Good morning everyones. I would like to have the wiring diagram or wiring instruction on my audio output transformer Peerless S-265-Q. Please help me on this.
Thanks

I don't have a pin-out diagram, but I do have a Peerless cataloge listing the specifications. Using an ohmmeter, and logical deduction, you should be able to figure out the terminal connections from the specs.
There are two seperate center tapped primaries which may be used in series or parallel to yield 10,000 ohms CT or 2500 ohms CT. Max balanced current is 110 mA or 220mA respectively. And Max unbalanced is 11 or 22mA. (Each individual primary is 5K CT)
Secondary values are 2, 4, 8, 16 ohms and may be operated with one end grounded. Max operating level is +46dbm or 40 watts.
Once you figure the general connections you can use low voltage AC and a voltmeter or scope to determine the phasing of the windings.
Also, I'm not positive on this, but I think you must always use both primaries at once or the transformer will be unbalanced.
Hope this is of some help to ya.

hey-Hey!!!,
As you look at the bottom of the can, with the secondary connections in line up and down connect the middle two and take output at 16R from the top and bottom ones. For 8R, connect the ones next to the top and next to the bottom and take output from the upper and lower tabs. For 4R you put them in parallel, lower middle to the top and upper middle to the bottom and take output between uppermost and upper middle.
If you want to know how the bobbin is wound, I can tell you that also as I took one down, turn-by-turn and made copies...🙂
cheers,
Douglas
