This 1979 HiWatt DR504 was actually a lot of fun. There were some halfway thought out mods done to the preamp to try to get it back to earlier 70s specs, but the real party was in the main power filter caps. The originals had been left in and some sketchy, undersized caps that had been salvaged from some piece of mystery gear had been soldered in as replacements. The whole mess was held in with a big pile of hot glue. I exorcised all of the evil caps and replaced them with brand new JJs. The sound from these is as unique as the hype says it is. Big open chords soar and jangle in a way that make you want to windmill your Les Paul until your fingers bleed. Go check out the Riffbrokers to see this glorious beast in it's natural rock and roll habitat.
