Do be aware that the LM317T has an absolute maximum 'Vin to Vout' voltage of 40 Volts. This is used to create the 60V HV output. A simple short on the output of that regulator will put a differential of about 90V across the regulator -- about 2.25x the absolute maximum. So be real careful to not short the HV supply or you'll be replacing this regulator again.
