When challenged on his assertion that the 3-500Z was re-rated by Eimac 
for 500mA , Mr. Rauch said that he would post the Eimac letter 
authorizing such.  This was around three years ago, and we are still 
waiting. We have been waiting even longer for the letter refuting the 
Eimac HR department's information that Joseph 'Buzz' Miklos, Mr. Rauch's 
alleged "R&D Engineering Manager" at Eimac's SLC facility was an 
-  I have never seen a spec sheet from an electrolytic capacitor mfg. 
which ignored capacitance in determining equalizer resistance.
