Group order for Non-inverted LM3875 Amplifier kit
Introduction
Well, this order has gotten significant interest so far. I have decided that I will be offering 2 different kits, one for the including the LM3875T (Non-insulated version) and the other containing the LM3875TF (Insulated version). The cost of both kits will be the same. Read the below for details about the kit contents
If you have any questions, please post them in the thread, and I will attempt to answer them for you:

Kit contents:
| 2 | Non-Inverted Gainclone pcbs |
| 1 | Power supply pcb |
| 2 | LM3875 (T or TF) |
| 4 | 20 kohm Caddock MK132 resistors |
| 2 | 220 ohm Caddock MK132 resistors |
| 2 | 620 ohm Riken 0.5W resistors |
| 4 | 1000uF 50v Panasonic FC Capacitors |
| 8 | MUR860 On Semiconductor Diodes |
| 2 | 4.7uF Panasonic FC Capacitors |
| 2 | Aluminum oxide insulators for T version |
As far as the 2 different kits, the insulated TF version will be a lot easier to work with, mounting to the chassis, but the thermal transfer properties for the package aren't as good. I will be providing insulators with the T kit.
I will not be offering any other configurations other then the 2 kits, and the bare pcbs at this time.
EDIT: I am now also offering LM3875 chips for $4 each.
Pricing
Kit (with contents above): $55
Set of bare pcbs (2 channels and power supply pcb): $15
LM3875T or LM3875TF: $4 each
