Mike, I have a passion for fusing so quite interested how you determined 250mA, and what type/model fuse you chose.
Ciao, Tim

I didn't determine the 250mA - I was just citing the OP's reference in post #32 to the official Quad mod - which he says specified 250mA. I just assumed that Quad knew what they were doing (though not enough to have incorporated a fuse in the original design!). I assume it would be slow-blow to allow for charging current to the reservoir cap.
