    Are they thin sounded comparing to more traditional(and heavyweight) 2U power amps?Thanks guys! :bassist:
  2. The single rack unit Fender power amp I've got sounds fine. This is a traditional linear power supply model, though, not a switching power supply, so it weighs a freakin' ton and it extends very deep into the rack.
  3. I use a Soundtech PS802, and I think it has plenty of "beef"
    in the sound.

    Peavey and Stewart both offer 1U power amps.

    My only problem with them is most don't provide fan cooling so even if you have a 1U power amp and 1U Pre amp you still have to have an extra space in the rack to allow for cooling. Otherwise over heating can be a big issue.

    Actually, if you are willing to pay, the Peavey DOES have a fan and lots of power.
  7. The PS802 has dual cooling fans.

    I have a Peavey DPC 1400x,and couldn't live without it. 1 rack space,about 14lbs,and it has a cooling fan.My entire rack weighs less that my old power amp by itself.They are a bit pricey,but there are usually a few floating around.I got mine from a fellow TB'er for 700.00 in mint condition.

    Can be an issue but is not automatically an issue. I use a Stew 1.2 in a 4 space rack with no space above it and have played outdoor gigs for 4 hours with no issues whatsoever. As long as you have it so that air can reach the back and the heatsinks, it's not necessary to have an empty space above it although it certainly won't hurt.

    I have a single space older model Carver - the PM300. It's 300 watts into 8 ohms bridged and I run it with an Epifani 110UL for "unplugged" coffee house gigs. The Carver has terrific tone and a very detailed sound. The other night at a full band rehearsal I used this rig, and then switched to my WT400 which is roughly the same power output into the 8 ohm Epi. The Eden sounds way less HiFi than the Carver but the depth and punch of the WT400 was a big step up. Some of that can certainly be from the difference in preamps (using an Ag 659 with the Carver), but I tend to think it's mostly that the Carver, as an example of an early switching power supply amp, is a bit lacking in beef.

    Didn't even know Fender made a 1U power amp.
