    Source selector switches

    Quote: - but are you sure about the quoted part? there's enough ways to wire an attenuator that i'm easily confused. let's dive into my confusion. put it in the direct signal path as you say. it has various steps of resistance. the least produces the most sound, and the most the...

    Source selector switches

    is there a trick in the question that i'm missing? you'd want non-shorting, otherwise you'd be feeding in two sources at once, briefly. shorting would be for a stepped attenuator so you don't briefly have zero resistance and thus full gain.

    Are there any DIY kits available besides...

    sygyzy, take their advice and figure out how to assemble your own parts list and order parts from digikey and mouser and suchlike. it's definitely intimidating at first, but it's a skill you likely want to learn because you'll likely want to build more amps. i highly recommend the cmoy. it's...

    Hardware Suggestions?

    hey was?, since nobody came up with part #s i just had a look at the digi catalogue to see if could simplify things for you. first thing is that digi sells this stuff in 100's. i suggest you try your local hardware for M3 nuts & bolts & washers & standoffs. even in my little town you can buy...

    Advice for noob

    if you're completely new, start with the cmoy. it does sound good, and it's a much better place to make your first mistakes. (and mistakes are just part of learning.) gsferrari, i believe the meta42 is discontinued in favor of the pimeta. mainly because the buffers are now unavailable. can...

    Enclosure Types

    Quote: Originally posted by JohnFerrier I've wondered how easy mu metal is to cut, drill holes in, and possibly bend. I noticed in the link you provided that it indicates that mu metal is worked like stainless steel. I'd like to know if that means that it is hard for a DIY'er to use...

    The great project: amp for electric violin. Help!

    no offense to the crew here, but i wonder if you might do better to try any of several active guitar amp forums on the net. one of those might even be able to hook you up with other people doing violin amps. and it'd be pretty fun to plug a violin into a big ol' Fender.

    Why the META42 Shape?

    META just built...strange problems

    stereth, a meta42 is a pcb from tangent, not an amplifier topology. nobody is trying to give you the gears here, it's just helpful to establish that to be sure what you're describing. unfortunately, 'meta42' is a common misnomer for the circuit the pcb has made popular, so there's some...

    Suggested Sticky - Source DC Component

    thanks, tangent & jeffreyj. jeffreyj: the wm-af54 is a tape walkman, hence it's 'play' or 'off'. just tested again with no tape and got 0mV, both at play and off. then played a tape and got the slow descent again afterwards, on play without tape, and off, starting at over 600mV this time...

    Meta

    gino, a lot will depend on your system. a linkwitz will not create a soundstage for a system that does not already have one, but it will improve the imaging that is there. it's very difficult to describe without using subjective terms. it's a subtle effect, but a very good one. as others...

    answer: yes. i trust you're doing the reading and are just checking back here for encouragement and clarity. simple summary: it cuts down on headphone fatigue. y'know how you can only listen on cans for so long? this takes care of that. recordings are generally made for playback on two...
