    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...

    Thanks in advance for your help. It's great to be part of a community of like-minded individuals. I've recently recapped an old Hafler DH-500. It's a bit unusual in that it has the pc10a version of the boards which don't quite match the manual available online. Anyhow, I've recapped it and...

    Need help replacing KR-5600 bridge rectifier M4B-3

    Need help replacing KR-5600 bridge rectifier S5VB20. I used dlucy's suggestion of a 400v/35a bridge on a previous KA-3500 restore, but I found it larger than the original. Space is tighter in the 5600. Could I use something like a KBPC804PBF? It's 400v/8a (Vishay). I plan to use 10,000uf...
