I think this video teaches the construction of a tube the best.

You are quite welcome! I have a couple of more items to post from them but my work browser is FUBAR on formatting so I have to wait until I get home. -HK sends

EDIT:

I can fix under exposed better than over exposed / glare.  Because they are smaller .jpg files they tend to pixelate when manipulated a lot.

Again, these are over amp'd to bring out detail.

 

 


They are better.  I'll try and send the large size files.  I'll take a few more of these Reflectors as well.

Here is a link to a Dropbox folder.  Put the large / original image there.  I'll correct them and name them 'fixed-1.jpg" etc.

If you like them, you can post them.  I didn't want to drag them down without permission.

 

EDIT:

Didn't mean too imply the images were bad, I think I can bring out the getter more.


They should all be in there and a few more.

Makes sense, the data sheets are quite different between the 23 and the 1. Looks like I'll be snarfing up a few of these while the price is low. smily_headphones1.gif
One more twist.... How about the triple mica black plate variant?

I have a feeling this thread can make prices jump.


... I've got a couple pair of CV2493/01 on the way. Kinda funny. The voshkod were just in and the wife was threatening to throw out all my Schiit.... just as I won. Tubes and a divorce coming up. win win. :-)

Well, we  can always dream.

I actually got an answer to your posts from TubeMonger:

 

"Funny, we have been working on one such item for a while with some electrical measurement features. Simple passive unit without electronics should be easy to derive."

 

I know I'd like to see it!biggrin.gif

...and this:

 

"Anyone try 1960s Siemens & Halske PCC88 in Lyr. Here is a photo for reference. Most Siemens PCC88 tubes in the market are late 1970s-early 1980s without splatter shield above the plates. 

 
BTW, Telefunken PCC88 batch should be here in next 10 days. We can bid on this Siemens lot also.

I know I've tried the later S&H PCC88s which weren't bad at all.  I'm curious to see how the Telefunken PCC88s sound...

OK, I've finally made a decision.

 

A/B comparisons are not easy, there's a lot of work involved, and these tubes are really closely matched.

 

But I'm going with the Orange Globes.

 

The bass heft and slam was slightly better in the OGs than in the RTCs, but I found that the difference wasn't nearly as pronounced as I originally thought.  Maybe the RTCs burned in a bit more, maybe it took more critical listening to hear the difference clearly, I'm not sure.

 

The soundstage was better with the RTCs. It was more three dimensional than with the OGs, but that difference was also less pronounced that I originally thought.  In fact, going through this exercise has given me new appreciation of the OGs soundstage! The soundstage of the OGs is not quite as  "intimate" as I had believed.

 

I'd say that the high frequency reproduction was superb with both pairs of tubes,  if I had to decide based solely on the treble, I would still be agonizing on which tube to pick, I don't think I could ever call one really better than the other.

 

What tipped the scales in favor of the OGs was that sweet, sweet midrange.  The midrange of the OGs was fluid and mellifluous, but never bloated or bloomy.  The RTCs had nice midrange also, to be sure.  But the mids on the OGs were just better.

 

I hope I don't have to do this again for a while at least.  I'd much rather just relax and listen to music!

Just a heads up if anyone is interested- Upscale Audio is selling Telefunken E88CC/6922 for $109 each. A great price for an excellent tube

I've got boxes filled with tubes all around...they get used to it...after about 10 years!  It's the boxes filled with cables they really can't stand :-0
