Group-buy Amplificator SARA

[Vizitator]

Nu stiu de ce, dar DHL este evitat in zona mea, pentru comenzi casnice. Bun, 11 kile pare mult, sau putin, cand am comandat o imprimanta 3d, ieftina de la creality, a venit foarte repede si fara nici o problema si nu era usoara. Cu DHL am comandat o singura data din sua, s-a invartit de vreo 3 ori, pana la urma a trebuit sa platesc nu stiu ce taxa de brokeraj vamal, la telefon, nu la livrare, de atunci ii evit. Astia au livrat in cutia postala, nu cred ca era dhl.

 

Oricum pana la urma or sa vina si va fi necesar un topic de sfaturi punctuale, ca la 175 ar trebui sa fie vreo 40 de musterii din care vreo 2-3 mai incepatori, ca mine.

Dupa ce apar cablajele, cu siguranta va trebui sa apara un topic in care sa fie explicata punerea in functiune. In principiu, Raimond ar trebui sa dea detaliile de finete. Eu voi incerca, pana atunci, sa sistematiz cat mai bine detaliile legate de plantarea acestora si o fixare mecanica cat mai facila pe cablaj.

In principiu, dupa cum am spus, daca este montat corect, fara greseli, trebuie sa porneasca din prima, fara probleme. Trebuie doar foarte mare atentie la lipirea componentelor.

Acum 1 oră, Dan85 a spus:

Nu-i prima data, stiu cu cine am de a face... Taxa aia nu vreau s-o platesc si o consider un abuz, o smecherie legislativa cu dedicatie !

Procedurile cad in sarcina lor si le-am platit deja serviciul.

 

 

Nici eu nu le-am dat 5 lei in plus fata de ce am platit chinezului cand am luat comanda, ca nu mi s-a parut corect. 

Ma enerveaza asteptatul ala mult. De cate ori ii sunam, ma omorau ca nu le dadea drumu vama si sa mai astept. O data am stat o luna dupa un rahat de colet 

[franzm]

Dar cât a cerut chinezul pe transport? De multe ori costurile transportului sunt incluse în pretul marfurilor si nu sunt vizibile explicit. Si nici amploarea serviciilor comandate de la transportator nu este cunoscut cumparatorilor.

Ar trebui să se înființeze un Fanclub SARA, daca tinem seama ca numai aici s-au comandat placi pentru câteva zeci de amplificatoare.

Mai fain o sa fie cind vor fi majoritatea finalizate și vom putea avea un topic numai cu amplificatoarele Sara...... 

Din păcate le vom asculta doar.... pe YouTube......

Eu am returnat mufele cumparate pentru ca mi-au fost livrate cu DHL. Ce naiba, am dat 13$ pe ele cu transportul inclus si DHL-ul vrea sa-i dau 100 de lei pentru comisionariatul vamal. Cativa ani de zile mi le trimiteau cu posta si nu plateam nimic iar acum ii gasira pe astia de la Gestapo. Le-am zis chinezilor sa trimita clasic cu posta si alta data sa intrebe cu cine vreau transportul chiar daca e gratis, mai ales ca au 4...5 variante.

[sk24bpo]

Nu va faceti griji. Amplificatorul porneste din prima fara fitze. Daca vor fi neclaritati le vom rezolva impreuna. Intre timp puteti sa va ganditi si la circuitele auxiliare de genul soft-start, speakers-delay, protectii la DC, dc-trap, etc... puse toate pe o placa. De asemenea poate va exista un group-buy si pentru transformator sau smps. In fine, nu e graba.

[CristiZ]

Sunt doua firme in Iasi care fac trafuri, Petra si Necom. Daca vreti, pot ajuta

[daniels]

Domnul Cristi am primit azi radiatoarele. Au calatorit foarte bine. 

Daca ne vom intalni vreodata dau o bere. Multumesc!

[maxente]

Multam frumos si din partea mea. Am luat acum coletul de la posta si e ambalat perfect.

Din pacate eu nu stiu cand voi finaliza amplificatorul asta. Initial radiatoarele le luasem pentru inca un amplificator hexfet cfamp. dicutat in alt sibiect. O sa vad pe parcurs pe care il fac.

 

[djlove]

Am primit si eu coletul cu radiatoarele, totul este in regula, multumesc frumos

M-am uitat un pic pe cablaj (adica la un colt)  si vad ca e o diferenta fata de schema publicata. Diodele Zenner de 6V2 au punct cu condensatoarele? Pe schema nu au.

Valorile sunt 6.2, ca am vazut pe schema lui raimond diode 1N5225B si 1N5231B care sunt de 3V respective 5V ?

[vlad228]

Da, diodele fac punct comun cu acei condensatori de 1uF, iar diodele zenner sunt de 6.2v.
