The 7868 output tubes are a mixture of vintage US. These all test great and are closely matched. This amp has never had modern 7868 tubes jammed in so the tube sockets are all still tight and ready for you to try different vintage 7868 tubes if you so desire.Has been updated only to be sure it works safely. Bias has been set to the factory setting at about 120vac. An in-rush current limiter thermistor was installed to help save the tubes and get the voltage a little closer to the preferred 117vac. The electrolytic power supply capacitors were upgraded along with a few out of spec resistors.
All film capacitors were left in place to keep the amp as original as possible. 60 years later these caps still test perfect and sound great. The potentiometers and switches were all thoroughly cleaned.The original power switch works perfectly. Many people recommend leaving the power switch on and turning the power on and off elsewhere to insure the power switch keeps working forever. Faceplate has one or two very small scratches maybe not visible in the pictures. It's clean, but could be even better with a little more attention to detail. There is some pitting in the chrome, please see the pictures for the best description. Also, its very slightly indented in the middle. I might not have even noticed if i didnt have another one of these to compare it to. Will be packed extremely well. If you are unsure of how to operate and maintain a vintage tube amp I highly recommend going on audiokarma , or a similar website to at least get the basics down. I will happily answer questions you might have. The item "Vintage Fisher X-100-B Integrated Stereo Tube Amplifier Works Perfect" is in sale since Saturday, April 17, 2021.
