Vintage Sparton 968 10\" Field Coil Speaker C-2280-45 w/ OT Tested For Sale

The Sparks-Withington Co. – Jackson, Michigan U.S.A.
C-2280-45

Includes the original attached output transformer, wiring and 3-pin plug.

Bench testing performed:

• Cone moves smoothly and quietly by hand with no detectable voice-coil rubbing or scraping
• Voice coil has continuity and measures approximately 0.3–0.4 Ω DC, corrected for meter-lead resistance
• Output-transformer primary has continuity and measures approximately 487 Ω DC
• Output-transformer secondary has continuity and measures approximately 0.3 Ω DC
• Field-coil winding has continuity and measures approximately 840 Ω DC
• Approximately 1.323 kΩ measured across the combined series circuit at the outside plug pins, consistent with the individual winding measurements
• All plug connections checked against the metal speaker frame with no shorts to frame detected

Speaker has not been energized or audio-tested, so it is being sold based on the electrical continuity/resistance and mechanical tests described above rather than represented as fully tested under operating conditions.

Condition: Original vintage speaker with age-related wear. The cone has a previous patch, clearly shown in the photographs. Despite the repairs, the cone remains mechanically free and moves smoothly without detectable voice-coil rubbing.

Approximately 10 inches diameter and 5.75 lb.

Includes 13\" diameter round mounting frame.

Original Sparton identification label is intact and displays well. Please review photographs carefully for cone condition, previous repairs, wiring, plug and overall cosmetic condition.
