Yes, I agree - "modern" sources like CD or DVD are often "hot" and A~16 can be too much... However, I`m sure that those good people here will definitely come to hate you after this...:-) The only chance you can redeem yourself is to make Hg-rectifier (866?) PS (say of "Guinevere" PT- 2x400V), we need exactly B+=304V, haha (9V drop through OPT with Rw=150 Ohms, Uak=250V, Ugk=45V). Current draw - 60mA for the output tube, 8-15 mA for the driver....
