so now i can relax having at least one problem less :-)

 

by the way, to complement my post, here are two pictures of the nice little machine i used for that:

GermanGuy,

That's a very fine piece of machinery.

Would you consider making a few pin cleaning kits for thread participants to purchase? As although the fibreglass pen works well, it is a laborious process and your method is far more efficient.

The garnet cleaning powder looks good too, though it appears to be sold in 25kg bags, and not even Ian has that many valve pins to clean - well not yet anyway!

Cheers,
Andy.

I wonder if this stuff (garnet powder) would be a good replacement for the sand as it is even finer and would polish the pins at the same time as deoxidizing them?

Just as this amp is the first of its kind your cleaning process is the first of its kind as far as I am aware, I love it!

I can't wait to see your solution for supporting the amp, would you care to share your thoughts on the forum as well as I think they sound as amazing and innovative as this pin cleaning solution!


i was looking for something similar to your garnet powder because i did some research about sandblasting with airbrush equipment. it's a great recommendation.

 

at the moment i think of an autorotating wood disk using some parts of my lego mindstorm robotic kits equipment, you could even write a cleaning program with increasing / decreasing rotation speeds and much more with it!

 

to be honest i have started to look for parts to build feet and/or a cradle for the amp, something similar to the way turntables are decoupled from resonances like two pieces of wood and/or stone with dampers between and spikes as feet, something like this.

to make ten cleaning toolsets now is just a question of two hours, and (please don't think about purchasing, i hope that i am allowed to just send it as a little gift for you, would make me much happier) it will be a pleasure for me to provide you all with a cleaning set consisting of a wood disk and better 3 foam rubber disks.

 

most of the effort will be the packaging and one walk to the local DHL shop, and also this should be absolutely no problem.

 

i propose to wait until i get a feedback from this two mutual lorenz tube sources, eventually combining the packaging of the cleaning sets with tubes if one or both sources have lorenz tubes but not being able to sell directly to you outside germany.

Honestly, the kindness and generosity of spirit by the participants on this thread is outstanding! I think this, the FAD thread and the Terra player thread are the top three threads as an example of community working together on this forum. GG, your generosity is outstanding but at the very least let us pay for shipping as that costs so much!

Your ideas for the support feet are something I am looking at with a great deal of interest.
Here is a video of the way still points addresses isolation.
http://www.stillpoints.us/introvideo.html
i have heard the differences between using these and things like cork or sorbothane and what they chap in the video says is absolutely true, it was like upgrading a component by quite a large margin!

From what I can see the units contain ball bearings and the vibration from the device is transferred into heat and dissipated

I know my very crude and simple experiment in decoupling by using brass rings directly under the amp which then sit directly on the wooden support has increased air around the notes and given a richer full bodied sound compared to using the amp resting on cork
post #651 of 3317

i crossposted the link of my cleaning method in some tube rollings threads, maybe some members would also be interested, but you won't believe, in the schiit lyr tube rolling thread one guy posted, that even one of his socket savers would cost $50 seems he felt disturbed why and how could  such a 'tube profi' tell him how to clean and why at all cleaning tubes ???

I know!

I think there are so many out there that see no point in cleaning the pins. I just found that by trial and error any potential noise, especially the what I call tissue paper scrunching noise just vanishes with clean pins opposed to oxidized pins.

I actually did one set of tubes with de-Oxit as a friend had a can. I much preferred my method and it was a whole lot cheaper, now you have refined it to such a wonderful point to save time and I bet that your method is much better as it is really hard to effectively clean the sides of the pins with my method.
post #653 of 3317

i also had the problem before using my tool - cleaning the sides of the pins.

 

i checked the dhl parcel price - it's nearly usd $50 international shipping - now i know how they earn their money.

 

but the 'deutsche post' is much cheaper, you can buy a ready to use envelope for international shipping including address label, customs declaration and shipping cost (up to 500 grams) for just euro 4.90 so also this is really no problem.

