Hello Bill,

Oldest mag found so far is 1995 - one still intact.
Unfortunately it does not have a M-2480 in it but has a similar one M-1100

Audio Line Transformer
Ideal for most PA-BGM applications.
Suits all speaker impedances.
Multi-tapped for use with 100v and 70v lines.
Rated - 4watts
Primary - 2.5k, 5k ohms 
Output Windings 2,4,8,16 ohms
Dim 35x62x37 mm

Picture is typical of standard audio transformer with the 2 bolt hole lugs at the bottom and solder tags for the terminals.
Hope that has helped - can send a picture if you wish but hope someone else has the real thing.

Dear gentle folk,

Does anyone have an old (real old) Dick Smith catalogue? You know, the ones that used to have real information in them!!

I have a couple of transformers, which I'm pretty sure are 70V/ 100V / 8Ω.  The stock item number is M-2480.
The 8Ω side is obvious, but there are 3 wires on the HV side, so not sure exactly how its configured!!
