Have not had the time to investigate and find out more about these boards and what connections or input & output levels are. If nothing else, they are a great source for I.C.'s, transistors, regulators, pots, capacitors, etc.

Searches have all lead to Chinese web sites which was of little help. No data sheets have been found for the two I.C.'s, but several circuit schematics were found at http://www.art-audio.com/diybbs1/cgi-bin/topic.cgi?forum=1&topic=601 and http://www.sldzc.com.cn/new_page_81.htm

General AV #6T7

600 ohm Headphones

These came from a Speech Lab and have
two 8 ohm ear phones in series with a 560 ohm resistor to achieve their 600 ohm impedance.

Cords are defective, but easily replaced and headsets can be wired for mono or stereo.

 Excellent low cost headsets for projects.

Qty: 9$5 ea.

(The 8 Ω speakers are worth the price alone and I will even remove them for you to save on shipping costs
if they are all you want.)
