for sale: pair of rare vintage 5751 tubes labelled Arcturus. Triple mica, grey plate. Tested with a Heathkit TT1A tester at 1200/1200 and 1400/1100 where minimum good is 780. Old tubes - but guaranteed to work (test results not guaranteed to match, of course). Sold for use or collection. Non-original boxes. 5751s are direct replacements for 12Ax7s, though with slightly lower power level. 5751s are considered quiet tubes and often recommended for use in phono applications. These were likely made by GE or Sylvania. The Arcturus label is hard to find on 5751s. $5 to package and mail in US. please contact me for shipping quote to other countries. Thanks for looking.
