Another PreBS 15 is completed. This time it’s wearing black with a silver stripe. It features a 12″ Mojotone BV-25M speaker, Mercury Magnetics output transformer, and push-pull mid boost. Of course, it has the usual bells and whistles as well; all tube point to point wiring, choke filtering, full sized reverb tank, pull- bright on the treble pot, and a negative feedback pot on the rear panel to dial in the right amount of break up and harmonic content. 18W output from a pair of Tung-Sol 6V6s make this the perfect bedroom, rehersal, studio, and giging combo!
