[Hammarlund] HQ 140 X arrives!

Tue, 23 Sep 2003 23:57:47 -0700 (PDT)

To get in the top, undo the two lamp holder screws, and two screws on the rear top of the cover,
you can just put back the tube holders with screws to stop things going astray.

Not a lot to see, realy, you can clean up the bushes and blades etc.

There are a couple of caps and resistors in the RF section to check but nothing special.

Good rig eh? I have a HQ-120, 129, 140, 150, 180 and a RBG-2
