Still got parasitics. Avoiding them is a craft in itself.

I wouldn't worry about the inductance of an ordianry 1/4 -Watt resistor
at the frequencies involved.  The only point where it might make any
difference is the VHF input and oscillator tuning - and I can't think
you need a great level of accuracy to align a domestic portable radio.

It is even possible that they specified a 60-ohm sig gen because they
knew that most of the available ones would be near enough at either 50
or 75 0hms.   Another possibility would be to try to make you think you
had  to return the radio to their specialised service department for
repair.   The avarage radio shop (if there are any left) simply wouldn't
care and would use whatever they had on the shelf above the workbench.
