Üdvözlet Mindenkinek!
BRG M8 szalagos magnóhoz keresek hajtószíjakat.Aki tud beszerzési forrást, kérem, jelezze.

Üdvözletem Tisztelt Mesterek!
Tanácsot , segítséget kérnék.
Az említett Thomson DPL-580HT géppel bajlódok.
Hálózatra csatlakoztatva a készenléti led világít, kapcsolót nyomva indul, feszültségek megközelítőleg jók.
Kikapcsolni nem lehet , csak kihúzni , de ismét indul.
Kijelző egység tápja , feszültségei magasak.
Pl:IC-103 stab. be és kimenetén azonos feszültség (5V) mérhető,a kisütő ellenállás miatt , tehát az IC-101 Microcontroller (HT48R05A-1) nem megy.
A meghajtón Q102 (PT6315)-n is magasabb feszültség mérhető, 24V helyett,31V.
Kérnék segítséget a tovább lépéshez.
Valakinek van bontott gépe?
Érdemes tovább bajlódni vele?
Rajz a Tanyán van, kijelző részt nem tudtam úgy kicsinyíteni hogy a topikba mellékeljem.
Előre köszönve a segítséget: Öreg Tom
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!

üdv:
Sony DTC 790 DAT magnó befűz, de nem indul a lejátszás.
Befűzéskor felpörög a fej, azután leáll, CAUTION hibajelzéssel.
A kazettát is csak úgy lehet kivenni, ha ki és bekapcsolom.
A kazettaérzékelő kapcsoló, a két motor, elektromágnesek, tápok ellenőrizve.
Rajzot a Tanyáról letöltöttem.
Valaki ismeri, vagy javított ilyet?
Bálint
