FS: From the 60s an EICO tube and transistor cHecker. Calibrated less than a year ago. When you buy a tube tester, the first thing you have to do is send it away for calibration. NOT here. This unit is ready to go out of the box. The only errors I ever got were from operator error. When I had set a switch wrong. Comes in it's own heavy duty case. Not pretty, but very strong and clean. These cases never were pretty, They were meant to protect the unit. This one was factory made. The wiring is still awesome looking. Complete with ORIGINAL instruction manual and tube chart. This unit is designed to test every kind of tube and transistor available in it's day. Even odd ball tubes like nuvistors.. Unit is very heavy, SO, well packed UPS or FedEx only. Price is $400 shipped to your door, CONUS 48 only. Ready to use, no extra calibration time or cost. This unit has been well cared for and shows it. No scratches or dents. I Take PayPal,USPS MO, or personal check with a hold. If you want to discuss the rig, send me your phone number and I will give you a call at your requested time.
