Found the 5x20 fuse in the STR-1002 IEC. Looks like it's ceramic not clear glass so I can't tell if it's blown. Anyone know the amp value on the fuse, I can't read it.

Thanks Tony. Did he specify fast or slow blow?

HK, Don't know if you have one around, but multi testers tend to have a continuity setting with a sound setting. In the case of a fuse, we would measure between the ends, and if there is continuity, it is not broken and you hear a sound. And if it is blown, no sound. I find them handy for a lot of things, used similarly for verifying the right wiring of power cable or IC ends, or checking house voltage, DC voltage, cap and resistor values, etc.

If you don't have one, I saw a cheapy on amazon with lots of happy ratings for like $14, and these days you can get some pretty nice ones for not a lot more... And who knows, I did not read up on it, but this one may be pretty accurate.

Here is a response Al sent me for fuse replacement for an STR1002:
Thanks for asking, the fuse in there is 1.25A 20mm slow blow, you can use 1A~1.5A slow blow if you cannot find 1.25A, or 1.5 fast blow.

Thanks all. Al responded and said a 1.25A or 2A slow blow fuse would work. Suggested I try a 2A given the larger power supply. Ordered both from Amazon and should be able get it back up and running on Monday.

That is good news. I've been #mercurycurious but have held off because of our cats. But the various issues that folks had with the mercury rectifiers has dampened my enthusiasm by a lot.

You are not alone, hence #mercurycurious. But, my Elrog 845s do sound better than my (inexpensive) Chinese triodes. I (infamously) said my system sounded so good it was hard to imagine the STR making it better, so I'll never say never, but today I'm happy listening to music and I'm not worrying about tubes.

Yes, I found the same thing. But for me, in my non-Decware preamp, running 5V rectifiers (and/or 300B tubes) in the STR was a relatively small improvement vs. the 10V transmitting triodes that were a blow-me-away improvement.

The Linlai 845 DG's are back in my STR-1002. The music just sounds exquisite in my system configuration. Picking up a used Snake River Audio Signature Series power cord to see if I can extract even more good mojo from this sterling performer.

Tony, you answered my questions. What was being powered by the STR.

Tony running the STR into the Sarah and CAJames STR into CSP, seems like my hypothesis is still holding.

It might be good for us when discussing which tubes we like to mention what component we are powering with the STR.

I have been remiss in not sharing my listening observations of the STR-1002 (Super Tube Rectifier) which has replaced the Psvane Treasure 274B rectifier tube in my CSP3 preamp. I have only listened to the STR with the stock Linlai 805 and a pair of Linlai 845 DG tunes. My system information can be found at the bottom of this post. My listening area is a modest, well treated 15.5'x13.5'x7.5' basement room with my ZMA and Caintick Audio Magnum Lii F15's front and center. Is it about 11' from the speakers.

While I could go into a great deal of detail regarding the improvement in sound quality resulting from the STR-1002, I'll great straight to the point: I am now enjoying the most satisfying, immersive music experience EVER!  The music evokes an emotional response and is so REAL!  You just get sucked into the performance, it's so seductive. It's a reach out and touch the performers with my single driver open baffles. I have difficulty wrapping my mind around the change, particularly with the Linlai 845DG tubes fully settled in now

I'd get into the technical aspects of sound quality improvement, but the words will simply fail to do justice to what I'm hearing. As previously noted it's just TOTALLY EARGASMIC!

90% of my listening has been Room/Qobuz streamed music via my MWI modified CXN V2 streamer/DAC. I did spin Dire Straits Love Over Gold (MoFi 45 RPM) last week. The bass response from my frequency limited Lii Audio F15's was jaw dropping and I'm no bass head.

So Al the Mad Scientist has created something really special with his Special Tube Rectifier STR-1002, IMHO..You'll have to pry it from my cold, dead hands when I pass to the other realm.
