Tom, Thanks for sharing the photos. Comments It looks like most of the items will clean up very well with a bit of TLC. Tom it may be you actually who wrote about the clock and getting it working. Either way I am pretty sure Eric can find helpful details before he applies power. The same goes for most of the rest of the gear. The old caps may have a nasty surprise waiting. Eric the WWVB receiver will no longer work with the new WWVB modulation format. I assume it was a typical TRF radio of the 1960-70s vintage. Good luck Regards Paul WB8TSL
