The Hiwatt DR103 Custom 100 is a classic amplifier known for its robust build and iconic sound, favored by legends like Pete Townshend.

Beautiful, Powerfully Clean Sound!

My Hiwatt DR103 Custom 100 is an original 1974 with the Linked Input modification done by Pete Cornish himself. I'm in line for another 1974 DR103 without the mod. All Hiwatts have Mullard late-70's (new badge) matched tubes installed.

Late '70's early '80's version. Re-capped and re-tubed. Sounds great!

Used as David's main amp from 1969 until 1987 and then reunited in 1994 and is still in use. According to Gilmourish, "During the Division Bell tour in 1994, David’s rig consisted of overwhelming six Hiwatt heads in two separate racks, – not mentioning all the spares he travelled with." Afterwords, he returned to using three heads.

"David is using a pair (and one extra) Hiwatt DR 103 amp heads. They are his original 1974 Hiwatts, with OLD tubes (well used but still work fine, as tested by Pete Cornish). He is running them through WEM 4x12" cabinets with Fane Crescendo speakers in one and the other has celestion 75s (clean speakers which don't sound so good alone but along with the Fanes he gets an awesome tone)." - Analogman website.
