Alex Moglia & Andy used for 01A & 26 preamps
The 26 has about 1 ampere in the cathode in filament bias, not mA.
Are the diodes parallel???

26 runs 6mA, 1A is for heaters.
For Itch is cathode bias not filament bias.
Ale Moglia: The do operate well from low currents and impact on the increase of Rds is minimal. Running them at low currents (e.g 3-4mA for a 01a stage) provides no measurable additional distortion due to the lower operating point in the knee.
