Part 1 of a 3-part series on comparing different power tubes.
Warning:
Switching power tubes in a tube amp can only be done if the tube amp is correctly configured for different sets of power tubes. Do not try to exchange power tubes in a tube amp unless you have verified that the tube amp is properly configured for the new set of power tubes. Once installed, all new power tubes should be properly biased before playing the tube amp.
Power tubes can get very hot after a very short time of being turned on. Do not handle power tubes until they have sufficiently cooled down.
Do not attempt to change power tubes or bias a tube amp unless you are qualified and knowledgeable to do so. If you are not, please have a qualified technician do it for you. If you choose to exchange power tubes in your tube amp, you do so at your own risk and SonicTone Amplification is not responsible or liable for any damages or injuries that may occur.
