Default Re: Hope to start an audio amp with CV415/CV4046/TT15

Little bit of progress, the PSU is bolted together and there is HT and 6.3 internal to be used. I need to gain a grid bias supply so thinking of using a 5 Volt winding on the transformer through a couple of Cockcroft-Walton Voltage multiplier stages, to get around -30 to -40 Volts Bias line (Yes I have been reading a book again).
