Heathkit SB-634 Station Console

[Paul H. White]

I am having some display problems on this unit; any help would be
appreciated.

First, I have removed the display board, resoldered two connections and
reinstalled it, making sure all of the cabling connections are tight.
This improved it considerably, but I am still having the following
problems:

One of the large display tubes (Heath Part No. 411-286) is still
flickering and, from time to time, missing one segment; and

The small display tube (which is the station ID display; Heath Part No.
411-804) has a number of missing segments.

If someone has replacement displays (or knows where they are obtainable)
or, has any suggestions of some other correction to cure these problems,
I would appreciate it.

I would, of course, be willing to buy some display tubes from anyone who
has them at at acceptable price.

Thanks  and 73,

Paul
