Tube for CAT Mk3

I bought a CAT SL-1 III used, and sent it back to the factory for a phono stage. It had two NOS tubes replacing 6922's, and the factory told me that was a bad idea, that they weren't rated to handle the current the 6922's in that position would get. So I'd check with the factory on where it's SAFE to use other than 6922's. They're very friendly and helpful. Phone number: (716) 359-2700.

Oops, I see that the responder before me warned you already, and more specifically than I could, about voltage ratings. Sorry to be redundant.

Call Kevin Deal at upscale audio.Ask him about NOS Radiotechniques.They are great for CAT's

CAT owners beware... Please note that when using different equivalent as for the 6922 at position V6 and V7, you are in risk of blowing a couple of fets. this has happened more than once in my CAT,[recently MK 3 upgraded] so as i read about a guy who throws in 20 [!] different brands/equivalents and thinks everything is workin'fine....it sure get's my heart rate up. You may do this searchin'and trying just to get a 'sound' but the CAT has a specific design around the V6 V7 6922, and so uses very closely matched Sovtek reflector series. this is recommended by the factory, and for reason. If you are able to get amperex or siemens or whatever NOS thats ok, but you are indeed one in a million lucky guy who still can come up with a pair which are up to spec's for use at V6 V7 DON'T SAY I DIDN'T WARNED YOU... if in doubt call Ken Stevens [CAT] or Kevin Deal from upscale audio. Happy CAT owner for 7 yrs, wouldn't trade it for any other Enjoy. Ron [the netherlands]
