Re ZVP3310 -- perhaps he was referring to the "twitchiness" of the PMOS -- I think that the Papa had recommended a substitute, but it's buried in thousands of posts. It isn't difficult to fry this PMOS.
I agree, and have replaced a few. The easy solution is to have a few extra on hand when building.
Maybe not the most elegant solution, but once it’s in and working they are fine.

Hi. The Pearl 2 Boards are on their way to Germany and I'm collecting parts now.
Question: For the Power Supply: is it recommended to use a dual supply (left/ right channel with own trafo,..)?
And just one comment on ESD damage: I saw some of you having components laying on Sheets of paper: this can Generate Lots of "static" volts, destroying sensitive components. Buy some static dissipative bags if you really need the paper there and put them inside these bags. Better: have an ESD-mat properly grounded on your desk as base and store the Papers somewhere Else.
Kind regards

Dual mono is not necessary.
Separate PSU enclosure is necessary - Pearl 2 is very sensitive to transformer hum and the RIAA chassis needs to be 1M from any transformer, particularly it’s own.

Absolutely beautiful!!
BTW, you will have noise if you run the Pearl 2 with the RIAA chassis sitting atop the PSU. Put the PSU on a shelf far away.

I’m just blown away how good the sound is. Dead quiet. I’m listening to Dick Johnson & Dave McKenna “Spider’s Blues” recorded at Coast Records April 1980 through Ortofon blue (5.5mv), Wayne’s 2018 pre, and mono block Alpha J’s. Very detailed, bass is very accurate, mids/highs very realistic. Dead quiet.
Thanks Mr Colburn & Pass Labs & DIY store. Also, for this forum and I can’t forget this new look… just fabulous, thanks Jason!!

Can I ask what loading resistors you have set for your 5.5mv MM cartridge as i have a similar output im using ?
