7:56: You remind me "Wakko", from "Animaniacs" 🤣 Best regards, nice videos!

Definitely you need a more powerful transformer for this amp
Not really sure what you mean; if you mean in terms of current, not really. The amplifier only draws around 2A at full power. If you mean in terms of voltage; you can't go any higher than +/-40V with current signal transistors.
@@AstrosElectronicsLab the one you used on the video how many VA have that transformer?
@@SymbolTech21 160VA
@@AstrosElectronicsLab if it's 160va should be fine I don't know why I had impression from the video was looking quite a small size
@SymbolTech21 nah, it's 110mm diameter, 3A secondary winding.
Hi there
I have 1 question
Which one is good for Heat sinks
1. Anodizing
Or
2. Powder Coating
For amplifiers around 200 watts per channel.
Please reply
Thanks
The coating doesn't matter, as long as the material is aluminium (aluminum). Most heatsinks are anodized; however, I wouldn't use powder-coated as this can affect the heat transfer as it's basically a plastic (polymer). The surface where the devices mount, it'd be better if this was bare (natural); most effective heat transfer.
@@AstrosElectronicsLab thanks a lot
I appreciate
