[RE-wrenches] Sound Equipment Inverter

[Bryan Norkunas]

I have built one small music studio with a Samlex pst-1500-24V and it turned out wonderful -  though this was not the inverter w/the built in charger.  

For the next studio build, it will be my personal studio and I am considering the SAMLEX, EVO-1212F-HW.   This build will be finished late next month and I will let you know how it works out.

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, Magnum's were usable, but still noticeably more buzz than 
grid.  I think THD is roughly associated with the background buzz, but 
there might be certain harmonics that are particularly problematic.  I 
haven't gotten into looking at the separate harmonics relative to what 
induces the most noise in these old vacuum tube circuits.

This is a 48 v application that also needs a built in charger with 
transfer switching.  Exeltech does not appear to have anything in that 
department.  Any other choices?  How are Samlex?

As always, thanks in advance for your time and expertise,
