M51533L sztereó dekóder - MEGOLDVA
Sziasztok! PIONEER SX-202 RECEIVER-t vettem nemrég hibásan. URH-n nem szólt, mert át volt alakítva OIRT URH-ra. Ezt rendbe tettem. Elég profi KF. jele van az M51533L IC-ig. A hangolásjelzés (LED) és a muting rendesen üzemel. Viszont az IC kimenetein azonosan kicsi a demodulált jel mindkét csatornában. Maximálisra állított hangerőnél van normál szobai hangszínt. A sztereó vétel nem üzemel. Az M51533L IC-nél mért DC munkapontoknál két lábon (5. és 14.) van eltérés. Ezek mért értékeit pirossal beleírtam a mellékelt kapcsolási rajzba. Az IC sajnos kifutott típus a HQ Elektronikánál, nem rendelhető. Lehet esetleg más hiba is, mint IC hiba? Mi a véleményetek? Üdv.: Kumi
Grundig YB-P 2000 not working on AM bands
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!

Videoton RA 3101 rádió restaurálás
A legutolsó Videoton csöves rádiót az RA 3101-et elkezdtem feléleszteni. A törékeny műanyagalkatrészeket kicseréltem a hullámváltóban de félő hogy csuszkák nem ugyanúgy kerültek vissza. Keresek kapcsolási rajzot. BUÉK!
