John, The actual building time was a couple of months. I had a large junke box and had most of the hard parts to get, dial, IF trans from ARC 5s and had the power xfomer. Bought the resistors, the old ones have changed value. The chassis and coil forms are home brew. Check it out on Kees's web. Hi Mike. I did not have the $$$ to build the HBR when I was a kid, but to have a HBR then was a real treat. Jeff
