Am restoring a HQ-140X and need help on two items
1. Does anyone know the value of the RF choke in the RF amp. The manual refers to it with a part number. The one I have is open.
2. I need a band spread dial. Someone put too hot a bulb in mine and cooked one spot badly
Thanks and 73
Carl,
What I usually do if I cannot tell what value a choke is in an old piece of equipment
be it a xmtr or rcvr, is use my trusty ol B&K digital LCR meter and measure the
choke value in a another receiver of the same type design,--in this case an 129X
or 120x has very similar circuitry.(thats if I could not find another 140x) to
compare the inductance value.
Those PN`s in the manual are "useless", as parts from the factory, for these old receivers have not been available for many years.
I have had my digital LCR meter for years, and I find it an "indispensible" item in
determining both unknown capacitances and inductances.
