Just curious. (Again, I know, sorry!)

I built a Fender style amp a few years ago and wired my heaters so that a separate twisted pair was connected between each tube. What I mean is that one twisted pair ended at the two pins and another completely separate twisted pair started at those pins and went to the next tube. This way, there were two wires (one coming, one going) to each of the two pins, totally four wires to each tube (except, of course, the last tube farthest away).

In the trinity diagrams, it looks like the twisted pair goes end to end with one of each color wire somehow sprouting out from the twist for each tube. Is that rally what's happening, or is that just a diagram artifact? Are those wires somehow spliced into the "main" twisted pair, or is that just a simplified drawing?

I hope this isn't a stupid quesiton. I'm just wondering if there aren't some special tips or techniques that I'm not aware of. If I had to do it without a diagram, I would do it the same way I did my other amp. Maybe that's ignorance on my part or maybe it's common sense.


In the photos in this thread (thanks coco) http://www.trinityamps.com/phpbb/viewtopic.php?f=7&t=752 the heater wires appear to be white and blue along the edge of the floor of the chassis. Most of the tubes are obscured just enough to not really see how many wires are comiing out, but it sort of looks like only one white and one blue are going to and from V4 and V5. On the flip side, it sure looks like two white and two blue are coming out of V2.


Also, hope this one isn't really dumb. My kit came with a ready made set of twisted wires. My initial thought was, "Cool! How convenient!" But then, I realized from the photos that there's another twisted pair riding along the top. Seems to go to the footswitch jacks for a non-kit amp, but I'm not sure yet. Just wondering what the intent of that ready made twisted pair was.


Sorry for the newb-ish questions. Warning: More may follow.

You wire the heaters just like you said. The pre twisted is for your convenience. Cut it to length, strip ends and solder as you said. If you need more twisted, cut two different colours to the same length. Put the ends in a drill, hold or fasten the other end and use the drill at low speed to twist your wire into a tight twist.

No such thing as stupid questions if you don't understand or know. Its how we learn.

Thanks for the confirmation. It seemed kind of crazy that there'd be some weired wire stripping and splicing in, particularly with any wires to or from the tubes. But I just thought that maybe there was something I didn't know. Glad to hear that the right way to do it is the way I did it before!


And geez, talk about convenient! Trinity actually bothers to pre-twist a pair of wires for the kit. Cool!

I was once told: "There are no stupid questions, only stupid answers." Mind you, that same college prof was famous for another thing. You asked regarding how to calculate impedence, and he would answer "Chicago, Illinois!" It was his way of saying: "There is no such thing as a stupid question, but you are asking the wrong question. Ask a different question, it might be the right question to ask."
