i have still some doubts......the 1009 and 1010 have very different ratios and impedance......have i to mod something to put in these transformers....?
the 1009 (replacement for the A-10, which has a turns of 1:10) has a ratio of 1:9 which is closer to the A-10 than the 4383 which has a ratio of 1:4. The inputs are all 600:50K, so that isn't the problem.
I have encountered this issue as the symptom of
massive amounts of gain.
So far may edit list to do is the 25k gain pot mod and using 12AU7s in the first stage instead of 12AX7s.
If anyone has any similar issues or suggestions, I'm all ears....
When I get to this mod, I'll report back.
Cheers!
