      @@TonyBursey i repaired my Fender FM212R guitar amp. Replace some caps a componet that attaches to the heat sync. I'm very scared to plug it in to my wall socket and trip the main breaker to my home and or get shocked. What is the safest way to do that ? I read somewhere the i should use a isolation chamber or a variak. Are they a safe way to power up the amp with out these concerns ?

    Super helpful! I've got a Frontman 25R, which is very similar, but it uses a TDA1514a chip instead. Do you have any tips for testing if that chip is shot the way you have for the 2050?

    • @TonyBursey
      @TonyBursey  8 месяцев назад

      Thanks for the question. I did a quick search and found a data sheet electro-dan.co.uk/Electronics/TDA1514A.pdf. With the 2050, the ground pin should not have continuity with any other pin otherwise it was bad. I would think that would also be the case with this chip. Hope it helps.

  • @caponokap706
    @caponokap706 3 года назад +1

    Sir, my amp turns on but when I plug it on my guitar, doesn't reproduce any guitar sound, just buzzes, what could be wrong? The amp or the input jack? If it is the amp, what issue could it have?

    • @TonyBursey
      @TonyBursey  3 года назад +1

      Thanks for the question. Without seeing the amp, it is hard to say. If the amp is still on and there is no sound, it could be the input jack or it could also be the output to the speaker. It could also be a dirty volume pot. Do you get a crackle sound when you turn the volume knob back and forth or tap on it? If so it could just be dirty, in which you can get yourself some electrical contact cleaner. With the amp off, you would need to take out the chassis and spray the pots and then turn them all the way in each direction many times until they turn smooth and easy. You should also check all the solder connections while the board is out, especially on the input jack. I had to resolder my input jack connections on the board since they were cracked. Hope this helps.

    Hi, I have a fender 25B
    The amplifier chip is burned, I need to replace it, but I'm not sure where I find the right replace part, can you help me?

    • @TonyBursey
      @TonyBursey  3 года назад

      Thanks for the question. I would first suggest that you get a schematic for your amp. You can download a PDF for the 25B from here: www.schematicsunlimited.com/f/fender/fender-frontman-25b-bass-amplifier-schematic. If you are sure it is the amp chip, this amp uses a TDA1514A chip. Depending on where you are, Amazon and eBay have listings. Hope this helps.

    Hey Tony! My 15G has jumpy volume when I use normal volume knob, the stronger I strum the louder the attack is, while less loud notes are barely heard. I might've left an amp in a cold place for winter. What could be an issue and how to fix it?

    • @TonyBursey

      I have been thinking about this for almost a week trying to find out what might be causing this and have not been able to find anything. The first thing I thought of was dirty pots but that would not explain the soft notes. Would not hurt to try cleaning the pots and the input jack with some electrical contact cleaner.

      Thanks for the question. You can use either a thin screwdriver or a sprial nail and put into one of the screw holes on the back to pry the back off. Mine was stuck pretty good but using a screw driver was better because of the handle... more to grip than the nail.

    TONY BURSEY,
    if you remove the Choke in the power supply what does this do to the AC ripple?
    can this add harmonics and modulate the power tubes from the AC ripple signal?

    • @TonyBursey
      @TonyBursey  4 года назад

      Thanks for your question. This is a solid state amp and does not use tubes at all. Although I have not yet owned a tube amp, from what I have seen, you would not want to modulate the power going to tubes. They need to be biased properly in order to function, otherwise you will run the risk of burning them up.

    • @TonyBursey
      @TonyBursey  4 года назад +1

      Thanks for the question. I have not had that happen, but you may want to start with the input jack or the speak connections both at the speaker and the board. Look for cracked solder connections. Obviously difficult to diagnose without actually seeing and testing.

      Just to add a little more. I noticed that when I tapped on the red & white aux jacks that is what the buzz would more so start/stop. I have the board out now and there’s no cracked solder joints but the white port is sort of free floating and rattling inside.

    • @TonyBursey
      @TonyBursey  4 года назад

      Thanks for your comments. Sounds like you have found your issue. One thing I have heard is that using the aux ports with a device while plugged in to an outlet could cause the TDA 2050 amp chip to short out because of grounding getting crossed. I don't use the aux inputs but this is good info if mine starts to develop a hum.

    • @TonyBursey
      @TonyBursey  5 лет назад +1

      Brian Torres thanks for the question. Yes it is. The PCB already has all the printed circuits in place. Fender used the same PCB for both the 15G and 15R. The reverb components just need to be soldered in. The front face of the chassis also already has the hole for the reverb pot. The 15G sticker on the front is put on right over but it would be easy to punch a hole in.
      I have been debating for a while whether or not to do it. I would have to pick up all the components so I don’t think it would be worth it really. Might cost less to pick up a used 15R.
      It would be a good project though.
      I have the schematic for the 15R somewhere with the list of components.

      The first thing to check with the amp unplugged is the fuse. If the fuse is blown, first check that the fuse is the correct one. The type of fuse is printed right on the circuit board. The fuse should have the type stamped into one of the ends. Get a few replacements of the same type and try a new one.

    The main amplifier IC, TDA2050 is a discontinued item now. But, still available on online auction sites. You checked the main transformer and declared the power supply was OK.
