[QUOTE="Crankshaft, post: 981483, member: 941"] Hi I have a series resistor in the HT line of the STA25 - as per Radfords recomendation to reduce transformer buzz. It was a fairly hefty 20 watt component, but after a few weeks it failed - popped open on one side. Now, before I just replace it, or remove it, I'm wondering if the failure is a result of the amplifier drawing too much current. I completely rebuild the amp recently, so it is possible that I made a mistake somewhere. Searched plenty, but cannot find the HT current that the amp should draw. Anyone able to help. Fitted with EL34 valves. [/QUOTE]
