avguytx Posted August 22, 2018 Share Posted August 22, 2018 6550's are what my VTA ST-70 runs and I believe I still have the Russian tubes in them that Bob includes. Man, if this was a quad, I might have bitten! Although I wouldn't be able to use them for a couple/few more months. GLWS, Jim. Quote Link to comment Share on other sites More sharing options...
