Hi Ray, I'll chime in on this one. My Magnum MS4024 is fine for old tube amps and the recording equipment in my studio -- very low noise floor -- but I have to power guitar pedals with 9v batteries. Powering the pedals with wall warts causes a huge 60Hz buzz. I've tried different transform

The load was 8 Marshall Super Leads for my application. And while EVH used a variac for test and studio in early days, he toured with Super Leads and then to the EVH amps with 4 6L6 vacuum tubes each. A few others also. I saw his backstage set-up in the 80's and he had an AC supply regulator with a

Hi Ray, Given how small your load is and with what Bryan has suggested, it would be a very inexpensive way to go. If you need battery charging while using it and you find noise through battery charger then using a 2 battery system with harness of Anderson connectors would all you to disconnec

Ray, we use Samlex on our oyster farm.  We have a 24 Volt system which powers pumps and an oyster sorter. The sorter takes 240 and transforms to 208.  We have not had any issues except that we sometimes have to turn off the inverter and then back on to energize.  The GFI is also a little cranky

Not to jump on the Outback bandwagon But while I was there many, many stages were outfitted with Outback inverters... The only thing I'd watch out for is when charging, if you have to charge while the band is playing, you might get some 60hz noise... Just depends on how clean the install is,

Hi Jay; Another great question, that I can't answer.  The continuous watts would probably meter at 100 watts or so, but the transient peaks can be quite a bit more. How much more, depends on how fast your meter capture is, but the ear can hear up to 20 kHz, and my meter can't catch transients

I second the Outback power quality. We built a mobile medical lab that has Xray, ultrasound and other sensitive lab electronics. A 120kWh Li-ion battery package with 8 Outback 3.6kW stacked inverters @ 48 volts has been operating almost weekly for over 3 years. Run from Samlex. We were burned S

Wrenches I have built solar powered sound stages, power trailers for both music and drive in movies, l only use outback, never any complaints, some acts prefer over dirty grid power. I had sunpower positive grounded arrays, AC-DC Coupled arrays. I had a guy use SMA and had all kinds of issues, main

Hi All; I've just had an inquiry on building a portable sound stage and recording setup.  Traditionally we've always used Exeltech, as they've had the cleanest output, with background buzz on tube amps being lower than grid power.  Modsine were horrible, Old Trace SWs were pretty intolerable,
