Yup, we're in violent agreement re: the Minwax combo stuff -- also learned that the hard way. The stain (color) first, followed by the flat lacquer spray can afterwards -- this explains why your finish turned out as it did. Again, thanks for sharing -- I've filed your wood-finishing recipe...

That last photo = understated, very tasteful looking. (!) I've got the original wood case for my old PL 2000 preamp, and even though it's still in near-new condition, it doesn't have the same curb appeal of yours. Your finish is perfect, not too shiny, very rich looking. Nice! 3D EDIT --...

Check this out -- curiosity piqued, I dug a little deeper and actually found (from back in the heyday of vacuum tubes) a scientific study where they quantified the microphonics of the different components inside the vacuum tube vs frequency: Given the high-frequency ringing we just heard in...

krellmk, I enjoy attending audio shows almost as much as I enjoy live music. The former because I can never predict what I will hear from man or machine, and the latter because, well, for reasons that I will never understand completely, music just makes my mind go happy. :0) In this video...

Lee, my pleasure. I'm way behind in my personal ratio of what I've gleaned from this forum vs what I've contributed. If you could only see all the notes I've taken while reading other member's best practices. (Like vince666 disassembling the switches in order to get them working as new 40+...

derek92994, Great effort & super photos documenting your 10-hour thrash on that phono preamp -- feel like I'm looking right over your shoulder despite being halfway around the world! Reading your post I was reminded of a favorite YouTube video where the Aussies did an impromptu demo of what...

Hi vince666, I'm in the process of attempting to transition a bunch of equipment from a couple of decades of cold storage to daily use as my main system, so I was also reading what Grapplesaw & others were saying about forming/reforming capacitors. This evening I read your restoration thread...

Hi Derek92994, Even though my primary focus at the moment is assembling/re-capping/debugging my personal electronics lab, I made a recent TT purchase that is stoking the fires to ensure that at some point down the road I have the best preamp I can brew up. I still firmly believe that...

Got it! Found a place where you could see them side by side. The 4000 S2 is a very attractive piece! Myself, I have my original 2000 (Series I) preamp, which I will restore/make as quiet as possible. Along the way, I also picked up a clean, affordable, used 3000 preamp, and no doubt this will...

Spence, You have a 4000? If so, you have something in common with The Shat -- I'm old enough to have watched Star Trek from the beginning. (Only in 2nd grade when it started, but that was destination TV for yours truly. :0) Same guy that recently flew into space for the briefest of visits...

Amen. You are so right about this. Not with normal people...but definitely when it comes to dedicated audio guys! And Top Gun would definitely flip your bits in that situation -- great story!

J!m, You wrote that as if you had worked shoulder-to-shoulder with me on all those old-block ANG F-16s. One of the Air Guard mottos back then that actually stuck in my head was simply, "Ready, Relevant, & Reliable". (And a hard-flown 20+ year old military fighter crammed full of Avionics is...

Glen, The other evening I started this conversation with NavLinear. I'm going to PM him this photo and ask for 3+ amplifiers worth! Again, thanks for the 'tested-good' solutions!!! 3D

Ah, I remember those numbers -- eutectic solder! Alright! Good enough for you = good enough for me! Thanks for sharing! 3D

Q: Why share the above here in the 3D rabbit hole? A: The D500 wiring harness *is* a bit intimidating...but with any luck my wiring harness mojo is still in there somewhere...like riding a bike. :0) BTW, I am girding for battle - just trying to decide which Hakko desoldering station to get +...

And here's the proof that a picture is worth a 1000 words -- without further ado: The back story. Back in the mid-90's a bunch of us car enthusiast types started going to either the Spring or Fall Carlisle car shows. Word-of-mouth had it that the show covered ~70 acres down in Pennsylvania...

A couple of days ago I was reading Grapplesaw's latest D500 build, and decided to share how my D500 looked like inside, given it's 'as routed, as built' wiring harness. Today I was discussing some troubleshooting tips, and between those 2 conversations I was reminded of a wiring harness in a 20...

Spence, "uV" = microvolts = millionths of a volt. Shhhhhhhhhhhhhhh -- seriously quiet! And the distortion numbers are way good. Quoting my inner audiophile: "There ain't no flies on that amp." :0) **** You were right -- Glen has raised the bar really high. For me? It's a great problem...

AngrySailor, that's good news. The photo I posted I cropped directly from Carl182's 'exploded 400' amplifier picture (6th one down) -- so it sounds like Carl will be able to dial that in? (I'm off to make a big bowl of popcorn & await his yay/nay report. :0) 3D

Hey Carl182, Check this out -- here's a web page where they are discussing different ways to zeroize a meter, and at the bottom of the page they showed a meter where there was no adjustment on the front (due to physical inaccessibility) ...so they put the zeroize adjustment on the back of the...
