Help !

I am about to change cartridges on my aged Gyrodec, but I need some advice on which dip switch settings to use on my Sedley Phono Stage with an Ortofon MC30 Supreme?

yes no problem..if you give us the specification we can guide you in th right direction.

Dear Haider,
Thanks for the assistance in advance, here's the spec:-
Mounting standard 1/2" Weight 10.7g
Stylus Super Fine Line 6 x 80µm
Frequency Response 20Hz-40kHz
Equivalent Stylus Tip Mass 0.35mg
Cantilever Aluminium
Output Voltage >500µV
Channel Separation >27 dB
Channel Balance <1.0 dB
Tracking Force 1.8-2.2g
Dynamic Compliance lateral/vertical 16/16 µm/mN
Load Impedance >20 ohms

Dear Ian,

Thanks for the spec.

Ok..Your best bet is to start by setting both channels to 1k ohms resistance. You do this by having the 1k switch on both left and right in the down position.

The capacitance may require a little fiddling. To start I would try 100pF setting. It is worth experimenting with higher and lower values of capacitance.

Please get back to us once you've tried these.

Best of luck.

Haider.

Dear Chaps,

Another cartridge challenge for you.

Just bought a Dynavector DV20XH (High Output MC - 2.5mV).

If I set capacitance too low when at 47K and in Moving Magnet Gain, then I get what sounds like radio moscow bleeding over everything, even when the needle isn't on an LP. Upping capacitance seems to calm things down.

Is this normal ?

The Kit spec is:

Gyrodec QC
Origin Live RB300 with Incognito Loom
Sedley Phono
Chord Chorus Interconnects
Primare 30.1 Integrated Amp
Dynaudio Audio 62's
