Wiring clarification + Turret Board Connections
Hi All
While fixing my first amp built that has some issues I am thinking for next build.
I have removed on my first amp all tube sockets since the issue was there and restarting all that part from scratch
That being said my questions
For the new build
1) Stranded tinned wire silicon
2) Or solid tinned Silicon
Stranded are a little more difficult to solder at least for me.
Size is clear 18 awg heater wire rest can be 20 or 22
On the turret board , see layout there is some sort of wire that connects externally some turrets
I am not sure how technically that is called a bus wire maybe?
It is solid tinned or at least it seems so how is called since I need to get this?
Thanks

Re: Wiring clarification + Turret Board Connections
Don't use 18AWG for heaters. Use 20 to 22AWG. 18AWG is too thick and a PITA. I only use 18AWG for the power transformer connections to the IEC socket, earth from IEC socket, and PT switches.
Solid or stranded is fine, but stranded is less likely to break. Stranded should be pre-tinned and bonded prior to making soldering connections. Watch the soldering videos again, they show how to do this correctly.
Thanks,
Josh

Re: Wiring clarification + Turret Board Connections
Those yellow wires connecting the turrets are jumper wires. You should do those on the top side so you can check and adjust afterwards. I use 0.5mm tinned solid wire and cover them with heat shrink between the turrets.
Here is an example: And as Josh said... NO 18 AWG for heaters. 22 is just fine and a lot easier to manipulate. The heater wiring is the hardest part of all wiring in the amp and should be done close to perfection. You don't wanna have doubts on those when your entire amp is wired. They should be very rigid when assembled. Again.. use heat shrink. Here, not the worlds best example.. but this is the idea :

Re: Wiring clarification + Turret Board Connections
I meant precisely the silver metal wire running externally along the edge of the turret board see photo
for what you said before it is fine I got you
It is also a jumper wire but as I can see is a tick bare wire isn't?
It is soldered under the board isn't so that is a tinned solid bare wire correct?
Pardon me if I am asking again

Re: Wiring clarification + Turret Board Connections
That's called a bus wire. the modern ground schemes in my signature to make sure you do it correctly.

Exactly bus wire thanks again tomorrow I’ll a look once more all videos + modern ground scheme to be honest I’m looking at it every dayJMPGuitars wrote: ↑Sat 04/17/21 4:19 pmThat's called a bus wire. the modern ground schemes in my signature to make sure you do it correctly.

I done basic electronics training and I’m going through an amp course I found online
I am seriously interested really am

Re: Wiring clarification + Turret Board Connections
Speaking of bus wire, I just discovered that none of my usual suppliers have anything larger than 20 ga now. I have a small hank of 14 ga left, but I'll need more soon. Is anyone in the US still selling 5-10' lengths of the larger wire?

Re: Wiring clarification + Turret Board Connections
Hi all
That was one of point why I rose the question
Finding the right size tube-town doesn’t seem to have it same tonefactory or Banzai
However at local hardware store they have 14 ga solid but insulated wire if removing the insulation the result is the same robust bus wire , in other words that is bare wire however don’t know if the is tinned wire need to double check
Thanks

Re: Wiring clarification + Turret Board Connections
After more searching, Jameco has 100' spools of 16 ga for $18 (less expensive than Tube Depot if you can use that much). I found another place with 25' minimums selling 16 ga for $0.24/ft, 10 ga for $0.60/ft. and 6 ga (!) for $0.90/ft. 14 ga is really the most useful size, but they're out of that. I wonder if there's a shortage due to the pandemic? I don't remember having problems finding this a few years ago.

Sure they do at tube town. Here, this one is real thick. This is the one I use.davemojo wrote: ↑Sun 04/18/21 1:02 amHi all

isn't too thick is?
I think i like to follow up with that Tubetown project layout doesn't seem too bad is?

Re: Wiring clarification + Turret Board Connections
Hey folks
When looking at this, see photo, there are mainly 2 to 3 ways when soldering turret board.
for components such resistors we could feed the turret with solder, so from the top.
another method is to create a little hook on the resistor to create a solid connection and to solder the side of the turret between the hook and the turret itself. I watched Josh videos, the old vintage video explaining all different method , fantastic today I was able to train myself on a broken turret board, perfect for simulation and practice.
I also have a question, if you check the wire connections coming from pots, gray wire, on the photo example I see a clean job with wire solder under the turret.
Now to be able to do that you must put the turret upside down, but that isn't practicle and even possible, so how would that wire be soldered underneath turret, the only way I see it is you prepare that in advance before connecting the turret to chassis and even before adding components, correct?

Re: Wiring clarification + Turret Board Connections
Dave... forget about soldering the underside. Only top side soldering. You don't wanna have trouble when you have to resolder connections when everything is soldered. Try to avoid soldering in the holes of the turrets. Use hooked wires around the turrets. Much easier to redo. The holes in the turrets are a mess and there is little control over it when the solder drips underneath, making shorts between the turrets and chassis. I myself try to only use the holes for the ground bus.davemojo wrote: ↑Sun 04/18/21 10:23 amHey folks

Try soldering the holes.. there is always some goo coming out of it when soldering
Here is my 18W tremolo TMB reverb.. some kind of example on this. Not perfect, but it gives you the idea :
