Modifications to a Convectron Mark II Vacuum Hot Table
A damaged vacuum hot table manufactured by Convectron, Incorporated (model number: VHT MK-II MOD I) was repaired for the Pacific Conservation Centre of the Canadian Conservation Institute. The design was found to be marginal with respect to longevity of the solid state relays used. Modifications were carried out to supply each relay with its own proper heat sink and protective fuse. Indicator lights were also installed to warn of blown fuses and resultant cold areas in the table top.
