so 12AX7 tubes are the same as ECC83 tubes. so when marshall say they use ECC83 and mesa boogie use 12AX7 they are the same thing

12ax7 is the US designation, ECC83 is the European designation, for the same type of tube. Just like EL84's are the same type as 6BQ5's. Here is a sight where you can look up any tube, and it will tell you all names for simalar tubes, and what are direct replacements. http://tdsl.duncanamps.com/tubesearch.php
