Sziasztok!
Szeretnék építeni egy ilyen kis számítógépet. HifiBerry 2 RCA kimennetű DAC-al. Épített már ilyet valaki közületek? Fém házba szeretném a PI 4 táppal, elég ez így ha ráteszme a DAC-ot. Kell hozzá venti vagy elég neki ha tud szellőzni? Ill. ha ráteszem a DAC-ot akkor mennyi hely marad a házban a venti számára?
Üdv.. Ízirájder

Szevasztok.
Javitottam egy SU-V60 Technics erősitőt, ami végfokhibás volt.Jobb hiján az eredeti SVI 4004 helyett egy SVI 4003 sikerült szerezni
amivel tökéletesen működik. Kérdésem az lenne felétek hogy az eredeti SVI 4004 + - 59 V-os tápját birja e a 4003 hosszabb távon.
Sajnos erre vonatkozó adatot nem találok.
Megköszönném segitségeteket.
Üdv.
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!
Adott a fent nevezett rádió, ( SONY XR-5W497RB) ami bekapcsolás után nem ad tápot a beépített antennaerősítőnek, majd néhány nap múlva meggondolja magát és kiadja a tápot. Eltelik megint néhány nap és ismét nincs táp. Amikor nincs táp a VAG-COM diagnosztika szerint "Antenna short to ground". Megmértem a koax meleg ere és az árnyékolás közötti ellenállást, Mohm nagyságrendű. Az antennaerősítőnek külső tápot adva kb. 30mA az áramfelvétele,semmilyen rövidzár nem tapasztalható.
Találkozott már valaki hasonló problémával?
Segítségeteket előre is köszönöm:
Csaba
