[R-390] That's more like it!!!

[Jim Brannigan]

I agree, use the parts that make the radio work.  The new parts are much
better than the originals.  However, I could not resist the challenge of
re-building the power supply capacitors in their original cans.  It was a
lot of unnecessary work, but I'm glad I did it.
I ordered the "Experimenters" kit of 1% metal film resistors from Mouser.
To my dismay, they use a completely different color code scheme and the
colors are not as vibrant as on the old resistors, they to be inspected
carefully so the right value is selected.
