2012-01 Low Noise Phono System

I've always had a little hum on the record player. So low though that even quiet music obscures it.
However it is there and I recently got a copy of Tibetan Bells. TB is very quiet indeed, with long passages where a single bell note fades completely before the next is struck.

[1] Check the amp.

Amp:
Found the Tuner input on the amp, which I had been using had some hum. Checked them all: The Tape input is quietest by far.

Cables:
OK.

Record player:
Both check out fine.



OK, the pre-amp in the amp is noisy so I got a general preamp kit from jcar (http://www.jaycar.co.nz/productView.asp?ID=KC5159) to try. Cheap enough to discard if not good enough.
It sounds great. Housed it in an old power supply case and it goes directly to a spare input on the PC sound card.
I can easily hear the original tape noise kick in as the cutting engineer switches it in when mastering the LP on Tibetan Bells so the total noise in the system here is less then in the original studio (1970's analog) and there's no discernible hum at all. An added advantage here is there is no need to use any mechanical switches any more. I just use alsa mixer to directly control the sound-card input level and switch between inputs on the sound card.

Here's a photo of the finished pre-amp disguised as a pedestal.
