Radio Alignment Troubles

[vortalexfan]

Hello everyone, I just recently finished electrically restoring a 1934 Stewart-Warner R-110 Tombstone Radio (replaced all of the original paper capacitors and replaced 1 original electrolytic can cap and 2 1960s vintage replacement electrolytic caps), and I need to do a realignment of the tuner but the problem is that the radio's IF Section uses an IF Frequency of 177.5 kC but none of my signal generators I own go below 300 kC (I have a 1970s vintage Hewlett-Packard Signal Generator with a built-in frequency counter, and vernier style tuning knobs for frequency selection, that only goes down to about 442 kHz and a 1952 vintage signal generator made by Precise Development Corp. of Oceanside, NY a model 610, that only goes down to 300 kHz (.3 MHz), and I was wondering if there's any way to make either of these signal Generators go down to 177.5 kHz or a harmonic of that frequency that the radio would be able to detect that I could align the radio's IF with and have the radio still function as if it had been aligned using a 177.5 kHz signal? If there is, what's the process?

Thanks for the help in this matter.
