LM1875 audio amplifier kit assembled far from home 

Really?

@@AniketBasak a heatsink I am will to pay for.

@@keithblume5159 Oh, well where I live we get pretty good heatsinks, maybe you could try aliexpress or something?

So would I but the mosquitos would eat me alive.

I've lived in a rural area my entire life and in one particular location since I was 6 years old. It's nice except that there are no services whatsoever and thus no broadband Internet. I'm *still* paying for a dial-up connection (yep) for my father, though I have, thankfully, found a single location in my home where I can *barely* get a single Verizon LTE tower. I use a phone hotspot for Internet. I've stayed in urban and suburban areas on numerous occasions, but can never sleep :(. I'm sure that you get used to the noise and lights, but I'll never willingly live in a populated area. However, as people drive more and more, people from town now constantly come out here to party and drive their trucks and ATV's on private property without permission. Over the past 2 decades, it's become a nightmare and we often have people banging on our door at 3AM drunk out of their minds and wanting us to pull them out of the mud or to use our phone because there's no cell service here. We've had 2 car fires and at least 3 vehicles driven into flood water in freezing weather such that the wet, muddy occupants had to shelter in my living room until help arrived. The point is that living in a rural area was once a reasonable tradeoff where you exchanged services and nearby shopping for peace and quiet, but today there is no more peace and quiet; idiot townspeople in trucks and ATV's simply ruin everything and they have *zero* respect for anyone living here. With 4X4 machines, they will even find you miles away from paved roads regardless of how many No Trespassing signs they pass. They seem to believe that they own everything. We occasionally even have people running *chainsaws* at 2-4AM. I grew in a very hospitable family that helped everyone that we could, but we are now so sick of liars claiming that they were "just turning around" while their vehicle is 200 yards off the road in a mud pit that we now hate everyone :(. Nearly every single person that has ever asked for help has lied to us and stolen whatever we let them borrow. We even had one car beg us for a chain to use and then hold their middle finger out their window as they drove back past with the chain now theirs. After losing 4 chains and a come-a-long this way, we no longer loan anything to anyone. I grew up thinking that most people were nice, but the last 20 years have taught me that most people are worthless, selfish criminals and I resent them for ruining my worldview. I no longer believe anything anyone tells me, as most people today simply think it's entirely normal to lie. There's nothing I hate more than a lying thief, yet we're now surrounded by them out here. So, be warned that living in the countryside doesn't keep the morons away, as they'll simply drive out from the cities and towns in their loud off-road machines to harass and rob you, even while telling you to your face that people living out here should not expect to have "modern" services like phone or Internet. I'm not making that up, as multiple people have told me that and one of them was asking to use my landline phone when he said it! 2 others were AT&T technicians (!!), though they seem to thankfully be retired as the ones I meet now are quite friendly and would like to help us more if only the company would let them. Oh, and our "landline" is a temporary cable that runs in the ditch beside the road for about a mile before connecting to a pole and AT&T has no plans to ever fix it *or* to build a cell tower here, so they're just hoping that we'll die soon. The state regulators even changed the rules so that telephone companies are no longer required to provide landline service :(. Our services are *worse* than they were 30 years ago. So, no services, but no peace and quiet, either. If you live in a town or city, don't romanticize the countryside; it's rapidly being destroyed by awful people from the cities and their toys. I'm sure that all modern American aren't bad, but the ones we "meet" out here don't deserve the air that they breathe :(. Selfishness reigns supreme.

@@JohnAudioTech Depends on where you are, as the mosquitoes are much worse in the nearest town than where I live in the country. Perhaps the bats or other creatures here help keep them under control, but it's usually not bad and a couple squirts of DEET will work miracles with ticks and mosquitos. Ticks have gotten *much* worse in recent years, however, as 2 new species have shown up thanks to the warming climate and they are both smaller (harder to notice) and carry Lyme disease, whereas the resident species did not. I have to worry a lot more about ticks than mosquitoes.

Yes, they will need a preamplifier.

Love your vids btw. Forgot to mention 😂

Power output is supply voltage dependent. With a +/- 25 volt supply you can get ~30 clean watts from this kit at 8 Ohms. For 50w, you need to move up to a more powerful IC, such as the LM3886.

Some older circuits (1960s) used germanium transistors and used positive ground chassis. Positive ground chassis with negative grounded capacitors doesn't make any sense.

I have used the exact same transformer from RS in one of my amplifier projects. It works fine.

All of those "LM1875" on chinese boards are fake, if you go by TI's own specs. There are articles about it online.

@@DasAntiNaziBroetchen what should be the heatsink size (length and width) for single Tda2030A Ic if it has to deliver 10 watts@4 ohms load on 12-0-12 V transformer ? I want to make a 4 channel sound system with 4 such chips so I want to know the heatsink size for single Ic so I can cut out a single large heatsink for all 4 Ics. I searched this online but got confused answers and also the datasheet I don't understand as it says something about thermal resistance. So please tell me

IT'S a good thing tho 🤣

@@KuntalGhosh unless u turn it up too much and it gets smelly.

He died back in July. I made a post about it on my community page.

Sorry but it's a platonic friendship.

If you train them to wear a harness and lead, you can walk them like a dog although they don't go as far.

@@JohnAudioTech Thanks. BTW, sorry for the typo. I meant "leash".

In Canada (Manitoba), they are licensed, kept on owners property, if not then exercised on a leash ( like Dogs). Result : no foul urine smell in public places, no crap in neighboring gardens, no fighting/ screaming noises through the night! , no killing of wildlife birds. Unlike in England, glad I left .

@@anglosaxon1622 I've heard that mosquitoes are the size of vultures in Manitoba and are the provincial bird? Is that right? :-) Here is Ontario the black flies are probably the most pesky at least for a few weeks of the year. Cheers!

@@CommenterRick :) fortunately not true😂. Coincidentally visiting ON, are the black flies disguised as black squirrels ? ;)
