Nope, you have your email blocked. I might too, I'll unblock it so you can contact me.

Alright, I have 3 boards left with mods I care for, in case someone is interested. I am asking for $70 each. If someone is interested to buy a board, please PM me.

Here a short summary of the changes I made.:

- added option for Optical Out with Buffer IC and decoupling Caps.
- moved power configuration to make some room
- moved fuse holder slightly
- moved Regulator components IC U11, C47, C22 to get clearance for installation in case
- changed capacitor footprint to accept different capacitor pin spacing
- moved the transformers closer to each other
- repositioned Crystal and C34
- added option for LED1, R33 (I like to see if the unit is powered)
- put a trace underneath the D/A chip, 0 Ohm R28 can be omitted then
- added a MCP120T as Gary had suggested
- added a relais to power the headphones with delay and modified the code to do the delay on.
- and changed Label to HD-1.25 to up-rev it.

Cheers

Kay
