Happy trails.
that looks very doable, how much would the supplies cost to build this be (approximately, chasis not included, but psu included)? of course i would want to build 2. no need for a preamp with stated sensitivities.

i have access to bench dc power supplies, oscilliscopes, you name it. but they are not at my home.

Hi Miasma,

Just looking at some prices:
Example of Aleph 3.
Aleph boards (via Harvardian?) $45
Harvardian free Q pack of zeners and smaller transistors
BOSOZ board-stereo (via Old Colony) $20
4*26000uF 75V Caps (ApexJr) for Aleph PSU $28
Output mosfets $15-20
Transformers (Don't know US prices) $?40-50
Caps for BOSOZ $???

No need to populate the boards with the most expensive resistors, etc at this point. If you like the sound, you could upgrade parts later on. Heatsinks from ebay or ApexJr perhaps?
Might push the budget, might not. Having access to all the equipment mentioned will save loads on chassis.

I'll admit I am biased as I've just started ordering parts for an Aleph 5. Whichever route you decide I hope you'll enjoy the journey and the destination (Oops, I'm waxing a little metaphorical).

Have fun,

Paul

$10 for resistors
$25 for capacitors
$50 for a xfmr
$30 for transistors
$5 for a bridge
$18 for a psb
heatsinks ???? I lean towards salvage $20 ???? your call
maybe $40 for wire, solder, diodes, beer, fuses, switches

totals about $200 plus 25% just cause chaos rules
and your looking at $250 easy as key lime pie.
Do you like key lime pie?
I like key lime pie.
A girlie girl is in my kitchen as I type
making key lime pie.
Life is good.

so i should expect about $250 for each channel?

so, around $500-$600 for the entire built amp with PSU?

is there a better deal than this anywhere?

You won't find a DIY amp in your price range that is cheaper than a commercial unit. Don't do this to save money. Especially if your time is worth anything.
"wire, solder, diodes, beer, fuses, switches" all add up. Beer? Sounds like a great idea.

time is of little importance here. i want the satisfaction that i built my own amp. it seems i simply cant afford an aleph, knowing that, are there any other designs in the same price range ($700) as the design that i mentioned i lied, that will work any better?

Another well-reviewed amplifier is the 55w AKSA from www.aksaonline.com.

AKSA review: TNT-audio.com

AKSA forum: Harmonic Discord

Cost with power supply should run around $300 USD or so - it's next on my build list.

HTH,
Nikhil
