Fixed Bias Supply Voltage

In the manual it states that the bias supply should be -50V in the power up test. I would like to change this to -70V, the bias supply caps are 250V rated so this should not be a problem. Are there a couple of parts I could change in the supply to get this higher voltage?

Thanks

Most likely it will go that high to begin with , if it doesn't change C18 a .1uf cap to .15 uf and you will get the voltage you desire
