Home Tube DIY Asylum

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

No need for Hexfreds

Schottky diodes are much quieter than Hexfreds and are available in low voltage, high-current versions, exactly what you need for filaments / heaters.
Digi-Key has lots of Schottky diodes, I suggest that you buy 100V parts that can stand two to three times the filament current.
For example 31DQ10 is a 3A 100V Schottky that sounds super quiet on tube preamps.
good luck
