REPARATION

Présentation:
Causes et état des pannes: le viellissement est la principale source de pannes rencontrées sur les Emetteurs
Celui-ci affecte les composants mécaniques et électroniques
Composants mécaniques (ou assimilés):
- Fils argentés qui s'oxydent d'où un changement dans la transmission et l'impédance; ce qui s'ensuit est une désadaptation des circuits d'accord d'origine des transitors HF, lesquels claques car ne travaillant plus dans la bande de féquences autorisées
- Graisse de conduction thermique des transistors de puissance "séchée" et ne conduisant plus, les transistors s'emballent thermiquement et claquent!
- Condensateurs "Disques" (ou assimilés) HS; placés en découplage il ne font plus office, les accrochages font leur apparition, perturbent
