Leach clone, pretty good looking

is that data for the 4 transister board or the 10 it looks a little small for the 10 ..

That is the 4 transistor version.

Re: Boards arrived wohoo!

Finally the boards arrived today

An externally hosted image should be here but it was not working when we last tested it.

hi jens,
can you advise me thru email how i can get hold of a pair or two of these boards: tonyjtec@yahoo.com, thanks...

I would also like to obtain a pair of these... I can't seem to find anything on the Delta Audio website about your selling them, but perhaps I'm just being obtuse?

Well I'm confident that the board works, so anyone that want boards should email me. The webpage has not been updated yet.

Price is 250 dkkr convert that into US$ and that will be the price.
Please add about 30 dkkr for skipping.

The board is 2.4 mm thick and has 3 oz CU.

The parts list is not finished yet, I will be working on that this weekend.

Quote Done

Ok people i have the quote for the smaller version for 4 transistor Board. i'm going to start a new thread on this after permission from Jen's and other info Maybe i should go a canadian version of the 10 Transistor model ? Jens please email me or message me ..

There are plenty of those around where you live.
You dont need more !

Boards for sale

Hello all,

I have some extra boards from my own order. To get some money for heat sinks I have decided to sell one PCB + four 10.000µF 63V ELNA caps where two of these fit on the board.

The caps are leftovers from work, so I will charge nothing for them. The caps are not for sale separately, because I got a really got deal when I got them.

The price is fixed at US$ 45 + shipping for a set of caps + PCB.

Interested builders should post here; I have 10 boards for sale so whoever posts first will get boards.

\Jens

 

[jacco vermeulen]

2 boards please, Jens.
Where is the cashiers office ?

A suggestion where to get the MJL4281/4302 overhere i welcome.

 

[EFHeath]

Just to confirm that I would like two boards. I have sent you e-mail as well.

 

[JensRasmussen]

Hello Jacco and EFHeath

Orders noted.... 6 boards to go.

I order output transistors at the local shop www.el-supply.dk

I'm putting together a list for them so I can get a price for a complete set of components from them, incl silicone insulators.

Please email me you address so I know where to send the boards.

The price US$ 45 is for ONE (1) board and four (4) caps. Please add shipping costs that I mail you......

\Jens

 

[Villaw]

I want two as well Jens
Thanks

Test results for today:

Rails not loaded = 63V
Rails loaded by 8 Ohm = 56V

Peak output 50V @ 1 kHz into 8 ohm = 156W

This was done using a 800VA transformer (The black thing in the background) The Dummyload is restive

Test signal

20V/div

a 800VA transformer (The black thing in the background)

Ah, thats what it is !

2 *40 Vac ?

 

[JensRasmussen]

Hello,

Close.... 2 x 45 AC = +-63V

Measurements into 4 ohm

Hello,

I just measured the power output into 4 ohm.

Vpeak @ 1 kHz is 47V with no clipping this is about 275W RMS into 4 ohm.

This fits very well with the 150W RMS into 8 ohm I measured yesterday.

More info here

Hello,

All left over boards have now found new homes.

Thank you to those who support me by buying the extra boards
