The  bandswitch  in the L4B  looks flaky enough to me. It has a solid  
detent... but the switch contacts are still not 
huge.. and not  paralleled.. like a SB-220.  


****** True the L4 band switch is not paralleled but the contacts are not  
skimpy thin, they are like the contacts on an open frame relay. (one rated 
for  20+ amps)








##  A buddy across town   built a single 3-500z  for 6m.. works good... abt 
500w .   He  wiped out the neighbourhood
CATV... and that amp was relegated to FD  use.  He also wiped out the 49.9 
mhz  cordless phone freqs at the  time.  This
was 10 yrs ago. 
***** Well, if it only made 500 watts nothing was tuned right, there is  
still another 500 watts in there.  Tune it right and you'll get the power  in 
the right place not on cordless phones and CATV.



later.... Jim   VE7RF
