Got everything wire up and ready for testing but...
Having trouble programing the Atmega and going to give up for today.
Can any one recommend a cheap programer ? the one I have is one made with just some resistors on a DB25 plug (isp programer).

Hi,
You need a programmer that can program FUSEBITS !!!
look for USBasp like this
or check bay for a AVR MRKII / USBASP
atmega is default 1 Mhz in clock in most of the code we have clock 8 Mhz

Hi FarmTech
Found USBASP on the *bay
Ponyprog does fusebits.
I have the freeware version of Bascom AVR but apparently it doesn't take files bigger then 4K and I really don't want to pay for something I'm only planing to use once.

Instead of using a transparent CD case, i use a glass for the window cover.

If you only burn the bin or hex you do not need something else , only for compiling more that 4K you need licence .
You can ask someone that have licence for Bascom to do the firmware and you only program using Bascom and USBASP .

Is already included in current firmware v3.5
There are two open collector transistors for amplifier/preamplifier power On/Off and tube plate delay (see schematic J7 connector).
All you need is to connect them to an adequate relay.

Regards,
Tibi

Yes, but choose the proper relay up to your amplifier power.
