How to identify Filtertrons, old or reissue?
hi there, i bought recently a 1967 double annie which is equipped with filtertrons. as far as i know the pu's must be replacements cause at this time annies had only hilotrons. does anybody has an idea how to identify if the filtertrons are old ones or reissues, the covers look the same. i'm not very happy with the sound and think about upgrading to tv jones classics, but first i need to know something about the installed pu's. thanks in advance tosca
