Butler TDB2250 250 Watt Hybrid T H E R M I O N I C
Vacuum Tube Driven Stereo Power Amplifier
2nd Owner of Butler Audio TDB 2250 that I bought some years ago on AudioGon and has served me very well but moving on something new. Usually never have components more than 2-3 years but I've had this the longest through 3 sets of speakers. Rating conservatively 7/10 since I'm second owner but unit is in excellent condition. Have only had to replace fuse once about 3 years ago. Asking $1,250.00 (New $3,000) plus shipping. Shipping weight is about 45 lbs. PayPal only and will only ship to continental US. Will take more photos of unit after pulling unit out of rack and prior to boxing unit up to whoever the lucky buyer is. I still have the original box and will include a standard power cord.
Please be patient but I don't check this but
maybe once a day but will respond to inquiries in chronological order. The following is pulled from web site.
