Ok, just done as all of you adviced.
First of all let me apologize for posting this in Towertalk,
I have now subscribed the Amps mailing list as well.
Now to the conclusions:
A) Yes the Ameritron open air relay system is a poor
piece of work, as soon as I opened the Linear and
touch the relay I had imediate changes in reception
levels.
B) I cleaned the relay contacts
C) I did resolder the white wires going from the PL chassis
connectors to the relay.
D) I tryed to align the best I could the relay contacts, but this
open air relay that Ameritron send me seems badly fragil
(worst than the original one), as soon as you touch it your reception
goes, even if it is a slight touch.
You were right it is the Linear Relay.
Now after all this, the AL-1500 seems to be working properly and
until now I had no more problems, lets see how long it will hold.
Thank you all for your help.
