[ForSale-Swap] Grid-Dip Meter Rebuild

[Ian]

Too bad to "ruin" a nice GDO like that by trying to put in Solid State.  If
you're going to do it perhaps you could make it easily reversible.

I was turned off by solid state GDOs when I bought a Heathkit tunnel dipper
in the "olden days" and it was virtually useless and I brought back out my
old standby tube type Heathkit GDO.

Maybe the solid state ones are much better but I was never willing to invest
money to try except for an attempt to build one from a construction article
in one of the ham magazines and again I went back to the tube type Heathkit.

Greetings All,


 Dose any one have any thoughts on converting and old tube type Grid-Dip
meter to Solid State?. I have a Millen 90651 GDO that I purchased back in
High School, it still works well and I use it often on the bench. But now
with the weather turning warmer I want to be able to use my Millen Antenna
Bridge out side. And I am getting tired of pulling an AC extension cord out
every time I want to play with the antennas. I purchased another 90651 from
the " E " place, it has a bad power transformer, but I knew that went I
purchased it. My idea is to strip it down, clean it up and rebuild it along
the lines of the Millen 90652. I have found plenty of information on the
90652, schematic and parts list.
It seems that the tuning capacitor is the same in all the Millen series.
Any thoughts and idea's will be welcomed.
