Cary SLP-05 - rectifier tube questions

Hey All,

Several days ago, my 05 began to blow all the fuses (HiFi Tuning tweak ones too.. damn it!) and wouldn't power up. I found out that it was the rectifier tube that was blown and I swapped it out for a local 5AR4 tube that I found at my neighborhood Guitar Center.

Swapped it in and VOILA! Music again!

ONLY... this time, it sounded different - imaging wasn't as clear, there was a "dirty background" to it all, the voices didn't respond the way it used to from my memory when I turned the volume up, the stage was set further back behind speaker plane...

I am using Martin Logan Summits which are ruthlessly revealing of any upstream component.

So I began suspecting that there was a change and it might be because of the crappy rectifier tube that I just swapped in. A search on audiogon and many other forums seemed to validate my opinion and that rectifier tubes DO change the sound! I didn't know that! So I had NO bias going into this...

So now, I'm in search of the perfect 5AR4 rectifier tube.... a lot recommend the Mullards, but are there any other recommendation for tubes that are not so overly pricey?

The Cary 05 uses only 1 5AR4, so in that sense, I'm lucky I won't have to buy a pair...

Help me out, thanks!

Hi Joey,
My 9 months old SLP 05 just started to blow the main fuse and then the high voltage rail fuse..I havent found out why exactly did it do that just yet..I'll call Cary tomorrow..and hopefully it'd be the same issue as yours ..BTW..how does the Miniwatt metal base sound in your unit? I have 4 here but havent tried them with the Cary yet. Your feedback on it would be greatly appreciated!!

I just talked to Cary today..and Gerald suggested to replace the 5AR4 rectifier tube...I did..and all is well again. BTW I replaced the bad one with the Phillips Miniwatt Metal base GZ34 .

Hi Joey,
I bought 4 of them, 2 from TubeDepot and 2 from TubeWorld before they ran out!!!

I used a pair on the Manley 300B Pre (sold recently) and 2 are new.
Well, immediately after i replaced the bad stock tube with the new Miniwatt, I played a few discs (David Sanborn's DVD-A, and Tord Gustavsen's cds), and the difference was pretty audible to my ears and my friend's: bass is tighter , deeper , and especially sax has more bite and breath. Pretty cool tube!!!!
Did you get yours yet??
