Technical data
Probably the two models hk 780 and hk 890 were never put on the market or then only in very small quantities, because these devices do not appear on the used market and there are no pictures on the Internet. Was it originally the plan to get into the so-called receiver War and was then dropped - because it was too late and for cost reasons? Thus, the hk 670 was the top model of this device series.
