Thanks for your input, it helped me confirm the fault.
You see, I placed an order for the parts using the updated BOM with the new BJT and JFET.
However upon assembly, I followed the default BOM on page 1 of this thread and wondered why I had bought 2.2k 1% resistors and no 1K 1% ones and same for R4 and R5. And did not realize the values I ordered were for the correct JFETS and BJT that are available at this time. So i pulled 1 K from another board I had lying around, and went camping. Now i realize that i made the rookie mistake of thinking i made a rookie mistake.
Looking through the thread I realized my mistake, replaced the resistors with the correct values and my PCA is back to Hand Warmer mode again. I have to say though, i really like the overclocked performance with 20V haha
Can I ask, at this moment I feel that when I am using the PCA, i feel the bass can be a bit lacking. I gain much better control over the LCD 2 bass when driving the amp at 20 Volts.
My question is, what caps should i upgrade, and which ones in this design will cause the most difference when driving the somewhat hungry LCD 2?
Now I know what you will say, that the amp is able to power the LCD 2 amazingly, however I want the deep bass extension, and was checking out this amp with my LCD 2 listening to tracks like Bass I love You Bass Boosted, Hideho Tropkillaz, Bass boosted. I dee that every time the bass needs to rumble, my current usage on the amp goes up which is to be expected. But at this point i'd like more capacitance to rely less on the power supply for those transients.
Please feel free to correct me if I am wrong, as I imagine I can very easily be, in my expectations or understanding
