Üdv Sziasztok
Ha felismerné valaki melyik lemezjátszóban lakozna ez az erősítő.
UL1401-el épített unitra vagy telefunken erősítő.
Elvileg Mister Hit 71-ben lenne építve UL1403-al
Kellene egy pár kondenzátorról infó kb. mekkora értékűek lehetnek
c102, c113,c108,c109

Hi
I'm looking for a schematic diagram for this equipment:
Professional Power Amplifier XA-1000
The main fuse was blown and according the owner it blowns again after replacement.
He used a 40 amp fuse. The original fuse is not around anymore and there is nothing written outside on the label. So it's somewhat a lottery about the correct fuse rating.
Anyway, I would like to repair this equipment but without a diagram it would be a pain and nearly impossible.
Tryed to find a diagramwith Google search - negative. Also the manufacurer ist unknown this days.
Maybe a reader has more information aboutb this.
Thanks a lot

Dear Friends,
I am having a problem with the above mentioned amp. When I increase the volume from 0 to a quarter level the sound is OK. If I increase the level above quarter onwards , the sound becomes fuzzy and distorted. I have tried replacing the 2 filter capacitors(8200uf 50v) with 2 (15000uf 50v) caps but it is the same. Can someone give me a clue what can be causing this problem.
Thanks

A címben szereplő CD lejátszó javításában szeretnék segítséget kérni. A történet a következő, kaptam ezt a 4-részből álló hifit. Az összekötő szalag kábelei elkallódtak ezért megpróbáltam kivezetékezni. Minden rendben ment amíg a cd-t és a magnót összekötve rá nem kötöttem, azóta a cd csak éppen halható teljes hangerőn, a lemezt 3mp alatt megtalálja lejátsza, léptet, pörget, stb. csak halk. Az erősítő, rádió, magnó rendben van. Most jut eszembe a CD kiír egy U-70 hibakódot de lemez behelyezés után eltűnt s lejátszotta a lemezt. Érdemes vele bibelödni.?? Előre is köszönöm.
