Rewinding output transformers A frequently encountered problem in servicing valve radios is that of open-circuited audio trans- former windings. Suitable replacements are hard to find, creating a serious problem in restoration projects. This month, we describe a practical method of using simple tools to rewind speaker transformers.

When winding OP-transformers, keeping parasitic inductance and stray capacitance at low values is a good thing. If there's room to spare inside the lamination window, adding extra layers of insulation would help lessen stray capacitance between layers. -Would this also result in less coupling...

Line Output. Typically, audio transformer is driven by an amplifier and loaded by several thousand pF cable capacitance and high input impedance of line receiver. Therefore, a line output transformer should have low output impedance which remains low at high frequencies. This requires both low resistance windings and very low leakage inductance. 5.

In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

The amplified audio from the 2 output valves, push pull is in opposite phase 180deg. 300VAC + 300VAC = 600V AC is across the primary winding. Depending on the tranny design there may be 2,000 turns of wire in the Primary and 90 turns for the Secondary winding. 22:1 step down ratio. 600V AC / 22 = 27V AC into an 8&Omega speaker is 90 Watts.
