Blown fuse [Resolved]

[tubenoob]

That is the lead from the UF4007 installed between 18L and 20L in the last step on page 38 of the manual.  While it's a bit long, it isn't touching anything else.  I will certainly trim it up a bit to be sure though.  At this point, should I just consider reflowing everything attached to that particular 6 lug terminal? Or both? Thanks again for the help.

You could remove the 270 ohm resistor that crosses over the power transformer, then try firing up the amp again.  If the fuse does hold, you will need to leave your meter leads on the 220uF cap on the terminal strip with the UF4007 diodes to discharge it, otherwise it will hold its charge and give you a tingle when you go to continue working on the circuit.

Thanks for the guidance, Paul. I will do so and then reflow.  Fingers crossed.

After discharging the capacitor and reflowing the 6 lug terminal (17-22), it WORKS!! Sounds great right away.  Can't wait for it to burn in.  Many many thanks Paul.  The help was very much appreciated!!

That's odd, I don't think I've ever had lack of soldering cause a blown fuse, but I'm glad you got it sorted!
