Hi!
Wanting to re-design an old amplifier I came across the Rod Elliot Project 3A witch fits very well.
Would it be possible to parallell two pairs of output devices? Im thinking to use TIP3055/2955 since I have them around, and connect them as in the earlier project 03 "figure 2".
Anyone done this??

Yes, just put in some 0.1 ohm current sharing resistors. I tried a Altman split feed back experiment with 3 sets in parrellel. The first set to an 8 ohm load and the last 2 to the speaker. If you look at Rod's guitar amp he shows two in parrellel. Have fun, Mike.
It was interesting. You should try it. You can change the sound of the amp depending on the load.
Doesn't that cause strange things to happen as the impedance of a speaker is changing with frequency?MikeW said:
Does the output impedance change with the altman topology?
Tell us more!
