Recently acquired a HP 735A DC Transfer Standard. Replaced some caps, but its otherwise clean and has since been powered. Read a post recently about a 735A oven failure that included a teardown that revealed why HP states the oven/ref assembly a non-serviceable part. The failure in this person's device was the heater, specifically the thermistor.

Anyone on this board have a 735A in use? Do you keep it powered 24/7 or as-needed? Any failures/repairs/mods?

Best
