I looked at the schematic for the philco , which is posted at Nostalgia Air , and I like the fact that it uses the 50X6 rectifier in a voltage doubler configuration ( a lot of designs just tie the two diodes together as a simple half wave rectifier rather than using the two diodes as a doubler) . Kudos also for having the sixth tube (the RF amplifier separate from the Osc/Mix) as most small series heater sets are only 5 tube . I kinda like the use of the Loctals (all but the 35L6 audio output are lock in tubes) but I do understand some folks aversion to them . The 78 only thing is gonna be a predictable factor for anything that old , 33.3 RPM was out in the times that saw most of these small players using the 7 pin mini tubes by then (35W4 , 50C5 , and so on)
Talk them down to $40 or $50 and have fun with it
