[NLRS] Fw: Help 50 VDC at 60, or more amps

[scsueepe at mtcnet.net]

Yes the blade PS, used to be able to get them for $25 until everyone found about their use... Still at 57A doesn't quite get there in my experience with my Larcan for 1200+ watts.  I did use the HP version (same specs) of these blades to power my W6PQL 1 KW amps for 222 and 432, they worked great for that.  

There is a bit on the internet about paralleling these, but I never looked much further than to see that a few did it.

This one,

https://www.ebay.com/itm/167557943193

was suggested here,

https://mmra.org/larcan/

(18) available at $250/ea but kinda spendy shipping at $73. I bet that's because they're heavy...
