Had been running an all stock Cornet2. Just upgraded C200, C206, and C208 to Obbligato Premium 1.0uF; C203 to FT-3 0.1uF; 47nF and 1nF RIAA caps to K40Y9.
Will let the caps break in for 20 hours to see what happens. When they all settled in, I'll be bypassing C200, C206 and C208 with FT-3.
Thanks to all members for providing courage to build the Cornet and the subsequent cap upgrades. Special thanks to Jim Howard for FT-3 and K40Y9 recommendations.
