I have a Fada 1001 with an extra RF amp, but I do not think it is tuned, the usual approach was for the output of the RF amp to feed into the grid of the mixer section of the convertor tube via a capacitor, sometimes with a choke in series. I will have to see what they did in the Fada, it's been a while since I overhauled it.
