I am trying to build a 18w amplifier based on this schematic however my power transformer doesn't have a center tap on the secondary winding
Is it possible to use this power transformer for this project? I also tried it using a solid state rectifier (the one with 4 pins: - AC AC +) connecting the ac to the transformer the (-) to ground and the (+) to the standby switch (please see the schema), although I could measure the correct voltage on the (+), there was no current going on the grids of the tubes, not even on the filtering capacitors.
or maybe the problem is somewhere else in the circuit? appreciate your help
