Univox U-150RX - Main preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Univox 150RX is a solid-state combo from Univox's later catalog, producing approximately 150 watts and targeting professional players who needed high-output amplification for large venues. Its solid-state circuit retains British-influenced EQ voicing with a presence-forward character despite the transistorized output stage, reflecting Matsumoku's efforts to maintain the brand's tonal identity in the solid-state era. The 150RX includes a built-in reverb unit and multiple input channels with independent level and tone controls. It is one of the more powerful solid-state Univox models and demonstrates the brand's range beyond the earlier tube-based numbered series.
