Identify transformer

[Doug]

This transformer part number 7986-167-300 with date code
7248 so 1972. Is that Magnavox type part number?
Eia code 549 midwest coil and transformer.
Looks like audio output transformer, like the ones 5 tube radio has.
Searching web simular came up as vertical blocking transformer I thought sams
Photofacts had a way to look up by part number.I did see they have it for
Ics lookup.
I don't have any other sources.
Tried searching on encompass no luck.maybe to old.
Thanks
Doug

What exactly is this in & what is its function ???
Maggy part number style is ######-##
example 703744-03 ( or just -3) is a power supply for a T991 chassis.
Also I dont think vert blocking xforms were used since the 1950's.

It's something I had.
Just trying to figure what it is.

Roger that. It does look like an audio out. Anything else wouldnt have the plug in terminals. It would probably sub any tube type class A amp of low power.
The ##s on it dont ring any bells as far as format goes. Could be in
house markings or one of the small mfgrs numbers.

Maybe Warwick or something of that time.
In house number is what I thought also
Thanks for the info

Most audio output transformers use red and blue for the primary wire color. I've seen similar looking transformers with black wires used as pilot lamp or filament supplies.

So using a audio generator input and scope output would I be able to tell if it's audio tranformer
Or ac transformer ?
Audio transformer maybe range of 50-10k
And ac power transformer limited range?
I can come up with the ratio the the gen and scope.
Might give an idea if it's 10:1 possible 12v, 20:1 possible 6v

It looks too tiny to power much of anything.

If it's a power transformer for 120V line to B+, turns ratio (Vin:Vout) might be around 1:2.

If it's a filament transformer, ratio would be around 120:6 or 120:12 (20:1 or 10:1)

Audio transformer turns ratio might be around 20:1 (Vin:Vout) but wider possibilities than a filament transformer.
The lugs seem useful for speaker connections rather than circuit connections.

It's the little power transformer used in my Magnavox T940 combo set for the turntable well lights, 6.3V at about 100ma located on the front of the TV chassis and feeds a little pop up switch. They spared no expense.
