The voltages can't all be good if it's redplating.

I suggest using the form that's in the downloads section at http://18watt.com/storage/18_watt_volta ... mplate.doc" onclick="window.open(this.href);return false; Measure the voltages on both output tubes two ways. First, measure them when the amp is on but not being played then have someone else play the thing until you see signs of redplating then measure the voltages again. Post the measurements here.
