Randall produced the RD100HE-U Divalo as a three-channel, 100-watt tube amplifier head within its Divalo series. It was designed to serve guitarists requiring distinct channel voicings across a single unit, with each of the three channels carrying independent Volume and Gain controls alongside a shared EQ and presence section.
The Divalo ran on a 12AX7 and 6L6 tube complement. Its control layout comprised Master Volume, three individual Volume controls, three individual Gain controls, Bass, Middle, Treble, Presence, and a Boost function. The rear panel provided three speaker output jacks, an XLR speaker emulator output, and a Class A discrete instrument-level effects loop with dedicated Send and Return jacks. A standard guitar input and a footswitch jack completed the input complement. Channel switching and Boost activation were handled via the RF4CHB four-button footswitch. The unit measured 27.00 × 9.45 × 10.04 inches and weighed 44.09 lbs.
Owners sourcing replacement tubes, speaker cables, or footswitch accessories should verify compatibility against those specifications; a qualified amplifier technician is best placed to assist with biasing, servicing, or any internal work.
STRAIGHT TALK
What Stands Out
Keep In Mind
From the people who own them
Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.
Owner photos
Put yours on the record.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
What do you know about this one?
Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
