IV-12 VFD Socket Solution. (Because 10 Doesn’t Fit 9, and They’re All 9.)
After recieving the miniature tube sockets, it was shocking to realize a 10 pin tube doesn’t fit into a 9 pin socket. So, next time count better and don’t assume all little tubes are the same. After checking around, it seems 10 pin preamp size tube sockets dont exist much, if at all.
Digi-Key was also little help. Acceptable pin sockets were $20-40 in cost for 60, for solder tails and proper size compatibility. Socket footprints also complicated things, as spacing between the pins is minimal. The cheap solution: pull the pin sockets out of the unusable 9pin tube sockets. 100 pin, for about $14.
The tube sockets from Parts Express are described as porcelain style. They’re white plastic.
