    Power amplifiers that are good for headphones - how are they built?

    It ultimately comes down to components used and the circuit design (electrical and physical layout). Is that what you're asking?

    Portable amp for Ety ER-6i...need more bass

    Hey guys and gals, I bought the ER-6i's a couple of months ago and really like them, but I would like a little more bottom end. What amp do you suggest with a decent sounding bass boost? I'm shooting for no more than $150 here so I'm thinking the iBasso T2 (I really like the size too) or the...

    Custom Transformer for the KGSS

    Check out Renco Renco Electronics, Inc. They have decent prices on small batches and prototypes. Not sure what they would do for personal (not company) orders.

    What happens if you leave your iPod running without headphones plugged in?

    Why would it be damaged??? Does it work? It sounds like the play button got pushed accidently about 3xx songs ago. With or without headphones plugged in it's going to just play. Use the hold switch. Side note...if you have headphones plugged in and it's playing, it will pause (and...

    MDF cutting guide/app?

    Did you enter the tuned frequency? If so, why did you go for 19.33Hz? Seems kind of low. It looks like the actual will be around 50, which seems a little high. I think optimal would be around 35, 37 ish. my $0.02.

    ipod lineout with an attenuator

    The lineout of the iPod is not intended to drive headphones. It doesn't have the current capability to drive them. You may get away with it for a little while, but you could potentially harm the DAC (or whatever is actually the driver). If you're not using an amp just use the headphone output.

    Pushing the envelope with PCB height... using thin insulating material?

    Static electricity and butyl rubber are friends too Stick with the teflon or Nomex (if you can find it). The fragility of Teflon really shouldn't be an issue, it's going into the amp, and that's it...shouldn't be touched again.

    Should transformers buz/hum?

    Yeah, just put the two leads in the two slots on the recepticle and check the AC voltage.

    Post pics of your builds....

    Looks like a good start tharenth! I agree with Eokboy...also you could go with a rocker switch instead of the toggle switch in the front. IMO they don't look too clean and takes away from it. Good luck and welcome!

    Should transformers buz/hum?

    I highly doubt DC on the utility line, but I agree with a higher line voltage. The transformers in these components [I]should[I] be able to take 125VAC or so, but they are probably still nearing the saturation curve of the core.
