The Tap in Heat sink was done with Hand Tools because it is one of the most expensive part of Amplifier and i dont want to take risk of breaking tap.


Rest Tapping done in Aluminum Angles and Base Plate below were done with Torque Screw Driver. (Chinese One)

Thanks for the update. The amp looks gorgeous. How did you make the top plate vents? I'm also looking for ideas for my upcoming class a amp.

Your amp has come out very well, Sadik ji. I must listen to it on my next visit to Vadodara. Which transistors are you using in the output stages?

Sure Sir, Just confirm me the dates. The outputs are NJW0281 & NJW0302 one of the beset sounding Transistors.

Excellent!! Great job, Sadik. Hope to see and hear it someday.

Thanks a lot.

Do you have to match the transistors? If so, multiple pairs should be purchased to get a good match.

Sorry I have been missing the action here for some time...
Very happy to see the fantastic conclusion!
Congrats on the successful and unique build, Sadik-ji! Hope you're climbing the steps slowly to Seventh Heaven...Audio Nirvana!!

What about making your PCB available? Of course, I am interested. Do send mail when free.

Warm regards,
