Sida loo sameeyo amps tube gacmahoodii

In article waxaad ku baran doontaa sida loo sameeyo amps tube gacmahooda ka mid ah qalabka duugoobay. Waa wax qarsoodi ah codka tuubada - ugu quruxda badan, taageerayaashiisa waxaa jiri doona wakhti kastaba, inkastoo xaqiiqda ah in suuqa waxaa ka buuxa tiro badan oo ah qalab yar oo cabbirkooda bixisaa transistors iyo chips. Ka fikir in faahfaahin dheeraad ah waxa aad tixgeliyaan in soo saaridda ee amp tuubo.

Cuntada - dhib ugu weyn

Haa, waa ku shaqeeya oo keeni kara dhibaatooyin, sababtoo ah waxaad u baahan doontaa labo danab talantaalli: 6.3 V u yahay xoogga buuxieyey, iyo 150 V waayo dhuumaha anode. Waxa aad marka hore aad u baahan tahay si aad u ogaato naftaada - dhismeedka awoodda mustaqbalka. From transformer awood this for korontada ku xiran tahay. Ogsoonow in transformer waa in ay ahaataa saddex windings. Haddii aan sida xoogga ah ma la samayn karaa Sammeecado tube gacmahooda.

Ka sokow sare kor ku xusan waa in ay ahaadaan xitaa iyo network (hoose) ee. Waa inay ku jiraan markooda sida badan in transformer waxaa sida caadiga ah ka hawlgala. Xataa marka load muhiim ah (oo korodha ee shabakadda ilaa 250 V) fuuli jiray waa in aan kululaado. Dabcan, cabbir ee korontada ku noqon doonaa halkii weyn, sababtoo ah ee size badan oo transformer ah.

rectifier

Waxaad u baahan doontaa inaad rectifier ah in wax soo saarka si ay u helaan ugu yaraan 150 Volts DC. Si arrintan loo sameeyo, u isticmaal xiriir circuit buundada diode ah. design korontada ayaa isticmaali kartaa dioska- D226. Haddii aad rabto in aad isku halaynta sare, isticmaali D219 ah (waxay leeyihiin a hadda hawlgalka ugu badnaan 10 Amperes). Haddii aad amps tube gacmahooda, ka dibna dhawraan xeerarka ammaanka.

Waxaa si fiican u shaqeeya blocks Diode Arrays Power. Waxaa lagama maarmaan ah in la doorto oo kaliya kuwa ay awoodaan in ay shaqeeyaan at voltages ilaa 300 volts. Fiiro gaar ah u shaandhaynta ee danab ku soo saarka DC - dhigay 3-4 capacitors electrolytic ku xiran ee isku midka ah. Awoodda kasta waa inuu ugu yaraan 50 microfarads, danab sahayda aad iyo aad bay 300 V.

Scheme preamplifier on tuubooyinka

Sidaas, hadda u dhaw in ay circuit laftiisa. Haddii aad qaadashada kordhiyo tube gitaar la gacmahaaga, ama haddii kale u ciyaaro music, waxaad u baahan tahay in la fahmo in waxa ugu muhiimsan - waa ammaan ah oo lagu kalsoonaan karo. The circuit ugu badan ka kooban yahay hal ama laba stage pre-kordhiyo iyo hal terminal. Shuruudaha ku salaysan yihiin transistors. Tan iyo markii ay jiraan tuubooyinka radio taas oo ka mid ah saldhigba waa laba transistor ah, waxaad badbaadin kartaa intii wakhti yar ah loogu rakibo.

Haddaba, waxa xubno ka kooban a amps tube. gacmihiisa u leeyihiin in ay soo ururiyaan oo dhan gasho dhisme hal. Ilayska ee pre-kordhiyo waa fiican used 6N2P, 6N23P, 6N1P. Iyo, inkastoo xaqiiqda ah in laambadaheeda waa kuwan le'eg oo midba midka kale, 6N23P codadka badan gooyeen. Ilayska Tani waxaa laga heli karaa qaybta madan ah (channels TV biiray), jir telefishannada madow iyo caddaan ah sida "Record", "Spring-308", iyo wixii la mid ah. D.

