C-26 phono capacitance?

[welltempered]

Hi all. I've searched and searched but I can't find it anywhere. Does anyone know the loading capacitance of the phono input in the C-26? Many thanks for your help.

The phono capacitance of my old C712 and my C45 are both 65 pF. I assume your C26 is the same.

Are you looking for input impedance or capacitance. The phono input impedance is 47k ohms per the owners manual.

"PHONO 1: Connects the output of any magnetic
phono cartridge to the low level input stage of the
C 26. The response has been shaped to compensate
for the characteristics of the magnetic phono
cartridge. The gain at 1000 Hz is 62 dB to the MAIN
outputs, 42 dB to the TAPE outputs. The input
impedance is 47,000 ohms.
PHONO 2: Same as PHONO 1."

Proper capacitance loading is very important for shaping the frequency response of moving magnet cartridges. Remember the cables + Tonearm wires + preamp = total capacitance load on your cartridge.
You can use a spare headshell and measure this with a capacitance meter one side at a time.
If it measures higher than your cartridge requires you may have to replace the turntable phono leads with low capacitance cables. I like canare L-2T2S low capacitance Mic cable.

Hi
Here is two cables that is lower in capacitance than Canares 70 pF/meter.

Supra cables by Jenvings, DAC interconnects 45pF/meter
Cardas Golden Ref interconnects is even lower.

Thanks

The goal should be matching what you cartridge needs as far as loading. Take say a Stanton cartridge, they are designed for 275 pf loading. This will give the designed frequency response. Less or more will change the response.
Low capacitance is a good idea with any of the low output moving coil cartridges. Less is best.

Belated thanks everyone. I've found it somewhere, it's supposedly 135pF.
