There is a very nice looking SX-115 that they are asking $1500 for.... I wonder if anyone actually pays that kind of money for vintage rigs with or without knobs...

In some instruction books there is a note about the meter used but not always and sometimes it takes some detective work. For instance, the Hammarlund SP-600 has voltage charts that used a 1000 ohm/volt meter for DC and a VTVM for bias/avc measurements. The VTVM is not specified but was probably about 10 megohm. The readings made with the 1000 ohm/volt meter are significantly different from those you will get with a 20K ohm/volt meter or a VTVM. Because the source resistance of these circuits vary one to the other there is no constant correction factor. However, if you use a 20K ohm/volt meter you may be misled into thinking some of the voltages are too high. I have an old military meter that has both 1K and 20K ohm/volt divider strings, which is sometimes helpful with older equipment. If there is no note about the meter type or specs you may have to measure with both kinds to see if one is consistently right and the other wrong. In some cases, like the AVC and bias lines, one MUST use a VTVM or electronic voltmeter with very high input resistance in order to get any sort of reading that makes sense and not disturb the line. In the case of some sets I use a Hewlett-Packard 410-B with its 122 megohm input in order not to disturb the voltages. Rider's and Sam's are partly reprinted from manufacturer's data and partly made up by the publisher so they can be more confusing than helpful.
