Does anyone have any information on this Chicago Driver Transformer, P/N 14424? I have scrubbed the web with no results. Here are a few pics... Thanks, Title: Re: Chicago Driver Transformer - 14424 Post by: wa3dsp on March 07, 2013, 01:11:29 PM Apparently that question came up before but it does not look like it was resolved. Perhaps you can contact the original poster.

I sent him a PM about it. Thanks, Title: Re: Chicago Driver Transformer - 14424 Post by: KB3DKS on March 08, 2013, 10:17:50 AM That looks like a Gates part #. See if anyone has the BC1-F parts list or schematic.
Probably from around that period or earlier. Driver for a pair of 845s. Bill Title: Re: Chicago Driver Transformer - 14424 Post by: Opcom on May 01, 2016, 10:14:20 PM when it rains.. I got the same type 14424 transformer handed to me today. It seems like it's enough to drive 833s and more, but still no new search provides any answer.

You have the turns ratio stamped on the nameplate. That's all you really need to know. The ratio of driver xfmrs are usually stated as primary to 1/2 secondary. The xfmr looks big enough to handle some power, probably more than you'll need for amateur service.

I'm starting to wonder if any piece of gear ever used 3-500Zs for audio with transformer coupled grids. On the bright side - good to know what it is for. Somehow I'm not surprised at who knew the real application data! 8-) |
