We are rebuilding a couple of Marantz 10Bs. We're going to replace all the 'lytics and replace the output coupling caps with with Russian Paper in oil. We're also going to bypass a cathode bypass cap with a Russian Paper in oil.
The original diodes in the demodulating circuit are UG1007. What the heck is the difference between them and the UF1007, and should I replace with UF1007?
Are there any other mods recommended?