Joojinta stage kordhiyo

Sida saarka ilayska waxaa caadi ahaan loo isticmaalaa 6P14P, 6P3S, T-807. Oo kii hore wuu noqon doonaa yar, laakiin laba size ee la soo dhaafay aad u cajiib ah. Iyo T-807 anode iyo dhamaan sare ee weelka. Ogsoonow in ay daruuri u baahan tahay in ay isticmaalaan transformer ah in ay ku xidhmaan ku hadla ee tuubada Ulf. Tan la'aanteed ma suurtowdo in la sameeyo kordhiyo tube transformer kusaabsan ah oo aad gacmihiinna.

shaqo aad u fiican sida gudbiyeyaasha saarka TCEs loo isticmaalo scan ku yiilleen. Its hoose loogu fuuli u xiran dhexeeya korontada lagu daray iyo waalka saarka anode ah. In isku midka ah, capacitor ku xiran windings ah. Oo waa mid aad u muhiim in la doorto mid sax ah! Marka hore, waa in ay noqon warqad (nooca MBM). Marka labaad, awoodda waa inuu ugu yaraan 3300 PF. Waxaad uma isticmaali karo electrolytic ama dhoobada.

Qabsiga iyo rikoodh

Samee rikoor u noqon doonaa mid aad u fudud. Waa ku filan si ay u sameeyaan laba Sammeecado isku mid. Waxaa laga heli karaa jir farsamo Soviet kordhiyo tube rikoor ah. Iyada oo gacmahooda, oo aad ku celin kartaa dhismaha. Laakiin waa in aynu tixgeliyaan qaar ka mid ah sifooyinka gaarka ah:

1. gacanta mugga si toos ah ugu xiran in ay aqbasho ee kordhiyo ah. resistor A variable, taas oo loo isticmaalayo, waayo, waa in la doortay sida in mid ka mid kiiska on dhidibka ayaa laba walxood. In si kale loo dhigo, marka qoqobada xamili in la beddelo iska caabin ah oo ka mid ah laba resistors mar.
2. shuruudaha la mid ah oo u dirato soo noqnoqoshada. Waxaa la wareegeen circuit anode of preamplifier ugu horeysay transistor ah.

Housing for kordhiyo

Haddii aad kordhiyo a tube gitaarka gacmahaaga, ka dibna u isticmaali jirka ka mid ah biraha sameeyey, waxa macno. Isagu ma aha baqay inuu noqon weerarada iyo naxdin leh u yar oo kale. Laakiin haddii aad u qabaneysid kordhiyo si loogu isticmaalo guriga, tusaale ahaan, in ay ku xidhmaan ciyaaryahanka, computer ah, waa macquul in la isticmaalo jirka ah ee geedka. Laakiin waa in aan ku haay maanka in transformer awood waa la jecel yahay in lagu lifaaqo jidhka taasi oo ka gaskets caag. Iyada oo ay gariirka caawimaad hoos u dhac.

Inta badan waxay ku xidhan tahay waxa ay noqon doontaa jirka ah ee amp tuubo. The gacmaha Macallimiin badan ka qolof sheet aluminium abuurtay. Haddii laambadda saamayn doono xitaa gariirka yar, ay bilowdo inay baayici Roobka. isbedbedelka waxaa loo maqalka doonaa, oo natiijada - tijaabadooda ku hadla. Waxaad sidoo kale u baahan tahay inaad bas caadi ah, oo waa inay qaataan meel u dhow oo dhan laambadood ka mid ah design ka. All silig ka dhigeen, oo waa signal a waa in loo gaashaan sida ugu badan ee suurtogalka ah - taasi aad uga takhalusi doonaa noocyo kala duwan ah faragelinta.

Qorsheyaasha la transistors

design kale oo xiiso leh - a Sammeecado tube-transistor. Gacmihiisu waxaa la samayn karaa oo keliya habeenkii ah. Laakiin halkan naqshado laambad waxaa sida caadiga ah lagu sameeyo taararka to-dhibic. Eebe waa kan ugu haboon oo fudud. Oo haddii transistors waxaa loo isticmaalaa, waxaa lagama maarmaan ah in aad dalbato taararka ku daabacan. Intaa waxaa dheer, baahida loo qabo in ay leeyihiin danab a 9 ama 12 volts u yahay xoogga marxaladaha transistor ah. War sidee transistors waxaa kaliya loo isticmaalo dhismaha stage pre-weyneeye. In si kale loo dhigo, waxaad yeelan doontaa oo keliya hal laambad - yada wax soo saarka (ama laba, haddii ay tahay version rikoodh a).
