Hi Al, will have to get more info, on more modern valves, for substitutes. The only thing that niggles me is the coil pack removal with waveband switch, not making any mistakes, the caps must be up for renewal as must a lot of the resistors, due to value changes leakage etc, then after all a good re-alighnment, i have several sig gen,s, even avo all wave oscillator 1930,s vintage working very well and quite accurate. I have two CR100,S both working but in need of refurbishment.....kind regards.....Alan.
