2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Nov yog qhov phiaj xwm me me rau cov guitarists. Nws xim lub suab nrog qee lub raj tsis sib xws (txawm hais tias nws muaj ntau dua li kev tsav tsheb tsis zoo), kev sib zog me ntsis, thiab nws txhawb lub teeb liab, ib yam nkaus. Nws yog "kev txhawb nqa qias neeg," nrog qhov tsw ntawm cov raj, thiab tuaj yeem muaj txuj lom tiag tiag li amp (thiab nws ntxiv punch.) Tam sim no Nrog Ntau Ntxiv! Hloov kho cov phiaj xwm tshiab ntxiv, saib nplooj ntawv kawg… Ntxiv rau, nws muaj qhov hluav taws xob qis-tsis ntau dua 13V, yog li nws muaj kev nyab xeeb zoo rau “raj neophytes” los tsim. Tsis muaj kev phom sij txaus ntshai nrog qhov no. Nws tuaj yeem siv tau nrog lub roj teeb 9V (tab sis nyeem cov kauj ruam ntawm "Powering Options.") Nrog tsuas yog qee qhov pheej yig thiab qhov yooj yim Circuit Court, qhov no yuav tsum yog qhov yooj yim thawj lub raj raj project! Kuv tsis tau siv lub vis dis aus cam, yog li "youtube" suab yog ib nrab-qhov tsim nyog zoo. Tab sis cov ntawv mp3 (saib hauv qab, hauv qab cov duab) zoo dua … nws yog tib lub suab..

Kauj ruam 1: Tom qab

Lub tshuab nqus tsev muaj cov yam ntxwv ntxim nyiam hu ua "starved cathode" kev ua haujlwm, uas ua rau muaj qhov cuam tshuam zoo thaum lub raj ua haujlwm ntawm qhov hluav taws xob qis heev. Matsumin's Valve Caster tube booster yog kuv qhov kev qhia rau cov raj hluav taws xob qis. Cov nqi hluav taws xob no, qhov tseeb, yog qhov tsawg heev uas ntau lub tshuab hluav taws xob qub qub yuav qhia rau koj tias cov raj yuav tsum tsis ua haujlwm txawm li cas los xij … Cov hluav taws xob qis heev uas cov rhaub dej kub yuav tsum tsis txhob ua haujlwm (tab sis lawv ua.) Matsumin txoj haujlwm siv 12AU7 raj, thiab yog qhov tsim nyog tsim nyog. Qhov kev tsim no, ValveLiTzer, siv lub raj me me coj txawv txawv: 12FQ8. Vim li cas siv lub raj coj txawv txawv? Vim tias kuv muaj txog 25 ntawm lawv, thiab tsis muaj guitar amps lossis stompboxes siv lawv. Yog li vim li cas ho tsis tsim qee yam? Tab sis 12FQ8 tsis yog lub raj suab zoo. Nws yog ntxaib-triode, tab sis nrog 4 daim hlau, thiab ib qho sib koom cathode. Nws puas yuav ua haujlwm zoo li lub suab nrov? Tsuas yog ib txoj hauv kev kom paub…

Vim li cas lub npe ValveLiTzer? Cov raj no tau los ntawm lub tshuab hluav taws xob suab nrov hauv lub cev WurliTzer tsis muaj dab tsi. Muaj ob peb lub vev xaib cov lus pom (rov: yog 12FQ8 qhov tsim nyog rau kev siv guitar amp?) Muaj peev xwm siv ntau txoj hauv kev yooj yim dua. Saib lawv nplooj ntawv tom ntej rau cov ntaub ntawv ntawm kev yuav lub raj (tshwj tsis yog tias koj pom WurliTzer qub …)

