I have for sale a few more PoPs, R1 this time.
These can be tuned to have more or less flavor so it can suit all tastes by changing a few key components in the front end. Depending on your taste you can mention what exactly you want, less flavor meaning less thd.
From the strongest flavored to the light flavored at some power levels the thd is half.
Please see the new thd graphs at the bottom of the post where I compare the same module setup in 2 different ways.
Since some time I go ahead with the Xa252 PoP being the reference amp in my system.
This time I built it a bit different than last time. I wanted an amp that can be tuned to more or less flavor so I got it.
I am using fqa28n15 and fqa36p15 in the ops.
It can work from +/-16v to +/-24.5v. Bias is preset at 1.4a
I call this PoP R1 and the schematic looks like this
Stable as before when handling square waves
The new pcb has same drill hole pattern as R0
And here some thd measurements
All modules are tested and working. If no preference for the thd the modules will ship with the stronger flavor.
Price for 2 channels 160€ + free shipping for now
