Transformer number: 906221.501 2746634.2
Primary: Black/Black Strip
Primary Tests: Black/Black Strip 2.4 ohms (242.6 millihenries). Rated for 120vac circuits.
Secondary #1: White/Yellow/White.
Secondary #1Tests: White to Yellow 7.8 ohms DC (323.2 Millihenries), White to Yellow 7.3 ohms DC (3.24.8 Millihenries), White to White 15.1 ohms DC (1.345 Henries) Secondary #1 for Output tubes.
Secondary Power Test: (Note this test performed with 120vac applied to primary and unloaded transformer voltage test on Secondary) White to Yellow = 143.5 VAC unloaded, White to Yellow = 143.5 VAC unloaded, White to White 287 VAC unloaded.
Secondary #2: Yellow Black/Yellow
Secondary #2: Tests: Yellow black/Yellow 0.2 ohms (6.54 Microhenries)
Secondary Power Test: (Note this test performed with 120vac applied to primary and unloaded transformer voltage test on Secondary) Yellow Black/Yellow 6VAC unloaded
Bolt Pattern: 75mm
NOTES: We have tested this Transformer and is in good working order. We also rung this transformers to make sure the windings are all good. All tests were performed unloaded. Peak LRC meter LCR45 used at 1kHz and Fluke 77III meter. Ringing done with our oscilloscope. We will tag the transformer with a primary secondary information.
