Matched pair Raytheon 5751 Windmill getter black plates

Further Information:  These tubes were bought as NOS from a respected audio seller from O/S.   I paid close to 500 delivered to Aus.  A fantastic tube,I used them for around 100 hours but ended up spending more money on Mullards which suited my system slightly more.As you can see,most of the writing has come off the tubes but this is a common occurrence.

Manufactured in early 60's,these are highly regarded and some think the best 5751, 12Ax7,ECC83 ever made.  Cant mistake them as they have the windmill type getter.

No longer required as I'm not using a tube dac anymore
