Stereomour II / Re: Another failed voltage check

Interesting. I would, at a minimum, have to add 4 switch mounting holes to the top plate of the amp in order to set up an ohm switching option. Do you think hmbscotts 4PDT would work on the Kaiju?
I will have to check your diagram for your 4PDT switch set up for the Stereomour II and see if its wiring is similar to the Kaiju's outputs.
I implemented a switched speaker impedance set up on my Stereomour II thats documented in the Stereomour forum see the topic “Stereomour II mods”. I used two 4PDT switches. My wiring diagram is posted in the finial post of that thread. It works great and allows me to switch the speaker outs between 2, 4, 8 and 16 ohm. I did build a custom chassis plate to enable me to mount the switch accessible from the top side of the chassis. I’m not sure if the Sereomour and Kaiju output transformers are the same, so my Stereomour wiring diagram might not be applicable to the Kaiju.
As Paul suggests, it would be impossible to add a second pair of binding posts and have fixed wiring such that the first pair is wired for 8 ohm and the second pair is wired for 4 ohm. Because, the transformer requires a different configuration of jumpers when wired for 4 vs 8 ohm. The only way to accomplish that required change in jumpers is with switching.
