Group order for Non-inverted LM3875 Amplifier kit - Phase II
I am now taking orders for all kits:
https://www.BrianGT.com/order
No need to fill out the below Wiki
Introduction
Well, the initial group order is going well, and I am looking to start offering kits again in April, after I get all the existing orders shipped out, and take care of my wedding at the end of this March.
I am thinking of offering 2 different kits, a Basic Kit for $35 and a Premium Kit for $65. The premium kit will be the same as the one from the initial order, with the addition of a pair of Blackgate 4.7uF N capacitors for the power supply. The basic kit will standard components, which most closely match the premium components, but for a fraction of the cost.
The LM3875TF will be in all kits, unless you request the LM3875T in the comments field. From the first order, 90% of the orders were for the LM3875TF, and it is much easier to work with.
I am generating a list for the interest for the kits to see if it is worth the effort of creating more kits. The list is for declaring interest only at this time. Near the end of March, I will put together a new ordering page.
If you have any questions, please post them in the thread, and I will attempt to answer them for you:
