Which there have other a few components. In an OTL amplifier a large amount of negative feedback is required to force the push and the pull to work together properly in order to provide sufficient damping for the speaker. Introduced in 1959 the ST-70 is the worlds most prolific stand alone amplifier with over 300000 units manufactured.
IC-LM741 is a normal Op-amp IC. In short the top and bottom output tubes cannot see the same magnitude of input signal save for the special case of when the output stage is driving a near-zero-ohm load. Using 2N3055 is the main component.
