Heathkit Service Bulletins - HD-20 (Revised & Complete)

[Joseph W Lutz]

                        August 10, 1973
HD-20                                           Bulletin No:
Crystal Calibrator                                      HD-20-1

                               Battery Shorting To Case

In some of the older HD-20 calibrators, there is a possiblitity of the
battery sliding in its clamp, shorting to the case.  This can be
eliminated by installing insulator paper [PN 75-93] on the inside of the
case, directly off each end of the battery. [2 required].

Thats everything I hold up to 1989 that covers the HD-20 Crystal
Calibrator.
