[Elecraft] OT: Help me identify this capacitor?

[W3FPR - Don Wilhelm]

Richard,

That is a 4700 uF 150 volt capacitor.  You may not be able to find an exact 
replacement, but do check the mounting and the size that will fit.  You are 
seeking a replacement capacitor that will fit into the available space and 
can be properly mounted - the capacitance should be somewhere near 4700 uF, 
but the voltage may be 150 volts or higher.
Mouser does list several that may be close to what you are seeking. 
Mouser's 539-CGS200V5400 or 75-36DY472F250CD2A or 75-36DX422F250CF2A are 
possibilities I ran across - do check the physical size carefully before 
ordering, those large capacitors are quite pricy.

73,
Don W3FPR
