Tube tester recommendations

That Amplitrex unit actually tests at full voltage levels, which gives me much more confidence in a diagnostic than partial voltages. I like the digital mutual conductance readout too. The Hickok tube testers have always been highly regarded, and very accurate.

Jafox I made a poor diagnosis of a problem thinking it was tubes and not the combination of power cord and PLC.I never thought or stated that it was the Calypso.I feel the Calypso is the the centerpiece that I am building my system around. The tubes I switched were in the Raysonic 168 which is the weakest (?) piece in this system,I meant to imply that the interaction of multiple tubes in multiple pieces of equipment presents a Pandora's House of posable combinations. I don"t consider this a random choice "Amperex 6922, PQ, white label, US (shield, gold pins) Another very good Amperex tube. Warm yet lively, focused, grainless and transparent. A winner one of the best. Dynamic with punchy bass to boot...." I consider it a good first pick.

Rodman99999 thanks for the imput

Samhar- The Amperex tubes(whatever family) are always a reliable choice. If you enjoy focus, dynamics, ambience retrieval, grainless highs, transparency and extension in both directions w/o bloat or sibilance: try the upper-crust of the Siemens 6922 family(7308/E188CC or CCa's). If the recorded material is warm, they will let it through, but will not add anything of their own. It's hard to exceed their performance(I've tried). They're pricey, but worth every penny if you really love your music. Happy listening!!

Everyone thank you for your suggestions!! I bought a nos B&K 747 from Brent Jessee that I will receive next week. I was looking at a Hickock 6000A but decided the B&K was easier for a beginner, any thoughts or suggestions ?

Samhar-

Let us/me know how it works out. I've been following this thread and am in the same boat.

Best-
