Glad your happy.
One point though. To increase the Negative feedback you lower the resistor value. To reduce the amount of feedback you increase the resistor value. To remove the NFB you disconnect the resistor, leave the circuit open. you can put a control pot in place of the resistor and have a variable Negative Feedback control and dial it in. I like to put a lower value resistor in series with say a 100k pot. You have to look at the ratio to see what values might be good. I have used a 250K pot too and its like no NFB when max resistance is applied.

Yup Billyz,

I am looking for less GNFB so I installed the 100K as opposed to the 56K.
Might want to go to a higher value but I won't be able to crank it yet to see - waiting for my significant other to vamoose!

Hopefully later today!
