Tube Cheat Sheet
« on: August 23, 2014, 07:30:32 pm »
Hi guys, I just want to confirm that the cheat sheet that contains the current draw on the heaters is incorrect.

I have a pair of Philips 6CA7s and the data sheet say that 6CA7/EL34 draw 1.5A/tube and the cheat sheet says 1A.Thanks

1.5A for either tube. cheat sheet has error. svetlana datasheet says 1.6A. close enough.