Kauj Ruam 2: Qhov Chaw

Saib cov kauj ruam #4, Kev Tsim, rau cov npe teev tseg, tab sis ntawm no yog qhov nrawm nrawm ntawm ntu:-cov ntaub ntawv hlau-ib qho 9-tus pin me me raj ntsawb (qhov loj me rau preamp raj zoo li 12AX7, thiab lwm yam.)- -ib lub 12FQ8 tube-- (2) 1/4 in. mono phono jacks-(1) Audio-taper POT (500K)-(1) Linear-taper POT (50K)-ob peb mylar capacitors (mylar rau teeb liab, tej hub lossis lwm yam rau kev hla dhau.) Los yog polypro, polyester, thiab lwm yam, rau lub teeb liab zoo, ib yam nkaus.- ob peb 1/4 watt resistors- ib qho footswitch, ON/ON ntau yam- ib lub hwj chim (roj teeb lossis 9V-13V mov)-lub jack rau lub hwj chim nkag, lossis lub roj teeb

Tau Txais 12FQ8 Tubes Muaj qee qhov tsis zoo txog kev siv lub raj no. Txawm hais tias cov no tsis yog ib txwm muaj, lawv tsis nyuaj rau pom lossis kim heev.https://tubesandmore.com muaj lawv tam sim no rau $ 5.50 ib lub raj. Feem ntau lawv yooj yim mus nrhiav hauv Ebay, ib yam.

Kauj Ruam 3: Tsim

Tsis muaj dab tsi txaus ntshai tshwj xeeb txog tus tsim. Nws yog tus txheej txheem ncaj ncees preamp hom ntawm Circuit, tab sis siv lub raj khib nyiab ntawm qhov hluav taws xob qis heev. Ua rau qhov qis hluav taws xob, cov phaj resistors tau siab heev piv rau qhov qub. Lub lauj kaub suab-taper yog qhov zoo tshaj plaws rau ntim. Pot #2 (P2) teeb tsa qhov tsis ncaj ncees, thiab cuam tshuam tag nrho cov yam ntxwv ntawm cov zis. Ua si nrog nws hloov qhov nce, thiab qib kev sib zog, ib yam. Lub lauj kaub tawm-taper ua haujlwm zoo rau qhov tsis ncaj ncees. 0.1uF bypass cap (C3) yog qhov me me, muaj txiaj ntsig zoo. Txhua yam los ntawm 0.1uF txog 10uF tej zaum yuav raug hloov pauv-qhov txiaj ntsig loj dua yuav txhawb nqa cov ntses bass thaj tsam, thiab qhov ntim ntawm cov nyhuv … Kuv tau siv lub hau me me (tantalum?:-P) ntawm no txij li tus nqi me me, tab sis cov hluav taws xob tuaj yeem hloov tau yog xav tau qhov loj dua. Ib 10uF tau sim ua ntej, tab sis yog farty / bassy heev. 1uF tej zaum yuav yog qhov kev xaiv zoo, thiab hauv txoj kev xav, 12FQ8 tej zaum yuav muaj peev xwm ntawm qee qhov kev lom zem heev. Txawm li cas los xij, kuv tsis ntseeg cov no tuaj yeem ua tiav tau yooj yim ntawm cov hluav taws xob qis.

Kauj ruam 4: Tsim

Nov yog cov lus qhia teeb tsa / thaiv daim duab.

Feem ntau ntawm cov khoom siv tuaj yeem muab ncaj qha txuas rau lub qhov (9-pin tube socket). Nws yooj yim heev yam. Nws tseem compact heev, yog tias qhov teeb meem. Kuv ua ke 3.5mm lub mloog pob ntseg rau lub zog, raws li kev xa khoom sab nraud ua haujlwm zoo tshaj plaws rau kuv. Tsis muaj qhov hloov/hloov pauv, tab sis ua/tawg hom ntawm phono jack ib txwm tuaj yeem hloov pauv thiab siv ua qhov hloov pauv (ntawm thaum ntsaws ntsaws, tawm thaum tshem tawm.) Txoj kev hla hla tsuas yog qhia lub teeb liab ib puag ncig. Lub raj txuas txuas ntxiv tam sim no txawm tias hloov tawm. Qhov tsis zoo rau roj teeb, tab sis lub raj xav tau 8-10 vib nas this kom sov, yog li nws tsuas yog qhov kev xaiv ua tau zoo (thiab ib txwm muaj feem ntau ntawm lub qhov ncauj.) Nws nyuaj me ntsis los nrhiav hom footswitch no. Nws yog ON/ON SPST hloov. Txhua qhov hloov pauv tshwj xeeb rau guitar FX lub thawv yuav ua. Nws tsis yog qhov "hla dhau qhov tseeb," vim nws tsis hloov pauv cov ntaub ntawv tawm tsam …

