$175 Class D amp--120 wpc

Works for me! It's the sound that counts. Maybe you could put the LED's in the handle holes??

I'm currently building a box for my new 250 using my friend Mark's as a prototype. I have to say, it's a real challenge matching his accuracy.

No closeup shots of this one. Uh uh.

This is with the volume at 80dB and listening to rock.

This is the Amp draw from the Class D amp.

Watts=10w (my 300wpc Class A amps idle at 600w)

Jason, did you happen to check the idle draw of the Class D? The reason I ask is that I have been only turning mine off with the side switch, not killing power. I would check myself but I dont have a way to do it at the moment.

Thanks,
Ed

Before I leap, I'd like to look at a list of what I need to add to the amp kit to make it functional. I've seen mentioned an IEC connector, RCA connectors, connecting wire for ??? Does anyone have a list of what's needed to make this amp functional?

I'm a total amateur, so am likely to get lost without it. I take directions well, generally, but I need to know what I need.

Price check now all I need is the guts
1. Old NAD tuner 8.00
2. New back panel 3.00
3. Poplar and handles 8.50
4. quart Minwax Clear 16.00 to use about 3 taplespoons worth

I'll be doing one soon enough. However, I'm going the moderately expensive route. Unless it turns out to be butt ugly

, I'm going to get one of jtwrace's custom cases.

Going to do the 1000 watt kit and use it in 4 channel "mode." Have already dropped over $100 on the 4 RCAs, 4 sets of binding posts, Furutech IEC (all previously listed parts I got from Cryoparts) and wiring.

Don't even have the amp kit yet!

Spending a little more on "upgrades" now will prevent me from having the "what if?" upgraditis that I am prone to. Guess you can call me an audiofool.

Paul, we have the same symptoms of this disease! So, the binding posts, IEC and wiring is all you need to make this guy go?

Beautiful job!! This has to be the quickest case assembly yet. You win the prize for fastest!

As for a parts list, if you're going to put it in a case the minimum you need are:
2 RCA connectors
2 pairs of binding posts
IEC (you can buy one with an integral switch and fuse to eliminate those extra parts.
Connecting wire for your power supply 16 ga.
Wire for connecting the RCA's to the board--could be 22-26 gauge.

No. You need the amp kit itself, too.

(just kidding, of course!)

Yep, as Steve listed, that's all you need. The RCAs are optional, if you don't want to use the ones attached to the amp module. I will be getting my kit w/o the RCAs on the amp modules. You can also directly wire up the tranny instead of going the IEC route.

Hehe.

As I said in a PM the other day, after looking at your DIY sub, I know I am going to enjoy the case!

Funny comment - while wondering about possible shortcuts in building a case, I am considering just using a kitchen drawer and putting a piece of perforated metal on top. Why not?

You'd probably need a sturdier bottom to hold the weight of the transformer. Also, getting the connectors through a thickness of material might require some work to mill it out on the inside.

At idle the amp draws (125VAC):

.9 watts
.11 amps

This is with the amp on just no music playing.

I did a little progress on my box but still need to drop-in the guts.
Maybe this weekend
