Hi,
blew a fuse in one of my MKIII's tonight. Noticed a while back that there was a bit of a buzz coming from the speaker hooked to it but didn't think much of it. The buzz did not get louder with increased volume from the preamp. The other amp is dead quiet.
Been using these since I assembled them about 18 months ago. Checked bias every couple of weeks. Have been trouble free since initial power up. Have about 1500 hours on them.
Using the original GZ34s rectifiers as supplied in the kit. I did a search here for blown fuses and found the usual comments, "reflow solder joints, ect". I'll be doing that tomorrow.
Nothing unusual noticed as the fuse blew. No bright tube displays. Just the amp going dark. Pulled the bottom off and the fuse was smoked but no evidence of other issues.
Anything else I should check out?
I'm going to check the GZ34s with my tester but it is an emissions tester so it may not be helpful.
Thanks for any suggestions!
Bob.
