I have a Fender Super 60 combo that I may modify into a head. It has an 8ohm internal speaker and an aux output for another 8ohm. Am I correct in my thinking that if I disconnect the internal speaker that I should be okay driving a 4ohm cabinet?
Here's the generic wiring schematic for the Super60 series.

OT is tapped for 2, 4 and 8 ohms. Put an impedance selector on it and you can drive anything you want.

Unfortunately there is not much room in and around the upside down PCB on this thing. The notes at the bottom that say "4ohm or second 8ohm speaker only" lead me to believe that I will be okay with a 4ohm cab and no internal speaker.Firestorm wrote:OT is tapped for 2, 4 and 8 ohms.

Yes. That's what the schematic and the footnote imply.sonicmojo wrote:Am I correct in my thinking that if I disconnect the internal speaker that I should be okay driving a 4ohm cabinet?

Yes, the "speaker output 4 Ohm" is always 4 Ohm.
Be careful about trusting that schemo though, the "speaker output 8 ohm" is drawn wrong, it shows "NC".
I don't care so much for those "foolproof" jack switching schemes.
Usually too many switch contacts in series with the speaker.
At least in this case the 4 ohm jack's wired directly to it's tap.
