Been checking the waxie capacitors, all are useless, big recapping job coming up.
Apart from the different type of oscillator triode, the original Hartley circuit and components have been retained and operate at 37Mhz. The local oscillator is coupled to the mixer by a single turn loop on the mixer grid coil. All the RF coils have metal cores.
