Default Simple SE build costs

Does anyone have a simple break down of costs of a simple SE? Ive seen quotes for $400-500 and others lower.

Ive build several amb headphone amps in terms of experience. This will be my first full tube amp (well other then regs and rec).

Parts i have:
case
connectors
equipment

I need a parts breakdown of the rest so i can see if this project is within budget or if i find a deal i can spend more on tubes or other areas.

Go to mouser and use this list to figure out the costs for the components to fill the board. At the bottom of that page you will see the part numbers for either mouser or digikey. You can find the component cost from there. Some of the items that say not stocked at mouser I have found.
Parts Lists
IXCP10M45S
120UF Capacitor
So you should be able to get most of your board items from mouser.com. You can find socket and coupling capacitors at tubesandmore.com, tubedepot.com there are many other sites out there.

Transformers is where you can spend a great deal of money. I have the big edcors along with their power transformer. I have around 200 invested in the three transformers. You can purchase some of the smaller edcor transformers and shave some money off your overall cost. $10 for a motor run capacitor. $35 for the board. Then you have to pick out tubes. Again that can be expensive or it can be cheap. It really depends on your choices. One thing you may want to factor in is shipping. Allied has a cheaper transformer that will work with this amp but when you factor in shipping it may be cheaper to purchase all of your transformers in one place.
I think I spent around 500 on my simple se.

Your biggest expense will be transformers. Shipping adds up too, so if you can keep your suppliers to a minimum you'll save. I'd guess if you can find all your parts from Edcor and Allied Electronics you'd save the most in my opinion. You may have to fudge some parts though.

Agreed...unless you want to stuff the board with boutique parts, the cost for that part is fairly fixed. The wild cards that jack-up the overall cost are:

1) Output transformers - Anywhere from $14 to $400+ each. Lots of people use middle-of-the-road Hammond or Edcor here, the latter seeming to be of slightly better quality for the price. There is also Transcendar on eBay if you can find them.

2) Tubes - uses fairly common types, so you can go Chinese and spend $50 or so or go NOS and spend $100's just for one tube.

3) Coupling caps - even George recommends a better cap here. You can get Orange Drops for about $5 for the pair or spend $100+ each for PIO silver caps. Audience Auricaps are a popular choice here for something a little nicer but not completely crazy.

I spent:
Allied PT $55
Transendar OPT $112
Hammond case $50
Motor run caps, choke, misc parts and board (the board is so cheap I can't remember what I paid!) $125

Call it $450 with a pair of EH 6CA7s, TFK 12AT7 I had on hand and Sovtek 5Y3.

Allied part 862-6224 for a 120uf 500v cap, 862-6200 for a 33uf 500v, that should cover the hard-to-find capacitors. Everything else should be easy.

I got a pair of Edcor GXSE transformers shipped for about $50.

$100 for transformers, $43 for the PCB, $50 or so for components. I'd say you might be able to do it around $200 without tubes.

TUBELAB 55$ (board+ transp)
TUBEAMPDOCTOR 146$ (Tubes, caps, some components)
URALTONE 76$ (choke, some components)

I built mine for $300 but that was a while back, prices have gone up, so that is probably closer to $400 now. I have heard from builders in the US who have spent about $1000, but some of that was for some rather fancy and beautiful wood work.

Most of stuff came from US, cost for transportation is around 25-30%, so you are close to the truth. Of course- as I build it to replace my Sony, I did not build it on low budget bases.
