Hi,
one question came through my mind, recently. What would happen if I would replace all passive Parts in my Tektronix 2225. It is working fine but it will turn 30 years and especially the electrolytic caps will not getting better with years. The same happens with Carbon Composit Resistors, but not so obvious. So ...will the Oscilloscope profit of such a overall replacement with newer even better parts (thigther tolerances, lower tcr, metallfilm instead of carbon, maybe low esr Caps etc)? (except for prolonging the Scopes lifetime) Such as SNR, accuracy may small gain in bandwith.
(replacing semiconductors will be more difficult - ....maybe diodes with better specs)
Thanks for your suggestions in adnvance
Best regards
Alex
