Hi,

Unfortunately I did not measure its size. Maybe you can extrapolate from this picture?

I'm finally finished with my first attempt

Did the 36dB version, but need a little more gain, so next one will be the 46dB. It seems i can just lift the voltage 4 volts, and change a few resistors. Should be easy. ( well, at least for some, i always find a way to mess up, hehe )

Thanks for making this possible Salas.

Hey, nice!

What kind of MM you have and you need more gain?

BTW nice compact PCBs. Are they final to post?

Actually i don't know what pick-up i'm using There's no name on it, so i suspect it's a cheap one, that someone put there long time ago.
BTW, my TT is an Akai AP-306t.
I know i need a new cartridge, but finances are a little tight at the moment, so i have to make the best of it for now.
I'm not really satisfied with the PCB yet. I have some issues with transistors being defined wrong in the library, and some things i have to define myself. Bit of a job, me being into car-repair, and not electronics, hehe.

Best regards
Ebbe

Did you notice any better turntable replay with what you already have?

P.S. There are really cheap MM out there, considered very good. Like Audio-Technica CN5625AL.

This what I am using at the moment.

Manufacturer: Audio Technica
Model: AT-110E
Cartridge Type: Moving Magnet
Output Voltage: 4.5 mv
Freq Response: 20Hz - 22kHz
Recommended Load Impedance: 47k ohms
L/R Separation > 25db db L/R Balance < 2db db
Stylus: Elliptical Cantilever Aluminum
Lateral Dynamic Compliance: 15 x 10-6 cm/Dyne

Could this be used with your standard circuit
This is one of those really cheap ones.

Thanks

The 110 is a long going favorite indeed. But since you jumped from the extra low budget $30 CN5625AL to the $70 territory, we must also not forget to mention the Grado Black for $60.
