Ed: Have the SS-1R, along with the SS-1V panadaptor, the matching speaker, and SS-1S noise silencer(actually have 4 noise silencers) for about the last 10 years. Great receiver and the panadaptor works well with it. Only the Clegg Intercepter uses the 7360 as a balanced mixer. The SS-1R uses 2 7360's as 1st and 2nd mixers. There is no RF Amplifier stage. National's NCX-3 and NCX-5 used a 7360 in the balanced modulator. The second iteration of the NCX-5, the MK II cast aside the 7360 in favor of the more conventional solid-state diodes in the balanced modulator. You're correct that power supply requirements, lead dress, and tube and component aging moved them away from the 7360. Swan and Gonset also used this tube. There are several beam defection tubes in circulation during the 60's time frame. Unfortunately, none of them are directly interchangeable with each other unless one is willing to rewire several pins on the tube socket. Spec wise they are very close to each other.
