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!

Sziasztok!
Magnó rész szól, de a rádiókból semmi, UKW-n a sztereó LED se világít ki, ki se tudom szedni a NYÁK-ot, szervízesek anno ezt hogy javították? Előlapot leszedtem, de a hátulját nem bírom leszedni mert a végerősítő/táp hosszú panelja keresztbe van az alján..
Valmi tápfeszültséghiányra gondolok..
