KITS just about ready
The power amps = 5W SECA, 15W PP B class, 30W A/B all design based on chassis from Amazon.
The complex and bit was to design a PCB that did all 3 version thus reducing R&D cost from thousands to £500/
SECA Pre being done now by Quickie.
Normal Pre ready just trying to find nice chassis
The Amps are all leaded no SMD.
BOM and cct available on request.

Whats the Normal Pre Col ?
Are you still planning a headphone amp?
5W SECA sounds amazing caps 2 off 47,000uF
SECA A/B amp caps 2 off 22,000uF 5W class A 15W class A/B gives 18W Build this one Paul I put mine in chassis you sent me THANKS
A/B 15W Amp caps 2 off 10,000uF gives 18W
A/B 30W Amp caps 2 off 10,000uF gives 40W
Tested on Mintrals and Ruark Sabre, all stereo.
When next chassis come will do bridge balance in version at 80W A/B 10W A class.
When you come to set them up A/B bias first at 100mA and SECA at 1A.
Also adjust DC bias to less than 1mV
Have fun
Looks like Dave is building all four
Sorry. Thought I'd replied. Ooops!
