Randall RG50TC - Normal preset
Verified · 87/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.
The Randall RG50TC is a 50-watt, two-channel all-tube combo amplifier that blends Randall's signature high-gain character with the warmth and touch sensitivity of a tube power section. A more compact and manageable alternative to Randall's 100-watt heads, it found favor with studio players and smaller-venue performers who wanted the Randall high-gain tone at practical volumes. The RG50TC demonstrated Randall's ability to deliver boutique-quality tube tone at an accessible price point.
