Slow vertical drift
About two of three years ago I rebuilt a Motorola TS-4J /VT71. Lots of new resistors, all the paper caps, and afew odd things I found along the way. Set worked great for acouple of years and then devoloped a vertical drift probem after about 15 minuntes of use. All voltages around the vert and sycn circuits look good and are steady. Tried frezze spray on the mica caps and also tried heat from a heat gun to get it to act up.
Any ideas? Terry
