Hey!

Hope someone can point me in the right direction.
I have a Roadster and the spongy side won't turn on. The bold side is fine and works.
What do I need to replace/fix to get the spongy side to turn on and be functional again?

Thanks for any and all help!
 
Spongy is simply another tap on the primary side of the power transformer. There is no circuitry, the switch just swaps between the two primary taps.

Is this a newly bought amp that came this way, or did this just happen to a normally functioning amp?

If the amp is essentially off when in the Spongy power switch position there can be only three possible scenario's:

1) Bad power switch or bad connection to switch.
2) Broken/damaged primary tap in the power transformer.
3) Power Transformer was changed to the wrong type.
