Sziasztok! Végigolvastam az oldalon a HS 280 hangváltó bekötés problémát,ugyanebben a cipőben járok én is.Kaptam egy HS200-as 4 Ohm/25W orion hangfalat,gondoltam jó lessz centersugárzónak.A hangszórók kifogástalan állapotban vannak.A gondom az amit olvastam a fent emlitett topikban is.Miért van forditva bekötve a magassugárzó kondija(a pozitiv sarka megy a dómsugárzóra).És nem nagyon értem,hogy miért 10Mf,szerintem 4.7Mf kéne lennie.A középsugárzónál is 10Mf van ezt még értem.A mélynyomón 47Mf van paralel.Én kicserélném mind a hármat bipolárisra.És természetesen átkábelezem elfogadható kereszmetszetü vezetékkel.(ami benne van na az öv alatti)Azt kérdezném Tőletek hogy a magasra jó ha 4.7Mf kondit teszek? Szeretném ezt a hangfalat rendbe hozni. Üdv Mindenkinek! György

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!
