In Reply to: Question about Marantz 7 circuit posted by Tube747 on February 3, 2025 at 03:37:48:
I found a place who offers constant current source.
Here what he said:
"You could use a CCS on the plate of the first 12AX7 section, and also on the cathode of the 12AU7 cathode follower without disrupting anything. Not so clear on the second 12AX7 section - it may have some effect on the EQ. Probably not a huge change though?.......it would work there. The JFET version with low current is best for the 12AX7, since it only is running 1-2 mA typically."
Any thoughts
