Hi
In the Copland CTA 301 there are 4 tubes in the phono preamp stage and 2 in the main preamplifier. For the 2 in the main preamplifier does anyone know if each tube is a channel or if each tube is a stage in the amplifier chain (meaning one tube contains both left and right channels)?
The way the board is laid out it looks like each tube is a stage but according to the schematic it looks like each tube is a whole channel. Anyone know for sure?

:D :D ROVA :D :D
