Using Dynaclone Mark III transformers achieves a closer replication of the original Model T's power and tone characteristics than Weber transformers.

Some owners have modified the Sunn 100S by replacing the "external speaker" jack with an impedance selector switch to access 4, 8, and 16 ohm taps without drilling.

The Sunn 100S has a unique tonal difference due to its use of a pentode in the pre-phase inverter, unlike the Model T, impacting gain characteristics.

The 1967 Sunn 100S shares its output jack setup with other Sunn models from the era, like the 1970 Sceptre, offering similar versatility.

The Sunn 100S originally came with dual KT88s for output, but some revisions used 6550s and were advertised at 60 watts.

Unlike the Model T, the Sunn 100S includes tremolo and reverb features, adding versatility for different musical styles.

The Sunn 100S's "speaker" jack is designed for 8 ohm loads, while the "external speaker" jack accommodates 4 ohm loads.

Owners can connect two 8 ohm cabinets by using both the "speaker" and "external speaker" jacks simultaneously.

The Sunn 100S can achieve doom metal tones effectively, especially when paired with a quality fuzz or distortion pedal and high-output pickups.
