An old radio brought back to life
The patient the author had to revive was a Telefunken model T 33 B RFS broadcast radio in a wooden cabinet, fitted with a turntable, and made in Italy around 1953. Lots of Internet sites offer circuits for these old receivers, so I had no trouble getting hold of one for it. The Internet also enabled me to download the datasheets for the valves it was fitted with.
