Different 202 D1 Wiring

I picked up a painted D1 on FB for $20.

It was wired to work without a subset, but I had never seen a 202 wired this way. It does work!

I know it does need a subset  8)

Perfect E1

It had a gold paint that was scratched but looked professionally done. I had most off when I noticed it was gray underneath, primer? Alas, I could not save it so it is being completely stripped....Doug

If you have ever stripped a 202, they are not easy. I vowed I would never do another.   ;)

This guy was very easy, no corrosion at all! I do wish I could have kept the gray primer as it looked great, but this is a very satisfying second place. Nice buffalo nickel type shine.

Added an F1 as is sounds better.

With this wiring you can hear the dialing across the handset, but it seems to work fine as it can without a subset....Doug

Nice work!
clean base too :)
I would get a sub on it soon.
Those series sets are supposed to be hard on the elements???
not sure, gettin old.
Need to find info on the reason the sub is needed.
read it, liked it, forgot it...
Seems to be happening more now.
Can anyone point to the info on why they need a subset?

1. Subset prevents DC in the receiver, unlike hotwired phone (damage to receiver)
2. Without subset, you experience acoustic shock (in the ear) when hanging up (damage to ear)
3. Subset has ringer so you know when someone is calling

And I might add, "guards against the dial contacts welding themselves together".

How is that achieved in the typical American circuits? Euro phones often have a small capacitor in parallel with the pulse contacts, or the ringer capacitor in series with a resistor, to suppress arcing.
In American circuits a winding of the induction coil is permanently in series with the pulse contacts. Will it act in the same way, suppress arcing?

In a WE 500 set (425B or 425E network), there is a capacitor in series with a resistor, in parallel with the dial pulsing contacts (terminals F and RR).

That'll be badly then. Sorry Doug but this needs a subset, no ifs no buts.

Doug Rose

Folks... I was just asking about the way it was wired when found. It was found this way, I did not do it.

I am well aware that a subset is needed for this and a stick.
