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

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,

Bad news: Sorry, I have no experience with the 6GH8 tube.


Good news: However, a quick web search shows that they appear to be inexpensive to replace. Lots cheaper than the 12AU7 or 12AX7!