Kauj Ruam 5: Hloov Kho Daim Duab Daim Duab (V0.4)

Nov yog qhov hloov kho tshiab ntawm ValveliZter nrog "nce" POT, thiab qhov tseeb hloov pauv.

Muaj PDF suav nrog, zoo li ua ntej. Yog tias koj pom teeb meem, qhia rau kuv paub …;-)

Kauj Ruam 6: Ntxiv Stompbox Case…

Kuv muaj ib lub thawv ntawm cov thawv ntim zaj duab xis qub, thiab txoj haujlwm no me me txaus kom haum tau yooj yim. Zoo li ib qho "stompbox," qhov no yuav tsum tau ua hauv lub thawv hlau thaiv.

Cov qhov tsav tau raug laum thiab tom qab ntawd nthuav dav nrog qhov yooj yim "kauj ruam" laum ntsis. Ib qho lus qhia: txhawm rau sib sau ua ke tau yooj yim nrog lwm lub thawv ntim khoom, cov tswv yim yuav tsum nyob ntawm sab xis, tso tawm ntawm sab laug (kuv yog qhov tsis sib xws, oops.) Yog tias cov roj teeb yog qhov siv hluav taws xob zoo dua, tom qab ntawd lub thawv loj dua yuav zoo dua. Muaj ntau txoj hauv kev los tiv thaiv lub raj los ntawm kev puas tsuaj. Ib txoj hauv kev zoo yog txhawm rau rub rub lossis tuav ntawm txhua sab. Kuv tsis tau koom nrog qhov tsim. Lub peev xwm me me rau cov leeg. Tab sis yog tias koj tab tom gigging nrog F/X no, lub raj liab qab yog lub tswv yim tsis zoo.

Kauj Ruam 7: Kev Xaiv Ua Haujlwm

Chav tsev no yuav ua haujlwm nrog DC voltage ntawm 9 - 13V. Ib qho hluav taws xob ntau dua yuav FRY lub raj xa hluav taws xob (qhov no yog tus qauv 12.6V cov raj xa hluav taws xob.) Qhov siab tshaj plaws rau cov raj xa hluav taws xob yog qhov ntsuas hluav taws xob, +-10%. Yog li 13.86V yog qhov siab tshaj plaws qhov hluav taws xob ua ntej cov ntsiab lus kub hnyiab tawm (thiab kuv yuav tsis khiav ib lub raj filament uas siab, tsis hais txog qhov tshwj xeeb.)_{Cov tub rog tub rog yuav nkag siab tias qhov hluav taws xob siab dua tuaj yeem siv rau cov raj yog tias cov kab hluav taws xob thiab phaj hluav taws xob sib cais. Yog tias yog, qhov ntsuas qhov ntsuas hluav taws xob yuav tsum tau hloov kho kom tswj tau qhov hluav taws xob siab dua, ib yam.}Kuv tau siv txoj cai tswj hwm 13V, thiab chav nyob ntsiag to heev. Yog hais tias siv lub wallwart tsis raug cai, cia siab tias yuav muaj suab nrov ntau … Cov khoom siv sib txawv uas tswj tau yuav tsuas yog ib qho xwb. Yuav kom ncaj ncees, cov nyhuv yog me ntsis ntxiv tubey @ 9V, txawm hais tias qhov ua kom muaj zog tsawg dua. 9V roj teeb tsis tas ntev, li cas los xij. Chav tsev kos txog 135mA @ 9V. Kuv yuav tsis cia siab tias lub roj teeb 9V yuav nyob ntev ntau tshaj li ib teev nrog qhov kev kos tam sim no. NiMH AA rechargables yuav ua haujlwm zoo. 7 lossis 8 NiMH hlwb yuav tsum ua kom zoo.

