Altec 1592A Mixer Output Transformer

[CJ]

Got this in the mail, thanks!

Looks like a pentafillar wound coil on a sq stack of 375 EI

So of course 1:1 ratio primary to secondary

1:1 ratio primary to feedback

5 strands of 34 AWG
0.007" red and green, scatterwound at the same time,

PRI DCR 30 ohms each coil

Green former and lead plate all as one, indicates Peerless

PRI Ind 12 Henrys at 50 Hz (one PRI)

Saturation at about 6 Vrms
(1 PRI)
Looks like an easy rewind if I can get the core apart.

Pentafillar wound means no worries about phase between primary and tertiary winding, the capacitance is high but balanced. Similar to API output.

Pics and print coming up...

some pics of the Altec transformer,

they used an epoxy so the lams could not be taken out without destruction, no matter how hot,

and that former will melt if you get it real hot,

but now i can get the turns,
