[ARC5] 10 meter BC-454 - Drift.

[Geoff]

All that does is somewhat stabilise for power surges but gas regulators arent that quick at times and the filament is still affected. Zeners are mo betta or just DC regulate everything with serious SS. Those are still just short term attempts where long term drift is much more annoying.

  How about just regulating the supply voltage
