Would be this amp (the arcwelder) suitable to power a peerless 830500 subwoofer? Anybody use it in that way? Or maybe advice for another amp.
Overkill , Just 3 pair outputs and a lower (45-0-45 Vac) trafo for 60 volt
rails would push the peerless to it's limits.
You could even drop the input stage voltage in the cap multipliers to
limit the acrwelder output to a safe level.
All 5 pairs (with 5 pair MT-200 sanken outputs) would most likely push the 500W
subs all the way.
For instance , Dayton Audio UM12-22 12" Ultimax DVC Subwoofer 2 ohms Per Coil
This sub ... wire the 2R DVC in series , 70V rails , 5 pair of the big sankens.
Scary....
PS - for the peerless I would use the arcwelder ... for 500W subs - I would go Class D. Class D could go inside
the sub enclosure , just the plate of the amp could be the heatsink. A 250W arcwelder would have a managable
external heatsink 250mm x 100mm.

Which version of the slewmaster is better distortion wise the EF3 or the Arc Welder edition? What is the difference?
All are EF3.
The smaller 2/3 pair versions would most likely have more distortion with
2/4R loads because of current limitations.
The "arc welder" had massive 20A traces/5 pair , hence the name. At >10A+,
just the layout could increase/decrease THD.
Otherwise , all versions are identical.
If you want go all the way , Arcwelder + 5 pair Sanken MT-200 230W BJT +
1000VA 60-0-60 trafo + 100K uf caps - drives the biggest subs out there !!

Van I use 7 pairs? I have a big 5U case from modushop and I want to make more use of those big heatsinks. I already have NJW0281 and 0302
Thimios,
Hello my friend. For this amp I used two arc welder boards per channel. I cut one off to add two more pair of outputs to the standard five pair board.
Harry,
Yes, the two heat sinks make a tunnel with the fan in the back and the vent in the front.
