I usually let the solution work for a few minutes before wiping off. However, my timing is completely arbitrary; I don't recall reading a specific min / max duration for initial application other than to repeat until no further oxidation comes off.

Thanks for the reply.  Yeah, I've never seen timing published.  That's about the same I use with the Gold. I ended up ordering some 99% isopropyl alcohol for cleaning before using the DeoxIT Gold.

That Furman looks to be a good deal.  Something else for my wish list.  Makes me wonder if the UPS I've got my Schiit plugged into does any conditioning, nominal though it may be.

 

Enjoy your new tubes (very nice!) and post some thoughts when you've burned 'em in and had a proper listen.

 

 

I think on the 100% nail brush bottle it says to let it sit for 24 hrs. if necessary.  But I don't think you should use it on gold pins.

Interesting.  I wonder why they made the 25% solution for the kit.  The Gold Series does have some deoxidizing properties, but it's very slight by comparison.  I suppose because it does deoxidize, that's why any excess should be wiped off.  Gold-plated pins shouldn't oxidize that much anyway.  The problem with gold plating is that it wears down eventually, if you're plugging/unplugging/plugging... a lot.  Too bad CAIG doesn't have better info re: use and best practices.

It could be an issue with the HP cable plug. I've had good luck with the Richard Gray RGPC 400 and 400 pro power conditioners.

Just got a shipment of 6n23p bought on ebay from Romania. The tubes were different then pictured. 2 of the 8 failed testing - 1 very badly! Buyer beware on these. It may hard getting more from the Ukraine for a while.

A lot of people are trying it on their K/Q 701s.  I think it can be done on the 702s, but you can check that thread.  It will boost the bass.  If it's too much, you can also slide some foam over the port which can make for a happy middle ground (that's what I ended up doing with my Q701s).  Made them much more fun, esp. when rolling tubes.

 

Thanks! Just checked it out and looks tempting, for sure. Bookmarked for later, but I'll give more time on the 702s and see how the new tubes burn in over the next couple weeks before I go digging around.

I bet they made it 25% for gold pins.  Maybe.  I still don't know if you can use that stuff on gold pins.  (so don't use it on gold pins.)  I have read everything I can re the caig deoxit instructions, and have gleaned very little as to actual use.  I still have questions.  Like how much gold deoxit to use on the pins before inserting them into the socket on the amp?  Stuff like that.  I looked on their website, and read their information there, and read the instructions on the back of the tube kit box, and all the instructions on the bottles.  Like I said, I still have questions.

Just a heads-up. There is a tube dac for sale on Audiogon. The Xindak Audio DAC-5. I have one and it's really good, for the money crazy good. It takes 1 6922 tube, or can be run from opamp solid state outputs. I love the tube outputs. It's for sale for $280, new they go for $750. I'm not the seller, but it looks like they have some long term feedback. For those who would like the option of a tubed dac or solid state this gives you both.

Maybe, but then the 5% should be fine, too.  I hear ya re: trying to glean info from CAIG and general googling.  Almost fruitless.  I emailed them a few questions.  Hopefully they'll reply this week.  If so, and if useful, I'll post here.  The tube kit instructions say to use D-Series, then Gold, but they don't talk about D-Series on gold-plated pins, so yeah, I skip that (my tubes with gold pins look pretty good).  Hopefully the Gold with its deoxidizing properties gets rid of any that may be present.  I'm not wiping hard, but I've never seen oxidation come off on the cloth, just the gold colored excess liquid.

 

re: Gold on the pins, I don't think it takes much.  I usually soak the brush, wipe off excess inside the bottle, brush it on, then repeat in the reverse direction around the pins.  That seems to get a fairly even coat.  Then I let sit, use a swab (foam is best) and lint free cloth to remove excess from the pins.  If you want to lube up/coat the sockets, I think you'd be fine with the amount my method delivers, but don't wait, just insert and remove, maybe two or three times?  Sorry, not sure about that.  I just use the very thin brush for the kit.  Personally, if I were going to use tubes to lube the sockets, I'd use the stock tubes, or others I cared less about.

You could be right.   The T5p have terrible plugs.  I still don't know why the plug should act up only with certain tubes.  I will try another low impedance can with the noisy tubes to see if I still get static.  If I don't, then it is an issue with the T5p plug...with only certain tubes.  :blink:

I have a good collection that all sound good with my HE-500s.  I've been running my 1966 RTC E188CCs (Heerlen factory, not France) the past week or so, and they sound great with my HE-500s and Q701s.  But so do my Siemens CCas (1969ish).  I also like my Amperex 1961 Bugle Boy Straight Man pair, and 1967 Orange Globes.  The E188CCs and CCas are the best, though.

 

So, your YMMV.

 

What cans are you using with the Lyr?

 

Primary is LCD-3, secondary is HD700

 

I'm looking for as much clean signal as possible but still with tube sound, so far I broke in stock form, it's good, but I want to try something better. I do understand that tube amplifiers are not going to sound perfect, but close(r) to perfect is good too. Definitely enjoying the added power through the LCD-3, since my amp was primarily the STX card, I no longer feel there's not enough juice for certain tracks.

For "clean" with the LCDs, maybe some Siemens or Telefunken E88CCs.  Not cheap, though.  Hopefully some LCD owners will chime in.

What about Genalex are these good? And Sylvania?

 

I'll look into the two you said.

I've got some Sylvania D getter 6922s (AKA, E88CCs) coming in, so can't say yet.  No experience with the Genalex.
