    Different sound tuning for different markets / continents for the same product?

    I just saw this old video and I just think it's wrong on so many levels. If this is a marketing video, it's very bad. NO ESD grounding, opening it on the carpet and not the right soldering tip. Also, what if I want the ORIGINAL sound? Not to mention all these will MEASURE differently. And...

    Headphone amp kit for complete novice?

    Hi all, I’d like to build a simple headphone amp from kit or instructions, and I have absolutely no experience. What would you recommend as a good starter kit that includes casework? I’m thinking one that works from a commercially available wall wart, so I’m not building a power supply first...

    ZOTL40 Mk II Tube Amp Review -- New Approach

    This is interesting for the idea of using a HF carrier to reduce the transformer size. Not really new, actually very old, but I have not seen it applied to an audio tube amp in many years. Otherwise it seems a fairly average tube amplifier. And of course the reviewer takes a healthy swipe at...
