500 Series: Guide to Effects

The Space Heater 500 from Radial Engineering is a tube overdrive 500 series module for use with 500 series power racks such as the Radial Workhorse. This module offers a single channel of natural tube crunch for adding character to your mix for use on drums, voice, bass, acoustic guitar, and more.

The Space Heater 500 uses a 12AX7 tube, and features a 3-position HEAT switch that enables the user to choose between 35 volts, 70 volts or 140 volts for the desired level of tube distortion. Distortion can be further adjusted using the combination of a drive control, plus a level control for make-up gain. The plate voltage is generated by an internal charge pump, while the Workhorse or other 500 series 16V supply provides the necessary voltage to the 12AX7 tube.

Jensen Output Transformer

A Jensen transformer is employed at the output to bring a more vintage character to the signal path while benefiting with galvanic isolation to reduce hum and buzz caused by ground loops

HPF & LPF

To further refine the sonic response, the Space Heater 500 is equipped with both high pass and low pass filters. These allow the engineer to focus the tube effect on a particular frequency band or spread it out as needed. The EQ can also be applied to the signal path either pre or post tube for even greater tonal flexibility

Power Allocation Switch

As the Space Heater 500 employs a high voltage tube circuit with a current draw of 235 milliamps, a power allocation switch adjacent to the card edge connector is available to balance the draw for use with most 500 series racks

Steel Enclosure

The steel enclosure not only protects the sensitive electronics but also helps prevent outside radiation from causing noise, or from the Space Heater creating buzz due to the high voltage required by the 12AX7 tube
