[Amps] Henry 4K-Ultra Restoration

[Bob Maser]

All the wiring has been completed and now I am waiting on a blower.  The 
stacked German muffin fans only produce .25" of water pressure and the 2 
3000 rpm blowers in my junque box both measure 1.3" and they are LOUD!!! 
I am fortunate to own a genuine manometer that came with a floor model amp 
supposedly built by Lew McCoy so air flow measurements are simple.  Lew 
actually mounted the manometer on the front of the cabinet.  I thought it 
looked neat until a couple of ham buddies cracked up about it. I used the 
actual RF deck with the tube plugged into its socket to make my 
measurements.