Yog tias kev tswj hwm 9V txog 13V tsis muaj, nws tuaj yeem tsim tau yooj yim. Tus tswj hwm LM317 zoo tshaj rau txoj haujlwm no. Txij li nws qhov hluav taws xob tso tawm tau kho tau, nws zoo dua li tus tswj hwm ruaj khov-raws li tau sau tseg saum toj no, qhov hluav taws xob qhov hloov pauv qhov cuam tshuam me ntsis …

Kauj Ruam 8: Ua Tau Mods

Qhov Circuit Court no yog thawj kauj ruam tiag tiag. Kuv xav ua raws qhov kev xav ntawm lub raj bluesy amp, tsis ua "fuzz," ib qho hais. Muaj qhov pom tau zoo heev hauv qhov nce, thiab zoo nkauj 70's lub suab pob zeb, zoo li yog, tab sis koj yuav xav tau lwm yam… ntau tshaj qhov punch thiab qhov txawv:- Ua kom R4, thiab R3 ntxiv.- Muaj peev xwm ntau dua ntawm kev sib txuas resistor C1 thiab C2. Kuv xub muaj C2 @ 0.068uF, tab sis muaj qhov ploj ntawm qhov tsis meej (tsis muaj teeb meem loj yog qhov kev cuam tshuam loj tshaj yog lub hom phiaj.) Tsuas yog nce txhua rau 0.02 yuav muaj qhov tshwm sim pom tau..-- Loj cathode-bypass capacitor (C3). NCO TSEG: qhov no tau lees paub-saib cov nplooj ntawv kawg rau kev hloov tshiab, suav nrog qhov nce qib nce nrog qhov hla hla loj dua … Tsawg qhov nce thiab cuam tshuam, ntau lub raj ntshiab:-Tso R3 txog 220K Ntxiv Kev Hloov Kho:-R4 tuaj yeem yog hloov nrog 2M POT.-- Los yog, hloov ob qho R4 thiab R3 nrog ib leeg 2M lossis 3M POT.-- Ib lub suab tswj lossis ob qhov tuaj yeem ntxiv. Lwm cov tswv yim … Qhov no yuav ua rau pem hauv ntej zoo rau LM386 miniamp, ib yam …

Kauj Ruam 9: Dab Tsi Ntxiv?

Raws li kuv muaj ntau dua 25 ntawm cov hlab no, cov kauj ruam tom ntej yog dab tsi? Pom tseeb, tsis yog? Lub ValveLiTzer II! Yog, ob lub raj, plaub theem ntawm raj preamp zoo …

Kauj Ruam 10: Tau Txais Kev Tswj Tshiab, Version 0.4

Nov yog qhov hloov tshiab rau txoj haujlwm, uas ntxiv me ntsis ntawm kev tswj tau nce. Cov ntawv dhau los tau tua ntawm lub raj "ntshiab" lub suab, tab sis kuv tau thov kom muaj hwj chim ntau dua! Ua kom hla hla hla ib leeg (C3) tiag tiag ntxiv qhov nce. Kuv tau teev nws li 100uF, tab sis ib qho txiaj ntsig los ntawm 22uF nce mus ntxiv yuav nce ntxiv. Ib POT (P3) tau ntxiv los kho qhov nce ntxiv. C3 tuaj yeem ua tau yam tsis tau ntxiv POT, tau kawg. Qhov qub "Bias" POT tseem nyob hauv qhov chaw. Ob qho ua ke tuaj yeem hloov kho kom haum … Qhov:

C3 100uF, polarized electrolytic, (16V yam tsawg kawg nkaus)

P3 50K suab taper potentiometer
