Carl Z	Re: 5E3 Filament circuit Mike; I hope you realize this is probably more addictive than crack. Anyway, you picked a good amp for a first project. The heater circuit is probably the hardest part of the amp to wire up...physically. You'll probably end up take a few passes at getting it clean and tight. First off use 18 gauge wire. You can use a thinner gauge but you might as well do it right! Also use two different colors of wire. It'll keep you from going bug-eyed trying to figure out which side is which. As for the connections you want to connect all the 4/5 connections together and all the 9's together. From here it really doesn't matter which leg you send to the power tubes. Just keep them consistent. Send 4/5 to pin 2 and send 9 to pin 7 You'll also want as tight a twist as possible on the heater wires to stop the hum. Here's where solid core wire really works like a charm! That'a about all there is to doing the heaters. That and a little patience. Hope that helps you out some and don't hesitate to ask questions. We all start somewhere. Wish I had access to someplace like this when I started out! Carl Z
