This was the W1GUH AM rig. with the GPR-90 and the Eicos on top of that.  To the right is the audio chain.  On the bottom is the McMartin Universal Amp. used as a Mic. preamp, the EQ and the Auidmax is above that.
A better view of the audio rack next to the  4X1 Rock Crusher.  They told me AM Linear was inefficient...hoo boy! is it.  Had to use all of the 4X1's dissapation and then some to get 500W of carrier.
