Hallo,
have a question regards power tubes used in Bassman 100 from 70-73 era,please. I just remark this series from those years used a quad RCA power tubes with 2 short bulbs and 2 long bulbs like the pics show. From begining I thought it was a sort of factory mistake but if you look at bassman 100 amps from this era will see is a current factory practice which was assumed from whatever reasons they have. Did someone know from what reasons they used for , please? Thank You.
Best Regards
Catalin
