I thought about doing just that but unfortunetly it seems the audiohhhphiles have created quite a demand for a few of these. As an example the rectifier was selling for anywhere between $50 and $150!. The triodes and the power amp tubes were the ones that were really nuts as they were types in demand for the high end stuff. I was thinking that they might have been worth maybe $5-$10 etc as I can buy sovtek 12ax7's locally for $12. Be waaaaay cheaper to find a tester or just build a chassis for the ones I do have. Dave -----Original Message----- I am not sure in Canada, but here in the EU you can still buy some tubes -- which may or may not the same as you have :-) but might be a good start. Some people still prefers tubes in high-end audio amplifiers. Tamas On 11/14/06, Dave King wrote: > > > Not sure if l saw your post.
