL072 and TDA2050 op amps. Since im not trying to do a direct build, but a variation i would like some suggestions on differant op amps that would be a good replacement for any of the above op amps. Also i need to do a spice simulation and have been unable to find the spice models for these amplifiers. I am using circuitmaker 2000 because the node limit on pspice. Also I was thinking of adding maybe a five band equalizer instead of the regular tone nobs, if anyone has any adivice on what IC to use. /I would like to try and keep all the Vcc to be either 15V or 23 V so I can keep the same AC-DC rectifier. Also any other sugestions for modifications to the circuit would be appreciated.

Thanks
