[QUOTE="N61753, post: 102363, member: 3834"] Thanks Condor22 good catch, absolutely right. I hadn't thought of this. I know they are very high impedance(resistance). If I find they still are in working order will make this into a project and post my results. Will use an impedance matching transformer and some type of volume limiting circuit. Thanks Outboard, you got me thinking in that direction. I'll try an make it a proper project which others can use, but then again the phones are probably faulty. If anyone can recommend a volume limiting device I would appreciate it. I know you can do this with an operational amplifier. Would like to come up with something everyone could build with a cost of $10.00 or so. [/QUOTE]
