He offers a slightly different board made for the AC-4.   The 
"Twist-Lok" style of capacitor such as used on the AC-4 is all but 
extinct these days.   Here you have new PC style mounting capacitors, 
new diodes and resistors.  The only other option is to install axial 
(wire lead) capacitors under the chassis of the AC-4.   Axial and PC 
mount capacitors are available reasonably from Mouser and other 
distributors.
