I purchased a Mike Matthews Freedom Amp way back in 1973 in a pawn shop for $109.00. It has a 8 inch speaker. It is a AC/DC model and uses 2 – 69 volt Lantern Batteries. It has three knobs: Volumne, Tone and Bite. Two 1/4 inch jack inputs. It has what I think is a transformer with 2 big capacitors atached to it about as big as my fist (4 inch across). I bought it to use with my accordion for outdoor street jams. I’ve often wondered about the hum or hiss it makes when I get too close to it with my instrument. Is this what is called feedback?? Or is there something going non with it internally? But sitting about 30 feet away from it using extension cords, and just turning the knobs up about a 1/4 inch distance is enough to wake up the dead from their graves! I’ve never cranked it all the way up full bore, I was afraid of exploding my accordion. When I turn it off, there is a lot of electricity still flowing through it. I was afraid of possibly getting a bad shock from it, so I let a local electronics whiz check it out. He put in a kill switch for me to send the residual electricity to a capacitor. In all I’ve got about $200.00 into it. It is a Black Tolex Case in decent condition. I’m currently using it with a battery powered microphone as a P.A. System. Yes, it is still screaming loud as the day I bought it 41 years ago.
Anyone out there know how much they are worth nowadays?
Thanks,
