Hi Friends,
I am sharing my new built Class AB amplifier with ThermalTrak transistors. These circuit and PCB is designed by our Forum Member Mr. @Aniket It was a very slow built & took almost a year to complete it, as i was busy with other projects.
We have named this Amplifier "PINNACLE AB200". There are in total 5 PCBs manufactured. Three kits will be built and remaining two will be in spare.
Specifications are as under.
Power : 250 Watts @ 4 Ohms, 150W @ 8 Ohms, continuous average power output, both channels driven
Dynamic unclipped power output : 165W, 320W, 600W into 8,4,2 ohms
THD: <0.005% 20-20000Hz, @ 200W into 4 ohms, 0.0006%, 1kHz @ 50W into 4 ohms
Frequency response: 5Hz-300kHz (-3dB)
Signal to noise ratio: 115dB
Damping factor: >500, 20-500Hz @ 8 ohms
Slew Rate: 95V/us
Sensitivity: 0.9V rms for rated power
Transformer Rating : 40-0-40 V AC / 600 VA
Total Capacitance Bank : 60,000uf(min) for both channels.
For Any other details Mr. @Aniket will join in as he is the designer of this Amplifier & I am only the assembler. My knowledge is very limited i may not able to answer all questions.
Both the channels including power supply bank and speaker protection kit is on single board which makes wiring very less.
Enjoy the below Pics.

Finally Testing & The Amp is singing.
Face Plate is yet to be made. I will upload final external photos once i finish with the face plate.
As far as my reviews are concern, It is the second most best sounding Amplifier from all my built till date. (First is my Class A Amplifier Jean Hiraga Super 30).
I cannot define its sound just by words, because defining by words will not do the justice to its sound signature one has to hear it and decide by themself. I really thank Aniket for this wonderful design of Amplifier. & I would also thank Mr. Harjindersingh (he is not on our forum) who took gave us these transistors (without any charges) to make this amplifier.
