The most important parts. Well, not that the amp would work without wire, but these are the parts to fit onto the chassis!
And this is the chassis in progress.
Once the sides were bent, it was time to see whether the parts would fit. Or: daydreaming, imagining what this thing would look like in the end.
The two PIO caps and the 6H choke were painted black to match the power transformer.
A wooden enclosure made from eucalyptus (actually leftovers from Phylira II ;-)
The metal painted and the wood lacquered in the 'typical' UltrAnalog style...
Inside some supporting rods to keep the enclosure strong. A bunch of rings that I dropped in the enclosure. I could catch either my camera or the rings falling...
And then it was time to wire the insides.
Close up of the inside: driver stage (battery bias) and HV delay relays.
Testing & measuring. Check the heaps of wire... Apart from functional behaviour, also a lot of tweaking was done. At this point I decided to try an improved driver stage setup.
