Thank you Alfred, One must be careful in considering replacement tubes. In particular tye GZ34 has a lower heater current than many others of a similar HT rating. It may be OK for that amplifier but not for all! The attached pdf gives a brief overview, but other factors such as series resistance and capacitor loading must also be considered. Best regards,Roy
