    TPA3118 60W Power Amp Module

    Ok, so it's enough keep the volume under 3/4 if I'll use a 19v PSU. Maybe I could try to build a 12v regulator circuit, just to to build it and see how the TPA3118 will sound with the smaller speakers. I have to wait to make some money to order the amp and the PSU.

    TPA3118 60W Power Amp Module

    My only 9v PSU is an old Boss red label, but it's only 300mA. Is the TPA3118 max current draw 50mA? I'm not sure. To get 12v I should use extra circuits or I have to buy a 12v PSU, but in this case I prefer to buy a 19v laptop PSU. I prefer higher wattage to benefit better the amp. My speakers...

    TPA3118 60W Power Amp Module

    Is the 7809 was hot? Maybe it need an heatsink at higher voltage? Not sure, but... what about the current consumption? At 24v you need too much ampere for the 7809?

    PSU for TPA3118 Power Amp

    I hope I'll not have noise issue with a PSU I'll buy then.

    PSU for TPA3118 Power Amp

    I'm searching a laptop PSU to buy, at least 19v and 3A, I'm not sure if I have to use 24v, because that is close to the limit for the TPA3118. Do you have a brand or model in particular. Did you have pictures of your PSU used with this kind of power amp?

    PSU for TPA3118 Power Amp

    Your built it's very nice. I prefer to use the smaller 60w version, but... you used a battery? I think a PSU it will be ok for me.

    PSU for TPA3118 Power Amp

    These are the PCB board I can find: https://www.ebay.it/itm/154122973822 https://www.op-electronics.com/it/amplification/679-tpa3118-mono-power-amp.html Amazon or AliExpress, too. There are a lot of of these blue board, I think those are all the same board. It's very simple: One Input, One...

    PSU for TPA3118 Power Amp

    I still have to buy the TPA3118 PCB, and the PSU. But if that's enough to solve noise issue I have a pair of big 4700uF. So, in case I could add a sort of noise filter with a 1N5817 in line, a big electrolytic cap and maybe a smaller ceramic cap. By the way, I'll buy, I have to decide where...

    PSU for TPA3118 Power Amp

    A laptop one fore sure, I'm afraid to buy one and found it noisy, I wrote it everywhere. :D I got some suggestion, but I can't to buy exactly the same model in the shop available in my Country.

    PSU for TPA3118 Power Amp

    I want to bump this my topic (that I forgot) because this year I would like to buy a TPA3118, but I afraid to buy any PSU. So, if the PSU you used work fine without any noise or issue and I can buy it on amazon or ebay in EU, I'll be glad if you suggest the model. Thanks!

    TPA3118 60W Power Amp Module

    Thanks for your reply. I have two question: one about the speaker, seen the higher wattage I could get with this amp than my 1w - 2w amps I built until now; and another one about a good and right PSU to use with it, being laptop PSU are not made for audio application, though volts and amperes...

    TPA3118 60W Power Amp Module

    But, if I supply the TPA3118 at 18v (and that could be even something more) it should be over 15w output power, isn't it? I thought it was a problem for the 15w speaker. I want to be very careful with it, because the speaker it's very low cost and the cabinet it's just a wood box I found. If I...

    TPA3118 60W Power Amp Module

    The newx year I want to buy a TPA3118. I looked at that for a long time. To make it sounds good and reasonably loud I hoped it was enough put in front of it a kind of preamp like Dr. Boogie or Tight Metal, or something less distorted like a Guv'Nor or a Bluesbreaker. And of course a clean preamp...

    Are You Breadboard Baking Yet?

    On my breadboard there's today a TBA820M amp, schematic from the datasheet. There are two kind of schematic: one with the voltage on the speaker and one with the ground on the speaker. I tried the one with the voltage on the speaker. It sounds, but I have to talk about a weird things. Usually...

    Tayda Shipping

    Thailand Post delivery is available in my EU country, now. My cart is around 0.53 kg, about 54 $ of material and almost 21 $ Thailand Post delivery. Probably I'll add something else. No DHL, so I should pay just the VAT because in Italy under 150 € I have to pay just the VAT. Should I expect...

    Tayda Electronics - shipping

    If we will pay a charge of just 25% I think Tayda could be still competitive. Of course today we pay more than the past, but a lot of stuff on Tayda costs even 50% less than other shops. Maybe with film box caps or some IC we save just a few of cents, so we don't save money buying that stuff...

    Do you remember the weight of the package (in the Tayda's cart is indicated)? Or the dimension of the package? Box of bag? Maybe all this thing are important to calculate the fee. Anyway, I think you're said right, Temol, my math early was wrong because I thought it was 30 $ in total, instead...

    Tayda Electronics - shipping

    OK. I need some math (and French lesson :unsure:). The total to pay is 25,50 € (about 28$). 25,50 € = 17,50 + 8. But how we can calculate these number? What's 2,92 €? PS The description (potentiometers, diodes, inductors) it's because the package it's been open up and check up? Maybe to control...

    Friendly Fire Fuzz bass mod?

    If you want to add taht one band parametric circuit you can do it, and with it you can boost and cut a certain range variable frequency. I can suggest you to change the C6 with a 4.7nF to get a basic sound with a more flat mid, then use the one band parametric eq to shape the sound, but I can't...
