SF-88 Launcher Elevator Time Delay Relay Replacement.
from Greg Brown, May 18, 2015
Several years back, Historic Nike Missile Site SF-88 volunteer Alec Gyorfi told me they had problems with the old pneumatic time delay relays in the elevator control cabinets. They were failing, or could not maintain a consistent delay time. Direct replacement relays were hard to get and expensive. The elevator controls are dated 1954, which makes them 61 years of age.
Greg Brown and Alec had looked at some solid-state replacement units. An initial test in B-Pit with some solid-state units purchased on EBAY. They worked well. We submitted an order to SF-88 Ranger Al Blank for replacement units to retrofit both A and B Pit elevator controls. They were received in record time for government work, (one week). They were installed on May 16, 2015
