    Iron Pumpkin(s)

    After successful realization of concept , I knew that few shortcomings of Iron Pre aren’t in necessity for Preputium made of parts , or Iron choice …… it is in fact of still having resistive attenuator …. and always tempting fact that somehow is possible to dispense scarce Toshibas for something you really can buy in nest Tobacco Store. So ,as a result of my day(night)dreaming, it came to prototyping of Iron Pumpkin , both SE and Bal iteration . Last one simply without suffix, while former obviously having SE as part of name. Due to intrinsic nature of balanced xformer ( fed ballanced , outputting signal also ballanced ) with necessary involvement of GND on either or both sides , it’s also having virtues of SUSY , as Papa patented it years ago. (Old Bull/Devil , always tongue in cheeks ). So , conclusion – to my ears – inductive attenuator is best sounding of all alternatives , and I really succeeded in dream of achieving (settable) gain with same device and , last but not least , natural conversion of SE to Bal , or other way around , in case of Iron Pumpkin (Bal) .

    Pojacalo za Magneplanare

    I jos jedna netacna informacija koju plasiras je da impedansa zavisi od potenciometra. Ne impedansa je unutrasnja otpornost generatora (sklopa) koji je ispred potencioetra, a potenciometar je opterecenje tog generatora... Ako je premala vrednost pota u odnosu na Rgen generator ce imati malo opterecenje na izlazu pa nece moci pogoniti uspesno sklopove koji slede.

    Ma kakav prilozeni link - posmatraj iz ugla zdrave logike Sto je veca vrednost potenciometra to je veci R serijski sa paralelnim kapacitivnim opterecenjem. Kada jer BILO KOJI pot pri 0 skoro sva njegova vrednost je cinioc RC konstante... Max vrednost pota se i IZRACUNAVA na osnovu podatka o narednim kapacitivnostima da bi se postigla zelejna granica opsega. Proveri i u bilo kom simulatoru, i videces da je tacno ovo sto sam napisao. Ustvari prepisao iz manuala clanaka i udzbenika... I nemojte da saljete i da pisete elementarne gluposti i da o netacnim stvarima razglabate, do u besvest...

  12. I kako prosao danasnji brm-brm dan ? eve kako meni bilo : Vreme sugavo , kisa stane pa pocne od jutros skontam utanjilo se u kuci sa filter kahvom, a ja ovisnik ; gledim ceznjivo napolje da skontam kad ce shower da prekine bar na malo , da mogu da idem sa (bilo koja ) dva tocka umesto cetiri prestade , ja jedva docekah ...... ogrnem tanku jaknicu i turim kacigicu (za lokal) na glavu , odzujim do prve prodavnice ..... "tvoja kahva stize u utorak , sad nema!" odzujim do druge prodavnice istog lokalnog koncerna .......... same story izadjem iz prodavnice ..... kontam - isti lokalni koncern ima prodavnicu u seocetu 7km dalje ....... odzujim tamo , mmcu mu hladnjikavo u jaknici i kacigici sa 80 ....... tamo nema kahve moje izadjem iz prodavnice ..... kontam - isti lokalni koncern ima prodavnicu u sledecem seocetu 10km dalje ....... odzujim tamo , mmcu mu hladnjikavo u jaknici i kacigici sa 80 ....... tamo nema kahve moje izadjem iz prodavnice , krenu kapi kisice ......... 17km do kuce a ja u jaknici i kacigici zuj ..... 80....90.....100..... zuj stignem kuci , skinem kacigicu i jaknicu , obucem dzemper i skuvam crnu kavu

    Iron Pumpkin(s)

    so , schmtcs are here both Pumpkins ( meaning - what's on electronic pcbs ) are completely compatible to be used as (still MIA) Iron Pre , not yet visible in DiyA Store so , selector - pot - buffer - autoformer ( be it everything SE or Bal) is good and certainly cheaper way , even if definitely few notches down. schematics are proven , so there is one (little more complicated ) possible substitution for Toshiba/LS approach. feel free to try it , on protoboard or PtP , your choice how it sounds ? well - foot-tapping , music is there ..... no thoughts about spectrum dividing , music is simply there and - I'm not responsible for that ( even if Genius) ..... that's simply nature of Good Iron ....... remember M2, F6 , Ultrasimple BAF Sony amp ?

    Iron Pumpkin(s)

    Anyway , what was main quality of (then) newly explored territory for Mighty ZM …. I couldn’t easy describe what that was , and only after few years I came with explanation how I understood it – what I was hearing ( and I hear that even after all these years) is result of important phenomena – Signal Energy Preservation. Simple – with resistive loading – efficiency of stage is always low , while with inductive loading it is way higher …… energy of signal isn’t dissipated along the chain (as with resistor) , it is being transformed in ratio of intrinsic values (voltage , current , thus impedance). Remember that I’m not formally educated in electronics , so I’m pretty much free to invent new postulates whenever I want . During the years , having direct contact with plenty of pro gear (in radio production), I started noticing signal iron in plenty of positions , my Guru discover to me how versatile can be all sorts of so called repeater coils , scavenged from old telephone equipment … To cut (some , not all ) story short – I started collecting all sorts of signal Iron , thinking how one day I should/could/would use them in something ( that behavior is , I believe , familiar to every Greedy Boy around). Besides my (very successful) experiments with xformers as main DAC I/V conversion elements , especially when used fully differential ,and numerous more or less successful attempts to include Iron everywhere in audio chain , I was (not worthy) given by pair of (so called basic ) Intact Audio 200$ AVCs; my own personal German ( known around as Golden Ear-ed Generg ) sent them as Geschenk . They’re ( realized as basic passive box) pretty good sounding , combined with papa’s Koan M2 : AVC & Input Selector for Papa’s Koan M2 ; temporary case ? | Zen Mod Blog So , What is Gain structure > What is Gain Structure? , I’m pretty happy with recippe – efficient and sensitive speakers ( not necessary synonims!) , good amp with power in regular FW bracket , few or none db of gain in box intended ffor selecting and adjusting signal source . However , during the years , playing with all sorts of signal attenuating devices ……resistive (P&G, Noble, TKD, ALPS,all sorts of stepped attenuators,blahblah) , LDR based Dropbox - PSM LS Cook Book.pdf inductive (Intact Audio , Sowter) , I came to conclusion that – besides principle of Signal Energy Preservation , impedances are also very critical , so buffer is conditio sine qua non ….. one step back , but that one step is what is necessary to achieve further two steps in front. It’s not easy to make both cheap and good soundiung buffer ; complementary Toshiba JFet buffer (see PSM LS CookBook) is becoming more and more PITA to make (money not being crucial , but hassle in obtaining them ) , while all other ones are either crude or bulky in comparison . To latest idea about no gain/small gain preamp I came by chance , already written here : What's wrong with the kiss,boy ? and Iron Pre | Zen Mod Blog , so I’m not going to repeat that.
