I actually bought a few boards from you a few years ago. Highly recommended . What happened with Tech-DIY.com?
It complicates my entire tax situation -- and takes a lot of work. I have actually taken folks boards back and re-soldered them to get them to work!
US Postal Service has made it very difficult to compete worldwide. I got a shipment from Germany 600 gram by weight cost the fella 2 euro to ship. I went to ship a package of equal weight to a fella in Belgium today and it was 23 USD . Same with goods from China -- and there's some really excellent stuff coming out of the PRC!
My philosophy was to sell the boards near cost as the intellectual property was not my own, but I got to keep a set for myself at zero cost. I did the same with SY's "Impasse", and "His Majesty's Noise" and Dr. Marsh's quite excellent (really) headphone amplifier.
Take a look at the TI datasheet -- I offer no apologies for implementing their basic design. At $3 a pop, I am not investing any energy in walking someone through a text-book/application note design vetted by a multi-billion dollar company.
I really like the datasheet application notes, so that's perfect.
I need to wait a bit but I'll probably reach out to grab some from you soon.
I have parallel, bridged and dual boards -- $3 each as the LM4780 is discontinued.
Hi,
I sent you a private message about these boards few days ago...could you take a look please.
