Amuzament Lenco 600 - 1972

Recommended Posts

Din plictiseal? am renovat ?i am pus ?n func?ie partea de amplificare de la un pick-up Lenco. ?n ciuda vechimii de 45 de ani se aude destul de bine. ?nlocuit cond cu Nichicon Gold ?i ceva Philips, reglat... mai trebuie s? me?teresc o carcas? ?i s?-i schimb trafo cu unul mai serios, ?sta are vreo 20VA s?racul. Schema amplifului e de tipul cu ie?ire prin cond, alimentare simpl? +32V, 2x6W, etajele finale tip Sziklai, bootstrap. Interesant e c? are ?i un mut comandat de comutatorul de re?ea, ce taie sunetul la deconectare cu doi trz. Zgomotul e mic, pu?ometrii nu fo?nesc, sunet tipic acelor ani cu boxele de atunci, azi ar fi cam exagerat la ton. Nu munceam la el dac? ar fi fost defect sau prea jegos.

Da, un exemplu ptr cine proiecteaz? azi cablaje, mai ales la traseele de mas? ?i alimentare. Un alt detaliu, intr?rile s?nt puse la mas? c?nd nu s?nt selectate, deci sursele trebuie s? fie protejate la ie?iri.

Domnule Zal, de unde va procurati aceste bijuterii?

Din t?rg de obicei, pick-up-ul ?sta m-a costat 30 lei. Cu partea mecanic? voi face altceva.

Ferice de cei care se pricep sa restaureze aparatrura electronica mai ales daca este de calitate caci unii  care n-au niciun fel de cunostinte in domeniu  o vand la preturi de nimic sau o arunca in caz ca este defecta.

Din pacate pentru mine, prin "tirgul Focsani" nu prea gasesti mare lucru.
