How to increase gain of Pearl Phono?
The Pass Pearl phono stage is my first full DIY project from ground up. Hence I would consider myself a DIY newbie.
The Pearl was complete about a week ago and mated to my Rega Elyias MM cartridge. But I find that, with the Pearl in my set up, I need 3-5db more gain.
Can any helpfull soul please tell me what I need to do to get more gain?
BTW, I already did a search but did not find the specific answer.
Your help is highly appreciated.
Any one? please?:bawling:
For the sake of sharing, I've learnt that to increase the Pearl Phono gain is R19. It originaly has a value of 499R but I have increased the resistor value to 909R to get the desired gain.
Many thanks to Promithues for helping me out.
Hope this can help future Pearl builders who requires higher gain.
Lastly, many thanks to Nelson Pass for sharing this wonderfull design.
changing this resistor to 909R will also double the voltage drop over it. Watch out that the cascode is still working as it should or up the supply voltage for this gain stage.
