Out of curiosity, why doesn't PWM sound like a good idea? There isn't really an alternative, other than lowering the current, which you don't seem too fond of either. I'd say PWM is the easier method. Just choose a sufficiently high frequency to avoid noticeable flickering. Note that the ammeter averages out readings, so whether the tube is driven at a constant reduced current or PWM, the reading will be lower, even though PWM is full current delivered in pulses. lørdag den 14. januar 2023 kl. 14.14.52 UTC+1 skrev overdoingism Lab.:
