Randall RD100H Diavlo 3-Channel 100-Watt all-tube guitar amplifier head with matching 4-button Randall footswitch.

This is the full-size 100-watt model from Randall’s Diavlo series: a high-gain, three-channel all-tube head built around 12AX7 preamp tubes and 6L6 power tubes. It is designed around a straightforward Clean / Gain 1 / Gain 2 architecture, with an additional switchable tube Boost for pushing the higher-gain sounds further. Randall specifies 100 watts, three channels, 12AX7/6L6 tube operation and 4, 8 and 16-ohm speaker compatibility.

The amp was previously noted as having recently replaced tubes and having been checked by a professional workshop.

The rear panel is unusually well equipped for a straightforward tube head. It has three speaker outputs with selectable 4 / 8 / 16-ohm impedance, a Class A discrete instrument-level effects loop, speaker-emulated balanced XLR output with ground lift, and the dedicated footswitch connection.

The speaker-emulated XLR output makes the RD100H useful beyond a conventional head-and-cabinet setup, providing a direct output option for recording or connection to suitable external equipment. The effects-loop return can also serve as a power-amp input when using an external preamp.

Includes the matching Randall four-button footswitch shown in the photos, providing dedicated switching for CH1 Clean, CH2 Gain, CH3 Gain 2 and Boost. Randall identifies the original RD100H footswitch as the RF4CHB 3-channel + Boost controller.

Please review all photos carefully. They show the actual amplifier head, tubes, front controls, rear connections, speaker outputs, effects loop, XLR speaker-emulated output, chassis, cosmetic wear and included footswitch.
