The voltage invertor circuit uses 2 transistors 2SD1213. One of them is damaged. I've replaced the transistors and disconnected the power supply part from the amp part. On 13V it takes over 700 mA and the output is +/- 40V, but the resistors connected from the transistor bases to ground are heating and then damaged. Where is the problem ?

Thx in advance !!!
