For my next oscillator, I would like to use Kapton for the two capacitors. The one around the coax is more just for safety in case the magnet wire chips and shorts. I don't want DC getting into the equipment.
Also shown is a small chip of Ferrite from a broken core. I played with it off and on but have yet to use it. Its interesting to just move it near the parts and see the effects.
There are two longer wires that supply a sort of reference for the transistor. There is another long wire that lays over the top of them. Once the new parts arrive, the plan is to cut out a section of this wire to form a gap and solder the transistor to the two remaining legs, one per lead.
OP here, calm down guys, it's all fun and games. ![Fighting :box:](https://www.eevblog.com/forum/Smileys/default/fighting0030.gif.pagespeed.ce.H3HVtgjLEV.gif)
They were just upset over another thread. I've never seen them post anything technical and doubt very much you will see an entry unless you allow them to use their 555 timer IC.
When the coaxial connectors start to cost $1k or more apiece (1mm connectors), it's too rich for me. I'd like to work up to 40-50GHz eventually but that's it.
I don't know any hobbyist that could afford $1000 connectors, let alone the equipment that uses them. What are you wanting to do up at those frequencies? There may be some interesting physics experiments you could run.

Added pictures of trimmer. Stub will ride in the notch.
