Mono Amp Powers Supply's

[WOPL Sniffer]

I thought they should be just from the amp draw perspective....

Current draw will be the same either way and in my case, the size and weight is the problem.

I GOT IT...... 2 antique bird cages for chassis'

HUH????

Builders block eh??

I have 2 separate 120 feeds going to the rack so we're cool there...

 

[laatsch55]

Mine will be 2 per channel also...the idea was to be able to double down into 4....without running out of power supply...

Indeed. I need to get an electrician in here. I had a guy I built a couple amps for and he designed his house around his stereo room. He has several 20 amp circuits coming in to the room so running all that equipment is not an issue. I may call my electrician soon. That has always been an issue her in my house. Plus, My house is out here in the county and is ALL electric.

Builders block... You got that right bro

Yup. Thats the ticket. I think you have the same toroids that I got from that dude.....

 

[laatsch55]

Yep, sure do...


It'd be nice to build a house around "the room"....

I'm a retired sailor and the price of this is crazy. I haven't even bought the 44 outputs (2 drivers and 20 outputs per side) yet.

 

[laatsch55]

Amen , it gets pricey in a hurry...

Don't know how much heat these transformers will emit when cranking the tunes, but they could be stacked and built into a relatively small aluminum box with fans. Leaving enough room for EMI shielding, soft starts, and caps....

Been collecting parts for quite some time as have you.

Gotta start measuring footprints for the power supplies. If I don't separate the components, you'd never be able to lift the shit.

I remember something about stacking toroids, and noise and vibrations. Leave enough lead length to rotate the toroid if need be. I'm gonna have a toroid on each side of the caps , that's a fairly large enclosure. It will also be covered in perforated stainless steel plate. Small holes , like about 1/8 inch...Good for heat dissipation..

Key point right there!!

 

[WOPL Sniffer]

If they act like inductors, they should be at 90 degrees to each other. EMI shielding with some separation for sure.

 

[laatsch55]

That's pretty much what transformers do....induct.....A LOT!!

 

[WOPL Sniffer]

Si.....

 

[WOPL Sniffer]

Well, I think I found a suitable enclosure. It's a snug fit, but there IS room for a fan for pulling heat out. It's sturdy, and Government issue...... And, OD GREEN (For now).

Doing a test fit.

Not your basic 5.56 ammo can.....

 

[WOPL Sniffer]

I need to fit the fuse holder, a power connector and an On/Off switch (and a Fan and feet of course), and then it's time to test the first channel......

I like the repurposed ammo can Perry...

 

[WOPL Sniffer]

If Beefy Bob can do a Coffee Can, I can do an ammo can right????
