need special 19 set dogbone

[Bruce MacMillan]

I was about to sacrifice a regular dogbone but thought I should ask here first.

My WS19HP (Can) is restored but I need the dogbone that goes between the power supply & the amp. This looks like a regular one but is wired differently. It is also keyed at the 2 o'clock position, not the usual 4 o'clock.

Part # from the manual is Conn. 12 point C19-1.

Hopefully someone might have the piece and wonder why it wont fit a regular 19 set.

I would like to spark this baby up soon.

Wait a long...LONG time before you touch that great big capacitor smack in the middle of the power unit. It tends to hold arm tingling charge for a while. Ask me how I know.

Ah yes, the HV hand jive! Done that a couple of times. Certainly reinforces the one hand rule.

To test the psu I had to remove it from the case and bypass the interlocks. You respect 1300 vdc.

Hi Bruce,
From the bowls of the warehouse appeared a correct dog bone as you require. NOS, and correctly marked. I also have a few of the regular "4 o'clock" dog bones
PM me for details. ..... Brian

Thanks Brian, PM sent

Hi.

Can you tell me if the normal not connected points in the centre are used? I have an odd one that is at four o'clock and has extra wires in it.

regards

I have one here that is marked :

conn 12 pt ?

No. 16 or 14 ? mk 11

It has a lead coming out of one of the 6 pin connectors, the lead has a 2 pin bakelite connector on its end with ZA 12979 on it

For Peter:

On the normal Canadian MKIII plug, pins 9, 10, 11 & 12 are not used. Not sure about your key rotation. Early plugs were fixed but later shells could be rotated.

For Mike:

It sounds like you have a connector for use with the British HP amplifier. The 6 pin versions were #14 & #16 and the 12 pin version was #27. The 2 pin lead went to the socket marked "control" on the front of the amp.

Yes, that is the one Bruce . I have owned a few of the 19 set amps over the years, still have one here somewhere .

During the 1950's the Aust. army modified the 19 set amp., for use with the 122 set ( Aust) , the mod involved removing two of the 807's and fitting a meter in the front panel . A friend VK5WT had his 122 and the amp running , it put out around 50 watts carrier from memory . I did own one of those modified amps at one time .

I checked with a HP and power unit and they are indeed little different positioned than on a 19 set.

The odd one fits easily so it came with the lot of ws kit including a HP. I know now why it didn't fit a 19set + PU set up. Was just considering to make it fit.

see pictures; first one is inside with the extra wires connected in the centre and the second one with the ordinary bone.



top one in the second picture is the HP one



the odd thing is they have the same ordering number????

Connector
12 pt No 23A
(Canadian)
RCA 110076

Now the bad new I cannot sell it sorry
