Edwards Audio MC3 MM/MC Phono Stage

[khapahk]

I need to have a “spring clean” and there will a number of items coming up for sale shortly !

I have been the only owner and purchased it from Deco Audio, Aylesbury, in 2012. The photographs below demonstrate the excellent condition of both the PSU and the amplifier itself. I haven't used it in anger for about two years now but it is still in full working order.

This design has very flexible loading and gain adjustment, undertaken using two banks of internal jumpers, one bank for each channel. I have used it successfully with both MM and MC cartridges, including Goldring G1042, Lyra Lydian Beta, Benz Micro ACE SM and Benz Micro Wood SL. In addition, there is a mono switching facility on the back of the unit.

The PSU comes with the manufacturer-supplied standard IEC connector and there is a separate 1 metre umbilical connector between the PSU and amplifier, as shown in one of the photographs.

The following information is from the manual:-

Max Input MC................................................ .................................................. .....................10mV
Nominal Input .................................................. .................................................. ..............0.1-1mV
Max Gain MC input (MM).............................................. .............................................73dB (40dB)
THD Distortion .................................................. ..........................<0.006% 1kHz - <0.02% 20kHz
Signal to noise............................................. .................................................. ....-80dB A-Weighted
RIAA .................................................. .................................................. .....................within 0.25dB
Frequency response* .................................................. .............................20-100kHz within 0.3dB
Stereo separation better than .................................................. ............................55dB - 20-20kHz
Input Loading MC/MM................................................ ....................100R with 2n2/47K with 120pF
Output impedance ............................................ .................................................. ..........<10 Ohms
Nominal output............................................ .................................................. ...............100mV - 1V
Max output level .................................................. .................................9.8v depending upon input
Dimensions WxHxL............................................. .............................114.5mm x 47.5mm x 160mm
Weight............................................ .................. .................................................. ...................3.5kg
Power consumption (Max)............................................. .................................................. ........3.5W

I have a pdf of the manual and will be happy to email it to prospective purchasers.

I am looking for £450 plus p/p at cost, although I would much prefer collection from Linslade, Beds, LU7. I could demonstrate then if required.

Lived with one of these for a couple of years ... ime a really good solid-state phonostage. New, they are one and a half grand, so this is a real bargain.

The internal dip switches allow 6 different settings of mc gain, and also another 6 for mc loading. There are also 6 settings for capacitance, which never made much difference ime. I found the mm input to work really well with a SUT ... accurate, precise and dead quiet. The earth lift was extremely useful in my system at the time, reducing hum to negligable levels. Mono switch got used quite a bit, too ...
