[R-390] RE: [R-390] My 'new' '67 EAC is now "on line" 8^ ) Ballast Tube question.

[Phil Atchley]

Hi Ed.

Bingo!  You hit the nail on the head.  I just took the screws out of the
front panel (again) and took a peek at the Ballast tube.  IT IS a 3TF4!  I
didn’t even think about the possibility that it had the wrong tube in it.  I
rechecked the Voltage across the output of the ballast, going to the BFO and
VFO and see 11.5 Volts tonight (think I had just over 12 when I checked
before).  

 

Well, since it’s what’s in there and it isn’t applying too much Voltage to
the tubes I think that I’ll just run it till it quits 8^)

 Check that you've got the right ballast in there also.  I experimented with
a 3TF4 when I didn't have a 3TF7.  It functioned, but it lit up all over- I
expect it would not have lasted too long.
