Does any one have a spare thermostat for an HP 5970 MSD for sale or donation. I am a graduate student who is putting together a research laboratory for my independent career. I almost have the MSD operational, but the thermostat overheats and trips the over temperature shut off once the manifold temperature reaches about 200 C, making the instrument non-functional due to not being able to keep the ion source and manifold at the proper temperature.
Thanks,

David
