RE: SUN SV 2A3 stereo SE amp .... MEASUREMENTS
Posted by drlowmu on April 25, 2015 at 15:49:12:
His circuit is -5 dB at 20K with his not-to-my-specified bypassing.
I contend, with a DC two stage amp, it is possible to get 4 dB back Dave !!!
Careful Rk multiple film cap bypassing, of not only the 12AX7 half, but also the Rk for the 2A3. NEITHER stage's Rk was built by him as was suggested, and one can not leave this out.
Allow rage to do that and re-measure his frequency response for us all.
