Tnx guys for all the help. Will let you know in next few days whether smoke; no smoke/no signal; or whatever. Need first to get into it and clear out any critters that might have made residence over the years. 73, Steve

I have a variac and can bring up the filaments and then the HV slowly but wondering what is best procedure as to time to allow and increment steps to rebake or reoxidize these tubes, plus any other procedure I should use with respect to any other aspect of this rig, like first oiling fan bearings, etc e tc. Thanks very much, Steve K1PEK
