The iPod holder and connector.

The cradle was machined out of a block of aluminum to fit my G1 Nano. Looks like the G2 Nano connector is moved over 2mm so that will not fit without some machine work.

I found lots of mods for this amp in tube amp forums, but I wanted to work through the amp design for myself and improve anything I could.

I really couldn’t find anything that would make a big difference. I bought some extra tubes and used the best matched pair. Some of what I changed is shown here.
