MV-100watt blowing fuse-Solved
Posted: Wed Feb 02, 2011 7:03 pm
Hi
I just rewire my Metro 100watt LarMar MV mod to this link http://home.comcast.net/%7Ejbjdav26/195 ... l%20B+.JPG" onclick="window.open(this.href);return false;
I then played it last night and it worked fine, so i put in its case. I then tried to play it today and it keeps blowing the Mains 4amp fuse. Why would this be? I didnt unbolt anything, and the fuse also blew when the preamp and power tubes were pulled out. So I checked all of the resistors and they are good. I am going to check the resistance on the filter caps to see if one went bad or not. If not though what would cause this? It was working flawlessly before I put it back together. I also noticed that in the link above the Pl caps are .22uf which mine are, and in the wiki page for Lar/Mar it shows .1uf Pl caps, does it make a difference which wiring layout I use (wiki vs. SDM)?
Thanks
Tyler
