Like any other transformer, audio transformer comprises of a primary winding, secondary winding and the core and the primary function of an audio transformer is to couple the energy from the primary windings to the …

Example a.) shows a centre tapped secondary winding that can be used to provide a selection of different turns ratios. Some transformers may also have tapped primaries for an even wider range of ratios. In audio amplifiers, the phase/anti …

Rewinding audio coupling transformers Interstage audio transformers are the most unreliable component encountered in the repair and restoration of early radio equipment. Used in practically every pre-1930 radio, their mortality rate from corroded windings was extremely high, and few receivers will be found with their original transformers intact.
Audio Transformer, its Types and Impedance Ratio

Audio Transformer A Transformer receives a sinusoidal input signal and converts it to an output signal. During this conversion process, there are no physical connections between this two. This conversion actually happens by the two or more insulated copper wire coils (which are denoted as windings) wrapped around a magnetic iron core.

outer secondary or voice coil winding will be uncovered. Unwind this wire, noting the number of turns, typically somewhere between 50 and 100. Underneath a layer of insulation will be the primary, consisting of several thousand turns of fine wire. Counting them would be a tedious business, likely to put anyone off transformer winding forever.

Transformers always reflect impedances from one winding to another by the square of the their turns ratio or, expressed as a formula: Zp/Zs = (Np/Ns)2 where Zp is primary impedance, Zs is secondary impedance, and Np/Ns is turns ratio (which is the same as the voltage ratio).

By using the above formula, we can calculate the turn number of windings required. It is proportional to the ratio of input and output impedances: n=Np/Ns=(Zp/Zs)1/2 where Np and Ns designate the primary and secondary turn numbers. n=(4096/4)1/2= 32; The equivalent transformer impedance can be then calculated (tube impedance is 5 kOhm and Zp is

The reason for this is that here in S Africa the price of proper audio transformers are incredible and there is no real place here that specializes in audio transformer winding. Market is too small I guess.
