Lovoltech LU1014 Power Jfet Group Buy

[wg45]

As you can see I am shipping items. I'm working through the list from the top down. If you're near the bottom of the list, hold tight, I'll get there.

Right now, most of the shipping is USA based, since I can use a flat fee for postage and paperwork is minimal.

I've sent out some test orders for the rest of the world to get an idea of costs. Once I have a better idea of what's involved, I'll start shipping more overseas orders. It will go slower mostly due to paperwork.

The good news is that we should have enough items to fill the demand and have some leftover for latecomers. Please be patient.

I volunteered for the GB thinking I was going to be distributing a few of Papa's LU1014D. That snowballed into 500 LU1014Ds, 1400 PCBs + Resistors and a couple hundred header pins. I think there's going to be a lot of LU1014D influenced amplifiers being built very soon.

To borrow a phrase- I blame Pa!

 

[Francois G]

We will blame Pa, and thank you both profusely. This must be a big job and labor of love. We appreciate it very much.

 

[Vunce]

Indeed, A monster of a GB this snowballed into!
Thanks wg45 and all others involved for your massive efforts here, Bravo!

 

[Neat Ripple]

Thank you for your hard work. Much appreciated.

So how do I change the amount from what the Paypal request is? I've attempted to click on everything that shows the dollar amount, and nothing will change. Do I have to pay the requested amount as goods and services separately, and then send the extra separately as a gift?

Scratching my head here.

Ended up ignoring the invoice/request and initiating a new payment. Non-intuitive.

 

[pfdavid]

That's exactly what I did. Seemed to work.

 

[chromenuts]

Same situation with my Paypal invoice. I didn’t know what to do. Decided to send it as “someone I know”. I hope that means no fees? I included my shipping info in the note.

 

[wg45]

Paying F&F there is no deduction by Paypal. Goods and services, there is a 7-9% withholding. Go with what you are comfortable with. Either way is fine with me. I figured it would be about 50-50.

Please, no extra money. I'm just doing this to help out the community.

 

[nautibuoy]

Thank you wg45.

Please, no extra money.

In that case can I suggest that a charity donation would seem to be appropriate, perhaps to the charities papa nominated as beneficiaries of the VFET lottery?

Donations to two great charities – diyAudio Store

 

[chromenuts]

Also...if you make a donation to DIYAudio you get perks as a paying member ...and that supports this community which has great guys like Will who volunteer to do stuff like this...thanks!...just another option.

Just throwing out there another really simple yet super sounding SE Class A headphone amp or fleawatt speaker amplifier with 12v supply is also possible with LU1014D using the LuFo Lite amp.

LuFo Amp - 39w SE Class A from 28v Rail

You can listen to a video of it here on my little 3in test speaker:

Or if choke loading is not your thing, resistor loading works too but strictly a headphone amp:

In case it's of interest to anyone, JLCPCB have just introduced aluminium PCBs as a service and are offering 5 boards for $2 (or 10 fo $5) - plus shipping of course.

PCB Order & Online PCB Quote & SMT Assembly Quote - JLCPCB

 

[xrk971]

Yes, I saw that too - great prices from JLCPCB. This opens up making aluminum front/rear chassis panels with perfect cutout holes and labels. 🙂

Except that they want to make aluminum in white solder mask.

@wg45. The GB spreadsheet seems to be locked. Am i too late? Ideally I’d like 2 kits plus the LU1014s, but if not would take whatever is available - ?

 

[vitorio]

@wg45: I would like 2 full kits + 3 pcb pairs + LU1014 pair, if posible.

I've also sent a message through google asking permission for editing the Group Buy signup sheet.
Thank you for your time, also to Papa, woofertester, XRK and all the nice people who help to run this Group Buy

No worries. I can add you to the list for-

1 pair of LU1014D- NC
3 pair of PCB+resistors $3

I'm afraid we might be sold out of the header pins that make up the PCB kit.

Please send me a PM with your email and shipping address.

 

[jwjarch]

Received my package wg45. Thanks again for all the hard work putting this GB together!

 

[xrk971]

Yes , a big thanks to Wg45 and Woofertester. I am using the matched JFETs that Woofertester sent me for the LuFo Lite. Check out how close the bias currents between the two matched channels is? This amp has no adjustments so whatever it ends up on is it. This is voltage across a 1.50ohm 2% resistor. That’s within 0.15% match on the bias currents!

 

[joaoranito]

Hi, I'm from Portugal and it would love to have access to 1 pair of LU1014D and 2 pairs of full kits. Is it still possible? Would you ship to Portugal?

Thanks in advance!

Hey Will -

The eagle has landed! Thanks to you for all of the effort, and thanks to Nelson for another generous gift. - Pat
