Did my 1st-ever re-cone!
« on: February 26, 2017, 12:26:01 am »
Weber 15F150 (30W) with a rubbing coil (internal bubbling due to overheating). Uprated it to a 50W coil with a kapton former. Took me 5 hours all up.
A bus stops at a bus station. A train stops at a train station. On my desk, I have a work station.

I got 2 JBL 2035's in my future, both coils are good, just big ol holes in the paper.
Went Class C for efficiency

That is the ticket. The key is being patient.

Test fired it this morning on one of my home-brewed t-bolts. Yay! It works!
