Yes that's what I meant,2 boards (stereo).Also my friend was asking about very PSU unit,protection and such.
Can you please give me your mail ID,so that I can ask him mail you directly.or you prefer he call you on the number ??
Hi Shaan,
The PCBs are complete & Mounted on Heat Sink. As per your tips i have removed the 470ohms resistor & instead of 15K i have used 27k resistor. & rest modifications are done as per your tips given.

Hi.
I am going to have a bunch of power amp PCBs but not PSU or protection this time.
You can either mail or call me regarding this.
Hi Sadik.
Try to install small flag type or U shaped heatsinks to the VAS transistors. They overheat quite quickly if no heatsink is installed.
Continued...
The 100uF caps near the 2200uF look a bit smaller than they should be. Make sure their voltage rating is higher than PS voltage, same with all other electros except the input(10uF) and feedback(2200uF) caps.

Hello Brothers!
Just received the V1.1 and V2 boards this morning.
V1.1 is my favorite so assembled one essentially instantly.
Component placing is like a breeze and instantly it begins singing.
The series offset control was indeed a step forward, took about 10 seconds to trim offset to zero and it stays there. It's now a rock-stable amplifier from its very start.
In the evening going to populate the V2 boards. Stay tuned!
Some shots:
The packs
V1 vs V1.1
35 vs 70
With parts
V2 shot
(more coming)

Waiting for the feedback on V2. Depending on that I might go for either of them (v1.1 or v2)
Buy from India's official online dealer!
