K8060 transformer question


I was woundering if one could use a 2x40V@2A tranformer or would that fry the amp?
What could be changed to make the amp work with 40V?
If i’m not mistaken the tip142/147 can deal with up to 100V.

Thank you.

Prolonged use at high power output might cause premature wear or failure, so we do not recommend to use a higher voltage than indicated.
