SOLD
ASKING $225 including Continental USA shipping
This is another project I will not build, seeing if another might have an interest in it.
Designed by Jason Leaman and others, this is a super heavy duty implementation of the F5 with a stout CRC or CLC power supply board.
He used some atypical parts, mainly the SOT 227 footprint power mosfets and diode bridges. The boards are NOT UMS mount compatible so you must be provicient at drill and tap of heatsinks.
The signal boards call for mostly MELF resistors, but use standard 3W power resistors. ixys IXTN40P50P and IXFN140N30P huge mosfets are used and mount the boards to the heatsink. Screw connectors can board mount for wire attachment.
dimensions: 260 x 52 x 1.6mm
I include all parts needed for the signal boards except the input jfet J74/k170 pairs, the spade connectors for signal input and signal ground, if you want to use them, and SMD LEDs. The mosfets retail for about $75 per board.
There is a schematic and BOM included, support from Jason has been hard to come by, so I suggest you are an advanced builder, familiar with First Watt amps and power supplies if you take on this project.
The PS board is HUGE (244 x 189 x 1.6mm, NOT UMS mount compatible) and can be set up for CRC or CLC filtering. I will include the Microchip APT40DR160HJ Diode bridges that fit the boards, 16/ea Nichicon 15,000uf 35v capacitors, screw mount connectors, and fuse holders. No resistors, film caps or chokes included. There is no schematic or BOM for the power board. Pretty self explanatory, and he runs over it nicely in the linked video.
So, for less than the cost of the 6 SOT227 parts and the 16 PS capacitors you have a partial kit for an F5 type DIY amp. You supply the other board parts, chassis and chassis components.
