Hali mindenki.
Adva a fenti fetes, békebeli erösitő.
bizonytalan működés jellemzi..mérés, kontakthibák, kondizás, poticsere után már csak az előfokban lévő (processornak mondott") fekete, beöntött 32 lábú modullal van a gond...
Az egyik oldali nem.mindig ad ki jelet..
a másik oldali pedig torzitott jelet ad ki.
ha kiveszem ezt a modult és a be-kimenetet átkötöm akkor működik rendesen...a rajza alapján ez a modul szabályozná vissza a végfokot túlvezérlés esetén is ..
Ismeri valaki ezt a modult? Gondolom a beszerzése már reménytelen..esetleg bontásból..
Csatolok néhány rajzrészletet erről a modulról..
Üdv.LF

Hello, I'm looking for the service manual for Brüel & Kjær 5935.
Given:
Victor TT-71, neon lamp does not light, speed is lower than normal. This is subsequent some short circuit the owner does inside the device. No further details.
I found out the VICTOR QL7 have the same motor driver amd I downloaded the service manual that I attached here in case this manual is not already uploaded.
Looking at the diagrams I found out that at TP3 (same with pin5 of IC803) instead if that rectangular signal, I have nothing but 5VDC and a negative or positive short spike whenever I'm starting or stopping the motor and
Under the circumstances I suspect IC803 is defective. The bad thing, IC803 is NPC SC8043. Also I wonder if the crystal is fine (except that I wonder what can be wrong with a crystal after some short circuit).
Does anybody have any more suggestion?
Also, where can NPC SC4043 be sourced? Also, a crystal 9.054MHz?
Thanks in advance,
Corneliu
