This one has the AM filter as well as the SSB and CW filters. I evaluated this one for the museum, VRCMCT.org, it needs alignment and does not work well on all bands, maybe dirty switch, not sure, maybe something else. The mentioned hum is minimal. The tuning dial does slip around 70 on the dial. It has no power cord, which is similar to an old style tube tv power cable.
