Fw: [AMPS] Low B+ on Titan 425

[nospam4me@juno.com]

Hi Stan, 
-
Like Phil, I agree that the filter capacitor bank would 
be near the top of a list of things to check first.  I have 
repaired a quantity of Alpha amplifiers with similar 
symptoms, but not with open filters, mostly shorting or 
temporary shorting caps.  
It  was interesting to note that some of the amplifiers 
would operate at the lower plate voltage, others 
would trip out the breakers right away.  The more 
strange problems were the caps that would fail after 
a variable on time, then go back to working with 
power removal, then fail well into the next operating 
cycle.   More gray hair...

Haven't used my Titan for some time and when I powered it up to use, the 
panel meter shows the B+ as just under 1800V not the 2200V the manual
says 
it should be on high power.  it is also indicated as being 1250 or so on 
low power.  Any thoughts on what to check first?  By-the-way, power out
and 
general operation are consistent with this lower B+.

Thanks & 73
Stan, N3HS
