1966 Alemite Strobe Light wheel balancer.

Transformer Identification: Model 324947, 606-545

Manufacturer Clues

• 606-545: The “606” prefix is a classic EIA (Electronic Industries Alliance) code for Woodward-Schumacher Electric (now Schumacher Electric Corp.), a well-known US transformer and power supply manufacturer.
• 324947: Likely a Schumacher internal part/model number.

Likely Application

• Based on the high-voltage secondary and simple rectification, this transformer is probably used in:
  • Tube amplifier power supplies
  • Vintage test equipment
  • Industrial control circuits
  • High-voltage DC supplies for relays or solenoids

Electrical Specifications (Inferred from Measurements)

Parameter	Measured/Observed Value	Likely Spec
Primary Voltage	230V AC (tested at 252V)	230V AC, 60Hz
Secondary 1 (Red_1)	266–272V AC	~250–270V AC
Secondary 2 (Red_2)	7–8V AC	~6–8V AC
Rectified DC Output	285–305V DC (post-capacitor)	~300V DC (unloaded/filtered)
Rectification	Single 5A8 diode (half-wave)	Half-wave rectification
Capacitors	Multiple, rated for high WVDC	Filtering, but ripple present
Brown Wire	Ground/reference (likely CT)	Center tap or ground

Datasheet or Cross-Reference

Direct datasheet for 324947, 606-545 is not available in public databases as of 2024. However, Schumacher transformers with similar numbering (606-xxx) from vintage equipment often share these characteristics:

• Primary: 230V or 115V (sometimes dual primary)
• Secondary: High-voltage winding (200–300V), low-voltage winding (6–12V), and center tap or ground reference
• Power rating: Typically 30–60VA for this size and voltage range

Next Steps for Positive ID

1. Contact Schumacher Electric with the part numbers for legacy data.
2. Compare with vintage tube amp or test equipment schematics-these often used Schumacher 606 transformers.
3. Physically inspect for additional markings (sometimes on the side or bottom).
4. Replace aging filter capacitors if ripple is excessive.
5. Oscilloscope testing for ripple and waveform confirmation.

Conclusion

Your transformer is almost certainly a Schumacher Electric (606 EIA code) unit, likely designed for high-voltage DC power supplies in tube or industrial equipment.

• Specs: 230V AC primary, ~270V/8V AC secondary, center tap or ground, half-wave rectification.
• Datasheet: Not publicly available, but specs match Schumacher’s classic high-voltage transformer line.
