Sziasztok!
Azt szeretném kérdezni, hogy a fenti fejegység bekapcsol-e asztalon, kijelző nélkül. Nem kapcsol be hibával hozták, de nem találok benne semmi rendellenességet. Áramfelvétele 0,4A, de semmit nem csinál. Lehet, hogy a kijelzőre vár?
Üdv.
Üdvözlet mindenkinek!
Adott a címben említett rádiós erősítő,amikor hozzám került semmilyen hangot ne adott ki,a táp egyik ágában a biztosíték ment ki csere után már szól is,de FM sávban hangolva csak folyamatos sistergés hallható semmi változás nem érzékelhető.Mi lehet a probléma,találkozott már valaki ilyen hibával?Rajzot sem találtam hozzá,esetleg tud valaki?
Előre is köszönöm
Üdv:Mitu
Sziasztok!
Van nálam egy Ecler PAM 600 régi szériás gép. Az egyik oldali relének megszakadt a tekercse, nem találok sehol a neten sem hasonlót!
48V 20A Eredetileg morse érintkezős volt de beültetéshez a két felesleges lábat kivágták. Még gyári volt a relé nem úgy barkácsolták bele.
A készülékben minden feszültség rendben lévőnek tűnik, de a reléken mindkét oldalon 63-64 volt van. Talán ezért halhatott meg vagy csak egyszerűen elfáradt... nem tudom...

Hi All,
Does anyone have any experience of working on this radio, its the small Grundig with a leather case designed by F.A. Porsche.
I have recently repaired one with corroded battery contacts which had obviously not worked for many years.
Its now working perfectly on FM, but MW and SW1 and SW2 have no reception, just noise.
If I leave the radio connected to a 5v power supply for many hours it does actually get some reception on AM, but its not consistent. I'm thinking the fault is somewhere in the 'front end', oscillator stage perhaps.
I have checked the AM coils and wave selector switch are OK and everything is visually in excellent condition.
Reading various reviews on this radio confirms they were sold very cheaply in the USA and many customers have complained there is little or no sensitivity on AM, whilst others say it works perfectly. This makes me wonder if there is a common fault on these which someone may know, before I start with my test equipment to try to find the problem...
Any advice would be much appreciated!
