SST-108

The original 108 output transformer was standard fitment on several different amplifiers in Fender's catalog during the late 1950s. This includes the Harvard (some of them), Tremolux, Vibrolux, and of course the Deluxe amps ranging from around 1957 till sometime during 1959. It's an odd design for Leo Fender to pull out of a catalog for a push-pull amplifier at the time - a decision most likely due to Triad's ability to produce them in great numbers and the low cost offered to OEM manufacturers back in the day. What's unique in it's design is what makes it unique in it's sound. First unlike any other transformer Fender had used on their Deluxe amplifiers previously, it's wound on a plastic bobbin with a random wound primary. This technique reduces leakage inductance in the primary opening up the top end more from the earlier layer wound 1839 (later Triad 50246, 246) used on the Deluxe amplifier at the cost of higher winding capacitance. Secondly, it's laminated with a shimmed b
