Is there a way to make a 306 ring?

[newskeeto]

I just purchased a telephone that I thought was a 302.  When I opened it up, I noticed it had a strange tube that I have never seen inside a 302.  It turns out it is a 306.  I have tried to make it ring, but everything that I have tried has not worked.  Is there anything I can do?

Quick question, is a 306 the type where you can turn the ringer off or the 304?

What's the specialty of this one?

Thanks!!

You're thinking of a 305.

What kind of line do you have?

There are 2 ways to make this ring on a land line:

(1) Disconnect all 3 tube leads and add a 1.0 uf capacitor in series with the B3A ringer:
Red ringer wire to L1
Black ringer wire to K
1 capacitor lead to K
other capacitor lead to L2Y


OR
(2) Use the tube but change the wiring:

Line cord: Red (-) to L1, Green (+) to Y/L2

Ringer: Red to L1, Black to K

Tube: Yellow to L2, Red to K, Black to K  [EDIT: RED TO L1]

If you have VOIP, it probably won't work with the 2nd method.

Ah, okay, thanks!

I am using an xlink box.  I am pretty sure I am going to have to use the first method for that reason as well as the fact that I am 99% sure the tube is shot because there is something rattling around inside of it.

Two questions.

I tried the configuration shown below with no luck. Dial tone but no ring. Anyone have anything else I can try?

Line cord: Red (-) to L1, Green (+) to Y/L2
Ringer: Red to L1, Black to K
Tube: Yellow to L2, Red to K, Black to K

I swapped a B3A ringer with a 101A resonator into my test mule 302, replacing the B1AL ringer that came with it. It seemed to work fine. I love the sound and would like to install the B3A ringer into my 'daily driver' in the kitchen.

Is this a bad idea? 

[poplar1]

Did you try removing the tube and just using a 1.0 capacitor?

I don't think the connections I gave for using a tube are correct. Does anyone else have a 306 that is ringing with a tube, and obviously not on a 4-party line?

[zaphod01]

I downloaded some info from TCI and need to do some more research.

I haven't given up on it. I think I'll leave it with the tube and live with it not ringing if I can't sort it out. It just looks so cool!

CORRECTION: RED TUBE TO L1 --NOT K.

See Kenny C's diagram posted here: (original post)

Thanks! I'll give it a shot in the morning!

Attention: 3rd shift and West Coast members: Anyone have a working 306 or 501 set, still using a cold cathode tube with the ringer?

[poplar1]

I finally got this to work by using Kenny's diagram but reversing the incoming line. I apologize for the faux départs.

This circuit is polarity sensitive. (I connected a 1500DM set with no polarity guard to make sure the test jack was poled correctly.)

Incoming line: red (-) to L2 and  green  (+) to L1.
Ringer :  red to L1 and black to K.
Tube:  red to L1, black to K, yellow to L2Y.

If you would rather have the incoming line red to L1 and green to L2Y:
Then ringer: red to L2Y and black to K.
Then tube: red to L2Y, black to K and yellow to L1.

Either way, the two red wires (ringer and tube) connect to the same terminal, and the two black wires (ringer and tube) connect to the same terminal.

I would sleep a lot better if someone would tell me that they tried this and it worked, or has an alternative way of making a ringer work with a tube.

My problem with these is that I have phone service through my cable co using an ATA at 24 volts which isnt quite enough DC bias.  My 501 ringer will barely wiggle.

Bill, do you have a Panasonic 616 KSU? The 306 rings fine on my Panasonic if ringer is set on low bias.
