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

fluffers,

If you have the Preamp outs connected to your Phono Pre, the Houston, we have a problem!  
Turntable cable goes to the phono pre 'in'. The phono pre 'out' goes to the Preamp phono 'in'.  Preamp 'out' goes to the amp.

It sounds like you have narrowed it down to bad tubes, since all connections seem to be correct.

Asking for tube recommendations can be tricky, as we don't know your budget or personal tastes.
Choosing tubes can be subjective, just like choosing cables.
NOS can be pricey, but worth it to some. Some like the warmer sound of Mullards/Brimars, etc., while others like more revealing tubes like Amperex/Siemens, etc.
Try to find a reputable dealer like Brent Jesse if buying NOS tubes.

Personally, I like Amperex NOS tubes, and if going with current production tubes, I like the Psvane tubes. Obviously, YMMV.

Let us know how you make out with some fresh tubes.

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,
