If it says a 24v-0v-24v AND 9-12v then that is what is needs , it doesn"t say 24v-0v-24v and 24v ........

The 24v-0v-24v is used for the Poweramp and the Plate of the Tube , the 9v-12v is used for the heaters which is regulated to 6v with a lm7806 ....... if you use 24v you will fry the regulator .......

Get a transformer with an extra 9v-12v winding or use a seperate small transformer or even an AC wallmart ......
