Hi All,

A bit trivial but very common problem...
I got a free 203BA i had to remove from a tower. It has been there for
years.
All parts are OK except that i can't dismantle some elements. Certain
tube junctions are corroded despite some tape protection, and the
elements are like soldered.

Is there a safe way to remove the aluminium oxide so i can disassemble
the elements for transportation ?

I've been told that letting petroleum seep between the elements would
help. But that can take days or ... weeks...

I'm sure, you all had this problem one day and that someone found a
"good" solution.

Thanks for any comments,
73, Patrick TK5EP

I like to use a source of heat like a propane torch to loosen up the
joints. You will need gloves as well, the aluminum conducts heat very
fast...

Hi John,

Thanks for your suggestion.
I'm surprised to receive so few answers to a problem that seemed very
trivial to me...
You can get dozens of answers for a patent problem but only one to a
daily problem that every ham has encountered at least once in his life
... ^^

Thanks and 73,
Patrick

Experience sharing is one of the many positive aspects of the
internet.
The picture on qrz.com is beautiful!
It is going to take a while for me to get all the way through your
website. I hope to work you some day. I am not real active on Ham
Radio but I expect that to increase. The delivery man just dropped off
a new Ameritron AL-80B amplifier today, I am getting ready to open the
box...
