6C33C & Borbely Question

Status
Not open for further replies.
Hey folks, I'm trying to figure out a power supply for a monoblock of the Borbely 6C33C single ended design. Here's what is confusing me. I noticed that the B+ for the 6C33C anode is stated as being 500mA, in drawing a load line based on a 600Ohm transformer and +210V the max current is right at about 350mA. Am I crazy, or missing something? Shouldn't I be able to spec 350mA as the absolute peak current for this amp?

Any clarification would be appreciated 🙂
