Thank you both for your input. It was very helpful.
What is a reasonable price for NOS 6H30P-DR Reflektor Tubes?
I have some of these tubes that I bought back in 2010 or 2011 from a dealer as spares for a preamp that I sold a long time ago. They have date codes of June 1986. They are definitely NOS. I’ve searched the internet but can only find listings on eBay that are all over the place…I want to be fair for both parties. I know way back when BAT was selling them for $250 each. Any thoughts? Thanks
