Nor will I.
I will probably only populate with two pairs of outputs. The second set of boards will be as spares if I decide to go bigger later.
Glad the mono/stereo debate is over. To each there own, I may mount the heat sinks on the outside wall outside and spray water on them when I want to listen to music. I have a garden right under that so I can grow strawberries in the winter and corn in the summer.

Toecutter, could you list the options and features you are considering? MAybe we can have a vote. With enough volume it may spin off in several different versions of boards?

UKToecutter · 22nd February 2012, 02:01 AM

I've relaid the original board as an F5 V2, so two N & two P Channel Mosfets on the board.

It seems the general consensus is that the V3 needs to have split N & P channel boards for each channel.

Also, The V3 requires one power supply per channel and the V2 can work fine on a single power supply board (stop me if I'm boring you).

SO....

A V3 will require 4 x Output Mosfet boards, 1 x 1st Stage Board and 2 x Power supplies.
A V2 will require 2 x V2 Combination Boards and 1 x Power Supply.

Firstly if someone can check that for me.

Secondy, the cost of a test batch is prohibitivly expensive (then again so is getting the boards wrong).

I could really do with some of you experts to review the boards against the schematics. I really don't want this to go wrong.

Oh, forgot to say.
All the boards have alternative resistor positions for Caddock and Futaba resistors.

UKToecutter · 22nd February 2012, 02:20 AM

So here are the boards

1st Stage V3 board

V3 Output Board

PSU Board

V2 Combo Board

Time for bed.....

This monoblock configuration would work for a 180 watt F5-turbo.
The dimensions are 15"x11.5"x6". It might need to be slightly larger for the bigger toroid transformer. I have actual temperature measurements for 2 x F5 channels at 65W dissipation per channel with only 12C-14C temperature rise.

Wonderful work Andy.
Not necessarily split N & P boards. I would just use 2 of your output boards in parallel.

V3 per channel: 2x Output board, 1x 1st Stage Board, 1 PS board. Preferably in one mono block

V3 stereo: 4x Output board, 2x 1st Stage Board, 2 PS board. Preferably in two mono blocks

V3X per channel: 4x Output board, 2x 1st Stage Board, 1 PS board. Preferably in one mono block

V3X stereo: 8x Output board, 4x 1st Stage Board, 2 PS board. Preferably in two mono blocks

Oh...
V2 stereo 2 x V2 Combination Boards and 1 x PS board. Stereo chassis is ok

For checking the layout and schematics there are better experts here.

Any news from Papa regarding his OK?
