I decided to make a tube only RIAA phono stage and make a nice over the top PCB for it. The design is a bit based on the Luxman EQ 500 with less bell and whistles, but in basic form the

The DC/DC uses a half-bridge circuit to provide a stable DC bus voltage and isolate the input stage and the output stage. The inverter part adopts a conventional full-bridge inverter circuit, which is suitable

The higher voltage supplies large loads such as traction motor, air-conditioning, and starters. Lower-power components such as infotainment and safety systems will remain on 12V supplies.

In my next amp I want to try an interstage transformer for the phase inverter. Any suggestions on transformer and implementation? It will be a 100w guitar amp (quad of 6l6 or el34,

For example, it is necessary to design a high frequency modified square wave inverter with an input of 12V, a variation range of 10.5-15V, and an output voltage of 220V 50Hz.

Most of the classic amps use feedback around the output stage, from speaker to the phase inverter (or the stage ahead of the inverter in a split-load circuit). The feedback acts to

This phase inverter requires the use of a full traditional preamp tube, two complete triodes. This provides one triode to deliver each half of the split signal, with a more complex network

Safe, robust, efficient switching of the power transistors within the power inverter is an important function of the gate drivers within a VSD. The next blog will consider some of the signals

Therefore, an additional tube stage called a “Driver” is used ahead of it. The Driver provides the gain, the Cathodyne inverter provides the necessary phase-flip, and they both live as a happy family.
