Phono amp gain too high? (EAR 834p)

@randyhat
If the EAR has a separate gain tube then that is the only one you would need to replace. If not you can replace the 3 tubes with 5751’s. My phono has a gain tube so I only replaced that one tube to lower the gain. Here is the info about a 5751 tube!

Second yogiboy's suggestion.  I have a trio of nos GE triple mica 5751's that I rotate in my modified (Singerman) 834P and can verify that they do noticeably reduced gain although I sometimes use them because I like their sound in the preamp not because I need to reduce the gain.  Not terribly expensive and I found them to be pretty available a couple of years ago.  

Frank Van Alstine used 5751's in his redesign of the Dynaco PAS 3, preferring it's gain structure, low noise, and distortion characteristics to the stock PAS' 12AX7.

As do about 3/4 of people with long tube experience .
Main reason I bought tube pre with gain nob, hit that sweet spot for 5751's.

In case anyone is still replying to this thread, everyone here knows more than I do about gain issues in analog! I have a koetsu black on its way (output .45 or .5 measured, people claim) and currently run a Denon ha-500 head amp with 24 or 36 dB switchable gain going into an EAR 834p mm only, without volume control. I run it at 24 dB. Should I be worried about the gain overloading my Thor ta-1000 linestage preamp? Certainly I wish the volume control of Thor could get past 10 o'clock but with cartridges in this output range it won't. But the volume control position is a small concern compared to an "overload" risk, which I don't really understand.

Thanks for any thoughts.
