The store (Lechmere Sales) in whose audio department I worked in the mid 60's carried the ADC line. They were in the same bracket as those of Fisher, HH Scott and AR's. I liked them better. I don't recognize the ones pictured, tho.
Their TOTL phono cartridges were, IMHO, among the very best. I still use their XLM MK III and actually found a NOS replacement stylus for it (and a cartridge, too, which I bought, as it was only a few dollars more than the stylus) at the NeedleDoctor.com. Whoodathunkit.
