Oh Dear! This item has been sold but take a look around for other similar items

As removed from a PIONEER Sub Woofer

Relatively recent equipment (1990's most likely) but I didn't record the model number this came from.

Absolutely perfect as a replacement transformer (of the same type) in Pioneer equipment or use this as the basis for AC power in a custom amplifier project.

 

PIONEER Sub Woofer (SPARE PART ONLY)

Manufacturer is unknown, SF within a diamond shape

Part number is: SF-76E/262037

Internal heat overload (thermal) fuse protection built-in

240V AC input (brown-blue)

Output voltages measured under NO LOAD

27.7 - 0 - 27.7 AC output (yellow-white-yellow)

Single secondary winding so if only yellow-yellow is used, AC output is measured as 55.8V

Estimated current capability is around 1A across the full secondary (~50V roughly under load)

 

Great for powering a low power dual channel audio amplifier.

 

COSMETIC CONDITION:

There is no physical damage to the transformer or the leads

All leads are 250mm minimum length, multi-strand conductors.

Physical dimensions: 65mm height x 78mm wide x 85mm front to back

Windings occupy a space of  75mm x 50mm x 40mm

Core uses E style laminations

Solid frame construction - no risk of transformer "buzz"

Mounting is via 4x base holes, two of which have nuts already riveted on them. No screws/bolts are supplied

Weight is 2.3Kg

 

TESTING:

The transformer was voltage checked once removed from the equipment, results are above.

The current capability is only an estimate and personally I feel that I am being quite conservative on this and the transformer could well be capable of higher currents.

From memory the sub woofer it came from was rated to provide up to 100W bass although to link this with the AC transformer rating is a pretty low bow, but it gives the impression that it should be capable of providing 1.5A or perhaps even 2A at the secondary(s)

Stored safely in sealed plastic.
