Another transformer for which I'd like to find specs

[KE6DF]

I have a large Thordarson Driver transformer.

The part number is T-3D62.

I believe it's from a Gates BC-1E broadcast transmitter.

It's big -- probably 12 - 15 lbs.

Perhaps it would be in the Broadcast Components catalog.

The 3D62 would be in the broadcast catalog.  I have to locate the catalog.

PP 845s to PP 833s, PP 805s,  minimum grid imp 800ohms. Turns ratio (pri to 1/2 sec) 6:1.  Max Db level +36Db.  Max pri current per side 70 ma.

Thordarson gave names to their broadcast xfmrs.  The 3D62 was given the name "DIBBLE"  In 1941 the xfmr listed for $37.50  Try having one made today for $37.50.

Hope this helps,

Many a firm gave a simple, single word name to individual products to make telegram orders cost you less via word count. 

You didn't have to use a lot of words in a description to get your items, just say "2 Dibbles to wherever".

Western Union to the rescue....

Thanks DG,

Always knew the names were for ordering ease.  Never thought of the WU word count consideration.

Of course $37.50 in 1941 dollars is well over $400.00 in 2012 dollars.
