[Hammarlund] Looking for tube shields and 5U4 replacement.

[manualman at juno.com]

Although tube shields are nice, I'm not sure you'll see much difference
between them on or off.
My HQ-170A-VHF power supply has been solid-stated since the 70's. Hasn't
popped a cork yet.
Hammarlund issued several addendums correcting some AVC issues in the
HQ-170.
