Dierking QQE06/40 2m amplifier. Since a long time I had an early version of the famous “Dierking” 2m amplifier ( link) lying in my junkbox. Together with an NTR17 transformer (400-350-0-350-400 + 2×6,3) I assembled a nice and compact …
Linear amplifier with QQE06/40 tubes

The new power supply addition uses a custom made toroid. Power rating: 51VA. Primary: 0-230V @ 50Hz. Secondaries: 0-230V @ 150mA rms + 0-24V @ 500mA rms + 0-40V @ 100mA rms. The 230 volts winding is for the regulated screen voltage, the 24 volt winding is for timers and relays, the 40 volts for negative bias.

come across an amplifier using an 06-40 however most push-pull circuits: more on that later. Having decided on the 06-40, the following is a description of an amplifier that I had immense pleasure in designing and building from the ground up. It took about 2 weeks from conception to completion: a testament to the theory and the
