Gentlemen:
I am scrapping-out an old Tektronix 453 oscilloscope. When I got to the high voltage section, a white block of something fell out. By it's position, in the power supply, it appears to be there to transfer heat, from the HV section, to the chassis. Could this possibly be a dangerous block of Beryllium oxide? It has not been broken.
Thanks-in-advance,
