Audio Output TransformerNOTE: We also sell a higher impedance (2.5 - 20K) version of this transformer, see our other listings.Limited stock item - can NOT be restocked!

This is a hard to find, audio output line transformer, and can be a good replacement for suitable 5-tube vacuum tube radios, see photos. Also a great transformer to use in vacuum tube audio amplifier kit designs and experimentation.

These were removed from UN-used equipment, and are in perfect working order. May have some discoloration on the frame.

Twenty five volt line transformer (as in PA - Public Address audio amplifier, not AC power line transformer), which makes a good general purpose audio output transformer, see photo for a typical application.

Primary has 4 taps. With an 8 ohm load on the secondary, and using a voltage ratio test, we measured the primary impedances as approximately 3,000 ohms, 1,500 ohms, 600 ohms and 300 ohms. This corresponds to a 6 thru 19 turns ratio. Verify this is suitable for your radio or application.

Nominal resistance of primary taps are 67, 44, 30 and 20 ohms. Secondary resistance is approximately 0.6 ohms.

Nominal size: 1.45" x 1.10" x 1.25" (LxWxH). 1.75" between mounting hole centers.
