Matched pair of 300B tubes. Purchased from Tube Depot which does a great job matching tubes. Have less than 10 hours on them. Just clearing out my tube stash, I prefer Meshplates in my amps. Have boxes,packing, and test sheets. $150 a pair. Will pay shipping and insurance.
The JJ/Tesla are a nice tube, its just these are now extras in my system.
Would consider trading for a pair of good used Sophia 300B Meshplates
