    TDA7266M is a bridge amplifier, so its negative output (pin 2, OUT 1- ) cannot be shorted to ground.The output socket must be isolated from the metal housing.

    • @erikvincent5846
      @erikvincent5846 4 роки тому +2

      This is correct. This is why in the build doc, it specifically states that the output jack must be isolated (usually plastic) so it doesn't ground out with the chassis. The big tab on the TDA7266M on the other hand, that would benefit greatly by grounding it to the chassis. Not just for the sake of grounding, but also for the sake of being a heat sink.

    • @erikvincent5846
      @erikvincent5846 4 роки тому +5

      Hi Sangr, basically the 2 things you'd be looking at are C1 and to a lesser extent, C3. C1 is the input filter. The larger the value, the more bass frequencies it will let in, but it also will make the sound be a bit darker because of it. For a bass, this may be desired as the larger bass frequencies may outweigh the darkness of the tone. So, going from a 10nF cap to a 100nF or larger may be advised. C3 is just a general power capacitor, but when dealing with class A-B amplifiers that are solid state, it needs larger capacitance to handle slugging low frequencies. That's why Woofer circuits tend to have some large caps in them. 220uF should be sufficient, but a woofer circuit I saw using the same TDA7266M chip did use 470uF capacitors instead, but was probably doing it to handle those sub-bass frequencies.

    Hi! Hopefully you see this and can offer some advice.
    I received the kit, wired it up, plug it into my Marshall 1x12, turn on the power switch, LED lights up, but no sound. I turn the volume knob halfway, nothing. All the way, nothing.
    I took measurements with my voltage meter and get no voltage on any of the three points in the pot. I get readings on all the caps and resistors. And I get readings on some but not all points on the op amp.
    What am I missing? I've checked all of my solder points and they look good.

  • @MikeFredensborg
    @MikeFredensborg 4 роки тому +1

    Have a few questions.
    1. Can I series two sets of paralleled 9 volts batteries into 18 volt, and how many batteries would that require to run this amp, for say 4h of jamming at 50% volume on this little amp?
    2. I have some small speakers from an old surround sound system, 15 watts, but 4 ohm. I have 4 of those, will this amp be okay to drive 4x4ohm series wired speakers (16ohm "aproximately")?
    3. If #2 wont work, can I just series 2 of those speakers to hit approx. 8ohm, would that work?
    4. Is it a possibility to run two amps into those speakers at the same time to get some "headroom" to drive the speakers without burning amp or speakers?
    4a. If #4 is even possible, can I solder just one volume pot to both amps, so they they are like "matched" in output? -and would this require another value pot?
    5. If I push the input a little with a tube OD pedal turned up a bit extra, does that change any of the above answers, or is this a bad idea to begin with?

    • @erikvincent5846
      @erikvincent5846 4 роки тому +1

      As of the batteries, that's a hard to gauge question. The amount of current consumption varies drastically depending on what you are playing through it. If playing quiet single notes on the higher frets, for example, it may consume little current. Chugging hard on a palm muted E5 chord will consume a lot more. Putting an OD before the amp will drive it harder and therefore consume more current. Even the volume knob position plays a role. All these variables will effect the battery life. As of speakers, so long as you get 8-ohms of impedance, you should be good. Just make sure your wire lengths don't create an "out of phase" issue. I wouldn't recommend two amps into one speaker.

    I just had another thought: can i put my 12V 1amp dc power supply in an input and instead of just one +and one - cable i put 2 on each side
    Will that give me 2x 12V with 0,5ampere or am i completly wrong
    It's just becouse of some reasons i want to build my own power supply and i'm not that good at this and more put some things together

    • @erikvincent5846
      @erikvincent5846 3 роки тому

      So, the power rating for this will accept 15V. It draws a bit of current, especially when you push it with something, like a large boost, but 420mA should be able to work with most speakers you'd likely be pushing.
      As of your power supply, the 12V 1A delivery is likely limited by the electronics inside and not your wiring. So, splitting up your wiring will not "divide" your current. As of "+" and "-", one is your negative wire, or ground, and the other is "hot" or 12V. Both wires will be needed to deliver power somewhere.

    I'm a beginner, and I'm trying to build this amp from the parts list and schematic but I'm having a bit of difficulty. I'm hoping I can get a bit of help from the veteran pedalsmiths out there. I'm starting with a breadboard before I commit it to soldering, but there are a couple of spots in the schematic that puzzle me.
    First, there are no (-) connections for power or signal input. I'm assuming that in the kit these are provided by grounding the jacks to the enclosure, correct? If so, should I be able to connect the negative side of the power and signal-in jacks to common ground on the breadboard? If that's the case, are there any other spots where the grounding is not explicit?
    Second, I don't understand the notation "3*2" at the VCC connector on the TDA7226M. The datasheet for the IC says that pins 3 and 13 are both VCC. What connection(s) am I supposed to make here? 3 and 13?
    Forgive me if I'm overlooking something obvious. As I said, I'm just getting into the hobby, and this is my first build. I'm eager to get it working. Thanks for any assistance you can offer. Cheers!

