Ok- I set the Rogers Phono Pre per Charisma rec.-"We would suggest you to try the 100 Ohm and 10K Ohm of the resistive selection. Capacitance is sensitive to moving magnet cartridges, but not moving coil."

I get very low volume even with the Wyetech preamp at full volume- Please help a Newbee out- What am I doing wrong??thanks gary

How much gain does the Rogers phono stage put out? If I understand from above the 12AU7 puts out 50db gain, but switching to the 12AX7 results in 65db gain...correct? If so, 65db should be plenty of gain to drive the .4mv output cartridge. 
Absolutely no need to consider switching to a moving magnet! You've got a simple wiring error or a bad tube in all likelihood.

And for god's sake, never any need to turn the volume all the way up. If you pass 2:00 and it's not plenty loud, usually something is setup incorrectly.

If you have a buddy with tube tester,or a local dealer who can test your tubes it would be good to confirm that's the problem. However, most local dealers will have little tube selection. Cheers,
