 that's right Jim , at the qrl we have been used an RF amp with a couple
7527A's for industrial use .
They are the same as the 4-400 and each year we "pull" them out the amp .
The amp is never been tuned on full
power , he's been used on 500 watts .

and gess what they are doing with them ???? yep trash .......
Untill there was a ham ( that wass i ) passing . and now each year the pulls
are mine .

A few weeks it was even nicer : i have the pulls , i have a pair brand-new
tubes , and next year i will have the complete
amp . He will be replaced for an solid state amp .
The amp is an HFS1000D  RFPP .(no not with an 3CX........ but 4_400's)