    • @erikvincent5846
      @erikvincent5846 4 роки тому +3

      No worries. Your input power ground just goes to common ground, along with the input jack's sleeve. Do not connect the output jack sleeve to ground. That will kill the signal. The 3*2 is an EAGLE Cad artifact. You are correct, though, pins 3 and 13 go to positive voltage.

    • @erikvincent5846
      @erikvincent5846 4 роки тому +2

      Hi Alex, it would have to be an off board, but the idea would be to inject a tone control between the input guitar jack and where the input guitar jack connects to on the PCB. So basically, your tone-control circuit goes in between the guitar in and PCB. Lastly, you will need to provide a common ground to it. A simple way, would be to wire it like a tone knob from a guitar. The only limitations you would have, really, is the size of the enclosure. Like you couldn't inject a Rock Bottom PCB into it unless enclosure was big enough to house both PCBs.

No additional resistors or anything like that to add a load. A warning though, it will be loud, so you will most likely want to turn the volume down.

      The more volts, the more headroom, which would result in less likelihood of clipping and distorting. So 16 to 18V power supplies will give you that. Speakers, I could go all day on. I got a Harley Benton 2x12 with Celestion Vintage 30s from Thomann and it rocks. Just get a good cabinet, and that will be it.

    • @thomasdahlgren1985
      @thomasdahlgren1985 4 роки тому +2

      As Erik said, to get the most clean headroom you want to run the power supply at the highest voltage that the power amp IC is rated for. In this case that appears to be 18 vdc. Alternately you could search for a replacement IC rated for higher voltage and then beef up the power supply. But the higher the power the greater the cost (and the more the need for a heat sink/cooling system.) Realistically speaking, these are solid state watts, so even going to 24+ vdc is not going to get you a whole lot of added volume.

    Hi Paul & Erik, I just finished building this and cannot get any output using my guitar which is equipped with active EMG pickups. If I use a guitar with passive pickups I get sound, although it is very low output. The EMG guitar works with my other amps.
    Do you know what might be the cause of this?
    Edit: I’ve been going over the build to check everything is wired correctly, and when using the multimeter in continuity mode, the input jack tip is registering as being connected to ground (this is obviously the issue), but I have no solder bridges, and everything is wired correctly.
    Not sure where to go from here.

    • @erikvincent5846
      @erikvincent5846 4 роки тому +2

      If you are certain there are no solder bridges nor and bad wiring, you may have a bad component. I'd check the following
      1. The volume pot. The volume pot connects the input tip to pin 1 of the pot, while pin 3 of the pot is ground. If internally, that is broke, it may shunt to ground
      2. The D1 diode is on upside-down or is on right-side-up, but is dead (internally shunted). When diodes "die" half the time, they blow apart, but the other half of the time, they fuse together and become a near 0 ohm resistor, which in turn shunts to ground.
      3. C2, C3, and or C4 are damaged internally. I see this more with box film caps more than any other. Basically, the internals are touching leads, which turns the capacitor into a resistor. If a capacitor not in any board shows a low value of resistance between its two leads with a multimeter, that capacitor is probably not good and will ultimately shunt something (in this case, to ground)

      You could use two TDA7266M ICs but you would probably want to buffer (copy) the input and feed the original signal to one TDA7266M (left) and the copy to the other TDA7266M (right). I would look into using something like the TDA2009A instead, which was designed for stereo (input and output).

      Only temporarily. The TDA7266M has for a maximum voltage rating of 18V on its datasheet. Now in a lot of cases these companies, when writing the datasheet, are aware that some of their chips may perform at a slightly higher rate on some of these specs, but not all of them will. So, they will guarantee the lowest value that will work on ALL the chips manufactured, which would be 18V. Some chips may work at 19V. Some may work at 19V for about a week and then die. As that spec is above the manufacturers recommendations, we cannot guarantee what it will do.

No additional resistors or anything like that to add a load. A warning though, it will be loud, so you will most likely want to turn the volume down.

However, the current draw is reflective of that. One difference with the output of a pedal and the output of a power amplifier is the two wires on the output jack. On a pedal, typically, it's signal and ground. On an amplifier it's signal+ and signal-, not ground. Another difference, as indicated earlier, is the current. Cabinets go into the realm of 100mA and above, while pedal's (not how much current is uses to derive a signal, but how much it pushes out) is tiny. A pedal cannot deliver the power to drive the speakers, whereas a power amplifier can.
