McCurdy Audio Boards

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.

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 where they enter the headset or at the plug end, but easily replaced  and the molded plugs have been removed to save shipment weight. Excellent low cost headsets for projects.

Only 4 left & were $5 ea. but
the last 4 are now only $10.

(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.)

HP115 Listening Station

10 station system with 8 headsets

 FREE

This nice wooden case is free when you purchase the 8 headsets inside it for little more than $2 each.
- or -
how about the case PLUS the 8 headsets for FREE when you purchase the eleven 1/4" phone jacks for less than $2 each.

A Good Deal Either Way

Qty: 1$20

Update: I found a use for the wooden case so only the headsets remain available. (Just as well as the weight of the case would make it costly to ship.) Each earphone is ≈ 400 ohms for a total headset impedance of ≈ 800 ohms and each headset is terminated in a 1/4" phone plug.

All 8 headsets are now just $10.
