Build a High Power Amplifier Using 20 Transistors - MICRO BOOSTRAP with M-270 BOX

PCBA from $0（Free Setup, Free Stencil）: jlcpcb.com/DYE
Hi friends, in this video I try to make a high power amplifier. This amplifier consists of 2 channels (stereo). Each channel uses 5 pairs of end transistors (2SC5200 & 2SA1943).
In this assembly, I only used a 5A 47VAC transformer. But this amplifier can still be upgraded up to 10A 55VAC (if using the same box). The total budget for this amplifier is around $120.

Couple of observations: 1) Use masking tape to protect painted panel from accidental damage while drilling holes. 2) Use nyloc nuts to secure modules to the chassis. If nyloc nuts are not available use thread-lock blue - Loctite 242 to keep nuts from backing off 3) Always use a wire hook to connect a wire to eyelet :( Do not rely on solder to provide mechanical support.

[@dougieroberts7045]

Oh right, an amp that the fan sounds louder than the music, marvellous.

[@joshpoe]

You've never built a solid state amplifier that's obvious. People like you should start with a high voltage vacuum tube amp. Do zero research, maybe you won't live through it.

[@dougieroberts7045]

@@joshpoe Thanks for the advice, appreciated, I will save myself some money and buy something that sounds half decent instead.

[@joshpoe]

@@dougieroberts7045 before you judge maybe you should understand what speakers are being used and how this was recorded. I've listened to 1 million dollar Krell and Mark Levinson systems generating thousands of watts but for musicality I've been more blown away by analog systems running off batteries making less than 50 watts.

[@ConorNoakes]

That’s fairly average by PA amplifier standards…

[@Tremodua]

@@joshpoe This amplifier is not so powerful to run fans on idle or low load. My Yamaha amplifier turns on fans only on high load. And good amplifier has to have balanced inputs.

[@karmlan123]

OMG! The two loud cooling fans adds to the music.

[@willowsdmx]

ha, i saw what you did with the speakon, mounting holes where drilled in mirror, so you needed self tapping screws :) instead of the normal M3 bolts Nice work, would have chosen a heavier transformer though.

where did you get the amps from? can't find them anywhere .. would be nice if you included that information thanks

[@SylwerDragon]

Nice looking amp. I'm a bit worried about lack of protection. I didn't see any fuse on that transformer. Also there should be some inductance to remove noise from line. I also didn't see any fuse on other side of that transformer. But who knows maybe there was some. Anyway. I would suggest to add steel plate from both sides so actual amplifier is shielded from transformer .It might help a little to remove the hum/noise.

[@alexandrefournier-ahizoune8098]

the fuse is located in the ac connector socket @4:52

[@Daaremikkel]

There is a fuse on the power inlet. A noise filer would have been nice, but there is no switchmode stuff and a lot of capacity, so I am sure it is fine.

[@SylwerDragon]

@@Daaremikkel yes Sorry i did miss that. I'm glad for that also i'm glad for that second fuse on secondary. As you said some filtering would be nice and i'm not sure how effective it would be but i expect it will loose efficiency once higher power will come into play..but still it might be good idea to test it. Could you please make simple check ..Bring proper laboratory 6.5 digit meter and test AC voltage at the input of your power stage..I know you can't check all frequencies only line .but still this might show you how much AC you have in your amplifier..I would also suggest to check it with some load..lets say 400Hz on input with full power and then check it again..

[@expired56k]

@@SylwerDragon That and adding speaker protection would be a great idea especially given plenty of room inside the chassis. Overall, I think for the advertised budget it's a pretty solid build. Speaker protection would have only added maybe $10-15. At least in this build amp heatsinks are properly installed in line with fan airflow, seen so many in these DIY videos that are installed perpendicular to the airflow.

Nice build... But the amplifier looks underpowered with that transformer

[@jhabarretto9697]

Amazing. I had no clue 1 person could make an amp

[@AkkerKid]

This one person didn't make an amp. This one person assembled a few store-bought parts in nearly the worst, still usable configuration. This is a demonstration of what NOT to do. Instead, use the right sized components, don't run power, signal and output wiring anywhere near each other, add more fuses, etc...

[@dtwistrewind7361]

Great video 👍🏻 Back room amp, not a fan of fans in amplifiers.

[@whatevernamegoeshere3644]

Bro... Why did you zip tie audio, power and mains power cables together? That single step blew your insulation rating AND made it more sensitive to noise and interference. Also using black for earth? You took 4 premade components, put it in a box and screwed up the wiring. That was a 16 minute video. Nice.

[@AkkerKid]

None of the wires soldered went through the loops. No vibration mitigation on the solder joints. Fans blow back to front and are powered by wires parallel the audio signal. Eventual galvanic corrosion between steel and aluminum due to lack of isolation. Undersized transformer. No fuses beyond the C15 power jack. Binding posts are INPUTS?!!? I'm guessing this guy is FRESH out of school. Make a few PCBs and now you think you know everyhing.

[@AkkerKid]

@@dexcronicle9813 Sorry brother, I don't have need to build one of these. If you plan on building your own, keep in mind a few requirements. Keep high power and low power signals separate so you don't introduce noise. Make sure your weakest components are fuses so they break first before anything else. Consider gluing down large components like power capacitors so they don't break off of your PCBs.

[@stevesmyth4982]

Never rely on a soft soldered joint for mechanical strength. The holes in the transformer tabs are there for a reason, you're meant to hook a wire through each and make the joint so the end of the wire is evident. See 11:40 into the video for what I'm typing about. With the transformer connected as shown you'll get around +/- 21 V DC, hardly a high powered amplifier - maybe this is an advertisement for the PCB manufacturer that you get paid for.

[@wraiths_]

I know its been months, but I believe that is a particualr brand of transformer prevalent in Indonesia which has multiple outputs. Usually it has support for preamp 12-0-12 or 15-0-15 located at the bottom while on the other side has the higher output usually 28 to 55 volts

a powerful amplifier with a radiators located UNDER the amplifier boards, with no air inlets in the bottom of the housing; probably only for use WITHOUT the housing...?

[@jlinkels]

it is not very relevant. The amount of air blown by the fans is way larger than the amount of convected air. If it is a sound design when listening to low level music is a different issue. I don't believe in power cooling by default.
