I found these resources today while trawling for a .pdf manual for my Eico 250 VTVM:

Re: Interesting findings on the internet
EICO was a most worthy competitor to Heath. Sadly they went the way of the dodo too. 
Edit...EICO also sold audio kits but I don't see them in that catalog. Perhaps it was a separate catalog. I do have an EICO catalog somewhere in my stash along with dozens of Heathkit catalogs.

Re: Interesting findings on the internet
I always thought EICO was a lesser manufacturer of TE, not a kit company. We don't see EICO much this side of the pond. Heathkit/Daystrom was well established here and they had a factory in Gloucester. Heathkit turns up regularly at swapmeets here. I have a few units; a VTVM, a distortion meter and an audio wattmeter. There were a few other companies of that sort. Jason and Knight come to mind. Those sort of companies, like electronics shops aimed at hobbyists and hams, were things of a particular era.
