I have a pair of Wathen Cryotone 6SN7 preamp tubes with converter bases for 6922 that I have put about 300 hours on in SE84UFO3 Monoblocks, Taboo Mk IV and CSP3. . . and I recognize these are great tubes, but other 6SN7 and other tube types work better for my tastes in my components.

These converter bases are American made by a vendor that Brad recommended here a year or so ago. Very nice bases BUT when I put these tubes into them and then removed them to try another converter base. . .the fit was so tight that the guide pin of both tubes broke and remained in the converter base. So this base can only be used with these tubes going forward. . . . Perfectly operational, the separation of the guide pin does not hamper the operation in any way.

The pair of tubes cost 240 and shipping, the converter bases were 69 dollars shipped. I would like to sell this pair of tubes and bases for 200 dollars including postage within the US. If interested PM here or email me at lonjazz@yahoo.com
