Price Gouging

I was looking for a matched pair of 5751 pre-amp tubes for an upcoming project. A month ago - before Russia invaded Ukraine, they were readily availab;e for about $40 plus shipping. Now I looked and I was shocked at some vendors. For example, Vivatubes listed matched pairs in the $120-$140 range. Outrageous.

I went to my usual reliable sorce - Doug's Tubes. Doug Preston was much more reasonable. Under current circumstances, price increases are understandable. He had a matched pair of Sovtek 5751s for $53 plus shipping. I received them four days after ordering. Thanks Doug!
