Tom, I'd love to see your Philco

For changing the transmission standard this set has 12 selectors in the back, with 4 positions for european PAL, belgian PAL, french SECAM 625 lines and 819 lines. After I select a channel with another standard many relays change their position for detect the new transmission with the proper circuits. A bigger relay under the EHT cage change the windings of the flyback for 819 lines transmissions.
