Okay, this isn't about guitar amps, but about a Zenith Trans-Oceanic SW radio that I am restoring. I am in need of some electronics advice and figure why not ask the smart people on my favorite forum? The radio in question was built in '49 or '50 (I forget which at the moment) and uses the miniature vacuum tubes including a 1L6 tube that has become rather expensive due to hoarding. Last check, it ran between $45 to $75 for a good tube. I have seen worse in the guitar amp realm, but it hurts just the same. Along comes a guy who sells a Solid State version built into an old vacuum tube. Basically, he took the SS design from the Zenith radios that ended up replacing the tube radios and built them into old glass tubes so they can be just plugged into the socket. The claim is that the specs are nearly identical but with the longer durablility of the Solid State design so you don't have to keep chasing the long discontinued 1L6 tube. Price-wsie, they are about the same price. What scares me a bit is that you really have to consider this an experimental design, but I am not sure what could really go wrong if it failed? I guess you miss out on the tube glow, but these radios are low watt (1W) affairs anyway, so the glow wasn't all that prominent. I also plan on adding an mp3 port to the chassis so I can just play old radio shows and sports broadcasts through the radio out on the porch in the evenings. I know, very nerdy, but that's me. Just looking for some 2 cents advice here.
