Conframe-modified electronic pipe audio output transformer with C-type Control ----- Vacuum Tube Output Transformer

Reconversion Electronic Tube Audio Output Transformer with C-type Control Transformer, Vacuum Tube Output Transformer Keywords: Reconfaction electronic pipe audio output transformer with C-type control transformer Change electronic pipe audio output transformer with C-type control transformers Control the transformer with C-core, modified electronic pipe audio output transformers, the quality and power of the same product audio output transformer is difficult to divide, especially in terms of clarity, intensive force, great dynamics, etc., this method does not need to be revoked Your fun may try it. I. Performance and characteristics of C-type control transformers 1. The C-core has the characteristics of large flux density, small size, light weight and one-fifth of the magnetic leakage (one-fifth of the EI type transformer). It is good for the effect of the sound device than the EI core transformer. 2. Since the C-core transformer primary 220V winding and secondary low voltage windings are split on two skeletons, and therefore, the interlayer distribution capacitance is small, and the high frequency loss is also small, and the audio output transformer is changed. With its structural advantages, the related articles can be found in 2006 (practical audio and video technology) No. 3 (using C-core production single-ended push-pull dual-use incense output transformer). Second, C-type control transformers 1. Reform single-ended output transformer Since the C-core control transformer primary winding determines the number of turns according to the AC 220V voltage 50Hz, if the working voltage of 6p1, 6p14, 6p3p is about 250V, the central frequency is output at a single-ended transformer at 4001TZ, the primary winding Do not have to be changed; if you want to change the working voltage of the work voltage such as 6N1, 6P12P, the first phase of the primary 220V two windings (central connection) can be connected, and the end is connected. The above two cases, the secondary windings (centrally disconnected) are connected to the same name (multi-tap), and due to the change to the single-ended output transformer, to prevent the core from being detached, the core is removed, pad on paper The film (thickness is shown in Table 1), this work should be carried out first, the primary secondary impedance of the transformer is the same as the C-type control transformer power size and the original calculation of the C-type control, and the value of the Value and the range of the management should be shown in Table 2. . 2. Reform push-pull output transformer This method is relatively simple, and the C-type transformer primary center connection is attached to the tap of connecting B + voltage, the secondary (central connection) is connected to the same name (ie, connected), no need to disassemble the core. See the schedule for impedance and use tube. Reform wiring diagram with reference to the drawings.
