    2016 HXDA 50 watt blowing 500ma fuses

    I own a 2016 PRS HXDA head that has blown the two 500ma fuses on the main board twice now. It appears to be random as it happened about 6 months apart. I am using NOS Mullard D getter EL34's that test in the new range on my B&K 707 tester. Please Help!!!
