Yesterday you told me that you had less then 10 shipments left. What is the status today?

Scribble · 28th May 2009, 10:40 AM

Do you require my details or anything in order to send me my 10 boards?

tryonziess · 28th May 2009, 04:51 PM

To all,

Guess what I got today. A nice thick stack of BPA pcb's. I will be distributing them out to the U.S. members starting this evening. I am hoping to get the boards in a standard envelope with cardboard backing and ship as regular correspondence. Should be about 75 cents per pair, which I will pay.

Rhysh, could you email me the paypal list you have and I will know who to send them to and who has paid. Thanks for your efforts. Anyone who has not done a Group Buy needs to experience it just once. It can be a real headache.
Anyway everyone should have there boards by first of next week.

Now who is going to step up and run a group buy on Lundahl transformers. They should be a perfect addition to this design. A truly balanced input source. Any takers. Alexw88 has the transformer model on his website. Shine7.com. I beleive Rhysh might be able to provide the model. Of course the op amp method works just fine.

Tad

I belive you will need to drive the transformer with a gain stage. A lot of people may have fully balanced systems allready, like myself?

rhysh · 28th May 2009, 05:29 PM

I will get that paypal list to you shortly, some family are visiting at the moment.

rhysh · 28th May 2009, 05:36 PM

The transformer model is Lundahl 1545a. If someone organises a group buy, im happy to design some PCB's and send them to the group buy organizer, unless people are willing to use stripboard

.

Thats a long way off anyway, this needs sorting out first.

rhysh · 28th May 2009, 05:42 PM

Just a big thankyou to tryonziess for helping out with this.

HaLo6 · 28th May 2009, 08:14 PM

How much are the Lundahl trafo's... I am interested!

rhysh · 28th May 2009, 08:15 PM

Im not sure, but someone needs to volunteer to run the group buy first. I quite fancy a transformer myself.

HaLo6 · 28th May 2009, 08:52 PM

I may volunteer... standby... what is the part number we need and I'll start the correspondance with them.
