[HBR] HBR-11/2000. Comments?

Thanks Walt (KJ4KV) and Dan (K9WEK) for the insights on IFs. Progress to date 
on the test chassis (6AR8 mixer-6EH7 if): I was able to stabilize it somewhat 
by using resistive loading of the input and output transformers, and reducing 
the cathode bypass cap to .001 (if freq = 530kcs.) Still evidence of 
regeneration; narrow nose BW and excessive gain. 
Now I try capacitive bridge neutralization. 2.7 mmf neut. cap. and 1500 mmf 
cap on the bottom of the input IF trans. gives me a fairly stable IF amp w/out 
the resisitive loading and normal value of cathode bypass. At this point, 
trace goes south on the old TEK 454a necessitating some down time to fix it. Looks 
like neutralization is the ticket!!! 
Next item on the agenda is the audio amp and B+ supply built on a separate 
chassis
from the HBR. I got some nice solid walnut boards to house the amp/B+ chassis 
and
a six inch commercial PA speaker. I have found that I need lots of loud clean 
audio
for hamming around. TNX ES BCNU. Barney KC8LTD
