1. Here are some tips on using tubes Do not use treatments on tube pins or in sockets If you decide to experiment with other tube types it s best not to swap tubes in and out repeatedly as you never want to cycle amplifiers on and off rapidly They should be left off for at least five minutes Further every time you insert a tube you stand a chance of loosening the tube sockets It s okay to have fun and we support that but don t go crazy and swap tubes in and out twenty times in a day Do not leave the amplifier on 24 hours a day Just a short warm up is required for the PrimaLuna to get into its groove Break in yields improvements Every tube when new needs to be left alone for a little while So when your amplifier is new or when you re tube it it may take a little time to settle in There is however no fixed time rule for break in Please note that tubes can vary electrically and by plugging in the wrong type of tube i e 6922 for a 12AX7 you can damage the amplifier and void your warranty Common replacements 12AX7 ECC83 ECC803S E83CC 7025 CV4004 You can also use a 5751 but please note that the 5751 is a lower gain tube than a 12AX7 and the sound will be altered 12AU7 ECC82 ECC802S E82CC 5814 6189 CV4003 KT 88 6550 KT 90 You may also use EL 34 6L6GC 7581A and KT66 though power will drop slightly Topview picture of ProLogue Five PrimaLuna ProLogue Five Fuse Protection A note on fu2.
