Where can I find these?

Hello all,

I am in the process of putting together my EL34SET. I have been trying to find some Belden Shielded Twisted Pair wire for my DC heater wiring. I checked out Mouser and their only see in bulk: minimum amount is somewhere between 100 to 200 dollars for 100ft or so. Angela and Vintage tube audio dont seem to have them either. So where online can I buy some good quality STP wire for around 20 to 30 dollars? I just need about 15ft or so. Thanks🙂
 
I assume you mean the heavier gauge stuff, like the stuff in industrial control systems. You can buy that at an electrical supply house, the kind electricians go to. Look in your Yellow Pages.

You can buy the thin stuff at your home store as networking or telephone cable. Just ignore the extra pairs, or twist multiples in parallel.

Now comes the BUT...why STP for a DC heater? If it is DC, just take 2 lengths of hookup wire and twist them. The shield serves no purpose.
 
I in doubt about utility of twisted wire for DC filaments !?!
But anyway it's very easy to twist them, here's the trick :
hook the wire pair (or more) in-between a clamp and a drill's chuck.
Then use the drill !

Hope this helps.
 
hi guys,

I was looking for some shielded twisted pair not only for the DC heater supplies buy also for the input connections and speaker connections as well. I guess with DC heater supples I don't really need STP's but I thought I might use them as well for extra precaution!
 
Hey scott_m which one did you specifically buy from this list? Was it the the 8450 or the 8451? Also it says that the 8451 is STP but is the 8450 also STP?

EC8010 I would prefer buying them but if I don't find what I want i'll probably do it your way!
 
I have stock on some 1 cond 16 Awg Shielded Teflon silver
Plated using the shield as a conductor will get you your 2
conductor. Also some 4 conductor I think 18 or 20 Awg
also silver plated shielded teflon wire. Twist them too.
If you want smaller I have reguler teflon wire in gauges from
26 Awg to 8 Awg. Prices are on my website under wire
