  1. Dynalo Mini enclosure group buy

    Interested in TKD version!
  2. goldenreference low voltage power supply

    129x99mm Something like this: Gerbers, KiCad project, 3D view. Yes, finding the components in the library is sometimes difficult ).
  3. goldenreference low voltage power supply

    Thanks! Initially, I began making a scheme in Eagle CAD and it turned out to be very convenient. But when I started making the PCB layout, then rested in the restrictions of the free version of Eagle, and continued the layout in KiCad. In fact, the difference is small, especially if in KiCad enable the OpenGL mode. The interactive router in KiCad is a bit blunt, it needs a little more tips, but this is a very small drawback. For a new version of the PCB layout, I completely remade it from scratch in KiCad, and now I find KiCad very convenient. PS. Has slightly updated the project - added a fill of the bottom layer and added 10 ohm resistor for grounds separation.

    I remade my previous GRLV pcb for my amplifier: 1. Optimized the pcb size. 2. Fixed bugs of the previous version - added forgotten capacitors in the supply chain for op amps, the supply of all internal circuits takes from the pure part of the circuit, as in the original version of the board. 3. Now this is the native KiCad project, not the conversion from Eagle. Gerbers, KiCad project, 3D view
  5. goldenreference low voltage power supply

    I want to use GRLV for my new headphone amplifier. But I need 30V power supply with 3 sockets, and place for large capacitors in the filter (up to 35mm in diameter), and I want to use Elna Silmic II 220uf, 50V as output capacitors. And I spent two evenings to made my own GRLV pcb, simultaneously learning kicad. This is the first pcb in my life, which I have made myself. I also replaced the diode bridges with the fast diodes MUR820, and shunted them with ceramic capacitors. Perhaps someone will find this useful. But I'm not sure of the complete absence of errors ).

    Can I use opa445 instead of opa134 for GRLV for 30V output? It's necessary? Thanks!
  7. KG Balanced Dynahi build discussion thread

    Where can I find gerber for lsk489/lsj689 pcb? Thanks!
  8. goldenreference low voltage power supply

    Can I simply replace the tantalum capacitors with electrolytic capacitors? For example, the Nichicon KL series.
  9. The Multi Amp aka Dynalo Mk2

    Thank you! I hope that this is indeed so, not my mistake. Thanks a lot! Heatsinks from the nearest radio parts store, noname ). I bought a pot on ebay. I found a seller with a similar product and asked him to order from the manufacturer for me. It took 3 months but I got what I ordered.

    In sockets
  11. The Multi Amp aka Dynalo Mk2

    20v psu , 1.60v on the led's
  12. The Multi Amp aka Dynalo Mk2

    Thanks! 65-70°C on that340, both. But works fine. Now I checked all the components of the strapping - it's all right. But hot.
  13. The Multi Amp aka Dynalo Mk2

    I assembled dynalo mini and that340 chips on my board is very hot. Is it normal? Thanks!
