Home Tube DIY Asylum

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

I prefer a coupling cap to a cathode bypass cap

The problem with direct coupling is that you commonly end up using a cathode bypass cap on the second stage because of the larger cathode resistor.

Because I use DHTs like 26, 01A and 4P1L which can all be used in filament bias with no cathode bypass cap, I prefer using a small teflon coupling cap (or an interstage) to a large cathode bypass cap - however fancy it is.

As said, there's no free lunch. A cathode bypass capacitor is a capacitor, period.
