75 amp power supply

What ya git? I still ain't got mine out the box due to lack of adequate pwr supply. Been eyeing the powermax pm3 lk or the pm4.
How does $15/piece sound? From Missouri. Or am I just speaking to the wall and a $180 unit that does not even come close to a $1000 (retail new from DELL/HP) server power supply in terms of circuitry and durability is the talk of the town?

Yes, that's 3100 degrees F. Nine yrs of hard work.
Hello Undertaker,
For my N2 I run the Pyramid 36 and according to the meter on it, it draws 21 -24 amps and that's at full power of 225 watts on SSB.
Everything works just fine with the PS. If I remember correctly it does around 250 on AM.
I have had excellent luck with the Pyramid brand, only one failure of one that was used for 8 yrs.
Your N2 should work ok on 35-36 amp supply if the radio is tuned good. I have heard several people in the last several years on DX say that they were running a 35 - 36 PS with their N2.
Here is some food for thought:
When I first got my N2, I hooked it up to my Pyramid 50 amp and keyed the mic on ssb - WOW!! The watt meter hit 300 and the radio shut down and the PS almost went dead. Damn, I thought I had killed my new radio...
Anyway to make the story short, the radio was still working ok, but I then sent it to DTB radio back to PA. I told Dave that I wanted a complete tune and bring full power down to 225 watts on SSB, also told him I wanted it to work on the PS 36.
Well when it came back here are the numbers:
SSB - 225 watts
Amp draw is 21-24
I have had "0" problems with this radio so far.
(I run the N2 at 14.1 volts - that's what Dave tuned it at).

Na....I'll pass. Don't wish to convert them so they will work.....thanks for the offer.How does $15/piece sound? From Missouri.

I am not offering anything except information for those interested. If you don't want to convert "you gotta pay the price". For those willing, considerable cost savings and benefits await!
I'm not that skilled, I could try, find the info, parts, and try. But being a full time RV'er the PM3 100 amp will be a great backup power converter for my camper. The current one has miles on it, been replaced once before. Nobody, stocks it. Order and wait. There is info on Powermax site how to replace my exact unit with a Boondocker converter ( same PM converter, different name).
Contacted Powermax today. PM3 will run equipment with or w/o battery connected.
Currently have a 55 amp unit, PM3 100 amp will be upgrade should current 555 fail.....again!
Maybe I should get a couple of the HP's for backup for my backup to run radios should current PS fail.
How difficult is it to convert?
Very easy.. Just solder two points together with a small piece of wire... Thats it.... Solid 12v
Hmmm.....dave457....you now have wheels turning in overdrive.
