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.](http://www.analogman.com/graphics/gilmour/david.htm)more
"Amp-wise, Eddie is using a vintage 4x10 Fender Super Reverb, but he may switch to a '72 100 watt Hiwatt. Eddie definitely has a Who/Pete Townshend fascination, hence the Telecaster/Hiwatt combination." Guitar World 4/95 A Guided Tour of PJ's Gear by Tom Beaujour "Pete Townsend always used to use Hiwatt amps. See what I mean? Sentiment. The Hiwatt is an early 1970's "DR 504 Custom 50" 50w head. He also has a "DR 103 Custom 100" 100w." From “Pearl Jam Sinergy” (updated to 2002)more
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.
