where to get schematic for Artemis Lab PH-1

Thanks Salectric for your email! Much appreciated. I should be back home next Tuesday and will take a closer look at things then. Thank you for taking the time to try and help...you are a true gentleman!

You are certainly welcome. I hope you are successful in getting rid of the hum.

Dave Slagle sent me the schematic! I am dropping my PH-1 off at my local guitar amp technician next Monday the 26th. I will let you know what he finds that is causing the right channel hum.

It appears that the hum was caused by the ZIF socket cover being loose.  All the internal components were fine. It is again quiet and I am enjoying having back in my system.

Hi martrabar!

Thank you for your followup post and sharing what the solution was for your problem.

This is very interesting.  I often run mine without the ZIF cover on as I like to experiment with different loading from time to time and this just makes it easier for me.

My health hasn't been well for the last couple of months and had to under go some very invasive surgery.  I will be laid up and will be quite immobile for several more weeks so I will not be able to test this theory out for my own situation until I recover.  What a fantastic and easy solution if it truly does work.  Thank you so much for sharing this info with us all!

Best wishes for a very Merry Christmas and Happy New Year!
