Do It Yourself (DIY) paradise for tube and SET project builders.

Dennis Had Power Supply Design Background

Close to LSES, but likely violates your low DCR rule with the second choke. On the other hand the current demand from the power supply is low.

Dennis Had started in the electronics business with a company called Dentron, then followed up with Amp Supply Company. These businesses built RF linear amplifiers and antenna tuners (Dentron) for ham radio operators. The amplifier designs are fine products. However, Dennis did not follow that 2.5 PIV times the operating voltage rule regarding the diodes in the power supply in some products. Although failures were minimal, the later designs did raise the bridge rectifier PIV ratings.

As you know Cary Audio Design violated tube manufactures recommended maximum capacitance specifications using tube rectifiers in a CLC or CRC filter circuit. So, it is fair to state it appears a learning curve has been completed by Dennis Had.

Dennis Had designs resulted in a substantial impact with hobbyists in the ham radio and audio industry.
