UPDATE
Man!
I have not checked this post in awhile, It now seems to have turned into a "Soap Opera".
Oh well a fun read indeed.
For what it's worth.
I also own a older Whites Spectrum XLT that has served me well over the years [ tho it still likes to chirp ,when the loop strikes a tree ,rock or fallen limbs. ] this is something about the tejon I really like, cause it did not do that, all my Whites machines seem to have had that same trait.
Minelab machines are too much DOLLAR (for the kind I want) at this time of many other wants/needs .Like A Quality Safe or A high end AK-47 or Dependable AR-15 & I,m always in need of another Pistol.
Ill save the Gun Talk for another site.

My tejon has /had 'hopefully" all the symptoms your machine does , except it would ground balance
UNTIL my Father & I took the plug apart then stripped and re-soldered all the wires in the plug.
After that was done the machine was still chirpy but not as much .Now I could not get a stable tone to ground balance the machine....So I sent it off
On friday the 7th of March The Tesoro tech called me and said my coil was bad ,I asked what caused it ,then he mentioned Dad working on it and asked did he mess with the connection where thr coil wire goes into the coil and I said no. He paused and said I don't Know but it seems the innards of the coil are bad.

Rusty I think was his name & He was a very nice guy. as were all the people I spoke with at the Company.
Since I was not the original owner I chose to buy another coil (at a discounted price).
It hopefully shipped out on Monday the 10th ,So i,m waiting for it now & will let you/everyone know how it works.
Good Luck
