James:
 I was hoping to get some advice on  using the phono stage in my Bryston .5B Preamplifier to gain the best perfomance from it.
I'm using a Rega P-1 'table,& find my self wanting a bit more gain than my .5B offers,so I'm using a tube buffer between the 2 units.Although it boosts the phono signal, I'm finding there is a bit of hum when the volume is turned up past about 9:00.
Is there any way to cut back on this? My outlets are all 3-prong grounded.I tried the "cheater plug"
but no luck..
Any advice you can offer is greatly appreciated.
 Regards,
Patrick

Hi Patrick - there is aways a balance between GAIN and NOISE but remember that our preamp is running full out Class A and you are attenuating the signal with the volume control on the preamp.  So do not let the fact that your running the volume control on the .5B at say 2-3 oclock.  That being said we could maybe increase the gain in the phono stage for you another 6dB if you want.

Thanks for the advice, James.
 Another concern of mine is will the hum damage anything in the long term?
I meant to ask, does it make a big difference which Phono ctg is being used? I'm using a AT 95E,which is a pretty decent CTG for the price.. ..
So I guess my question is will the gain increase if I use a "better" MM ctg?

 P.S:
 I was able to pick up an Older 3B (1990). This thing is still going strong!
Sounds really good,and built like a small anvil!

No harm can be done and a higher ouput cartridge will certainly give you more gain (volume)
