Default Cheap Sakura Hybrid Tube Amp Modification

I finished my final tweak in Sakura Hybrid Tube Amp. I said final because, this is the best tweak I've ever heard. Every details from the music played from the cdp were unveiled from this simple but powerful modification. The ideas came from Mel and the guts of doing the experiment in Sakura was by myself. The You Tube video is just to give an idea on the improvement. However, the actual listening session is better sounding, of course.

Thanks for viewing folks.

Note: The tweaks were supervise by rascal 101 of Pinoy DVD Philippines.

I'm not going to go into the details but the tweaks were on improving the drive circuit of the transistor based power amp of the Sakura AV-200 hybrid amplifier. Essentially, it is a way to reduce the effects of Miller capacitance.

What speakers are you using? I have a tweaked US $2.00 speaker and it sounds excellent to me.

Yeah right, that's why you should use better one (PC Speakers). I use only Bose Companion 2 computer speakers. Better to try to use a good quality headphone. Thanks for the comment. You Tube Video is not reliable on listening test but can give some idea how it sound. At least it doesn't sounds like tin can.

What a cool thread. Would it be possible to make clips pre- and post- tweak of the same track, so we can compare the sound? What kind of mains cables are you using? Sounds a bit like Shunyata Python in the bass.

Can your camera choose a higher quality recording? On my Sony it has the option for different video resolutions and audio encoding bitrate + frequency.

Thanks for the comment. Sorry, I can't no longer do the recording without the tweak. The cables I am using is D.I.Y magnet wire gauge 21 for the signal and gauge 18 for the ground. You can experiment which gauge you prefer. Yes, the overall frequencies were improved after the tweak. But the sound is better of course in actual listening session.

Sorry, my Sony video cam is Digital 8 series. It's the last model before Sony went to Hard Disc type video cam. I just use Memory Stick Pro to record it.
