All -

Just about finished a Xenon restore. The bottom three resistors on the vocalizer have been replaced, but the heatsink on the transistor as well as some chips are getting VERY hot (heatsink almost too hot to touch) after abotu five minutes in attract mode.

Shortly thereafter, the sound cuts out and all I get is a hum.

I searched pinside and google in general but did not find anything specific. Pinwiki has a reference to vids guide for swapping PROMS and a placeholder.

Thoughts?

Thanks -
