I gave this little guy a try but was deeply disappointed. As previously mentioned, there is no gain with this preamp. To listen at normal volume, my receiver volume was double normal volume. There was a bit of a fuss, I've read that others have opened up the chassis and provided better grounding, but it wasn't worth it. to bother me at all. Try your luck, I wasn't happy with the phono preamp as the aux line buffer was marked the same low gain. There may be better tubes out there than the ones supplied but I'm willing to bet this is a low B+ setup but without seeing the schematics I can't advise on how to improve its performance.
