[TenTec] Popping Noise from Orion and Centurion

[Robert Carroll]

Tony-

Hopefully it's not the relay with such a new unit, but I have had two
Ameritrons with open frame relays fail that way.  So far I have not baked
the PINs in an Alpha 86 or Alpha 89 yet, but that is the favorite mode of
failure for them. They are really nice amps.  The thing I like most about
the AL1500, though, is that it is simple enough for me to have a shot at
fixing whatever goes amiss.  Some of the circuitry in the Alpha's is complex
enough that I usually send them back when a repair is needed.

By the way I noticed with the Alpha 89 which just came back from a checkup
that they noted the RX loss of the amp as .19 dB at 14 MHz.  That's the
first time I have noticed an amp speced that way.  Perhaps my Ameritron
experience caused me to notice it.

Good Luck!

Bob,   Thanks very much for your input.   You bring up some very good
points.  The Centurion is only about one and a half years old,  and I would
have never guessed that contacts would have been dirty.  The Centurion uses
a reed relay input, Potter Brumfield mechanical relay output.   


Again thanks for your input!     Toby  W4CAK
