What is the best way to heat a 300b with dc?
i read on the EML website no current sources
so no tent labs heater modulles i normally use
But wat is a nice and good sounding way to do it then ?
i now ac sounds best but sometimes speakers are so sensitive that dc is the only way

Hi,
A simple way is to use a switching power supply like Mean Well 5V/7A. Small, easy to adjust, and stable.

The best way is with a Tentlabs module. This regulates and stabilize the DC. Beautiful sound scheme and safe for your tubes.

Rgrds ,Bart.
