    SX-727 blown fuse - please help identify parts

    Merry Christmas AK'ers! I could use a little help solving a blown fuse problem on a SX-727. This unit was my first recap project, done 4 years ago. Following AK threads I bravely dug into a SX-727 to recap it, but little did I know how hard/easy it was! I figured even if it blew up it could...

    Marantz 4230 blowing fuse

    I got this 4230 and I found out the bridge rectifier was shorted, therefore fuses would immediately blow. I replaced it with a compatible bridge and turned it on with a DBT. The 100W light dimmed but not as much as it does with other receivers such as the 2225 and 2230. The dial lights came on...

    Sansui QRX-5500 Died changing the lamps

    Good Evening AK'ers. So I did a rather stupid thing tonight. I had my 5500 apart on the bench for a cleaning and lamp replacement. I'm a novice at this so bear with me. I changed out the fuse lamps and those were all working great. I needed to replace one selector bulb and I forgot to turn off...

    Sansui G-2000 Keeps Blowing Fuses

    I have a Sansui G-2000 that I've owned for approximately three years, which I purchased from a buyer on eBay. The problem I'm having is that one of the fuses keeps blowing now. It is a 4A 12.5 volt fuse located in a bank of three fuses, to the side of the power transformer. It is the right most...