The generosity of spirit and wonderfully informative nature of posts in this thread, is testament to what can be achieved when folks of a similar ilk commune without prejudice, and concentrate on maximising the musical enjoyment from equipment.

Having been an early champion of the Tera Player (I purchased the second commercially available unit) it was quite unpleasant to be vilified online for publically supporting such a niche and expensive DAP. However, quality in whatever form always transcends mediocrity, so now the Tera Player is acknowledged as being a fine sounding player.

My friends this thread is fortunate to have an eclectic mix of erudite valve collectors, ingenious pin cleaning innovators and a genuinely interested mix of readers, all of whom appreciate the general discussion of Analog Paper^2 amplifiers.

BRAVO to you all!

Cheers,
Andy.

GermanGuy,

Outstanding idea and construction. If you do decide to sell these, please count me in to purchase one or two of them, too.

GermanGuy,

 

You should at least barter a bit.  Tubes for tools, and the sort...

post #657 of 3317

Just woke up about couple hours ago.

Had a routine morning stuffs.

Opened up my laptop, directed to this wonderful thread with a sip of breakfast coffee.

And.. Dang...! 

GermanGuy, you're superb...!!!

It really makes my morning.

 

I always write about how excellent the genuine support that have been given by any participants in this thread.

And yet.. There's always another pleasant surprise we got everyday.

I salute you guys... beerchug.gif

I would like to share some of my discussion with Shikada San regarding few issues.

Italic blue were his feedback.

 

- Power switch.

  I think you say independent power switch.
  If so, It is on your TU-05.
  (Jack sense switch is smart design, but a little fragile. so, I decided to mount an independent power switch for overseas.)

  With that, I assume that the separate switch is a default option now.  

 

 

- Related to Anakchan's post about lower than 30Hz on bass region.

  Yes, 
  Although depends on the affinity of the headphone, TU-05 is able to output 20 Hz.
  In the my measurement, it means can be guaranteed ~30Hz at the severe criteria (± 3dB). The below 30Hz, follow decreases, the volume becomes small.

  Well, honestly I do not really get it.

  I love to have the 20Hz region, but at the same time I don't want it to affect the overall sound quality.

  With the above reply, does it mean it will affect the volume?

 

 

- Gold color.

  Oh, I am thinking just!!
  TU-05g (gold)
  I might make out as limited model.
  If you need it color,  please let me know immediately. Before your parts are painted.

  Ian, it seems Shikada san has the same idea as you. biggrin.gif

  I replied to him that if the golden color is similar or at least close to those Luxman color, then I would love to have it.

  I need to ask this, because sometimes the golden color can become too obvious, kind like a bling-bling stuffs which I would try to avoid.

  I'm still awaiting for his feedback about this.

  Btw, on his reply, he mentioned the additional cost for the gold color, but I prefer not to put it here.

Very interesting Boringer. I guess the trade off for going lower is volume.

I know Shikada San has explained to me before his English is not great which is a reason why he does not like to post here as he feels he may not be clear enough, I said we can work round things like that.

What sort of music do you listen to in the main? I must say that the stock tubes though sound really nice do lack bottom end. I found all of the NOS tubes to better them in that respect Mullards and now these Mil-Spec Sylvania's being the best at going deep but still keeping things tight.

Though not a bass head I do love good quality bass for its ability to underpin say an orchestra and make it feel more real and I feel the NOS tubes I have purchased satisfy my bass needs perfectly, but as I say, I am not a deep thumping bass person and I think SET don't do that well anyway.

I think personally I would not upset the balance of this amp other than fine tuning the tubes.

As to the gold colour, wow, that would be wonderful. When I think Luxman gold I think champagne gold, similar also to the old Marantz colour.

Here is an image of what I have in mind, if he can get it to that colour I personally think it would look amazing.. Wonder if he can anodize the volume knob as well, it would have to otherwise it would look wrong. It is made of metal so I can't see it would be an issue. In fact imagine the knob slightly darker as in this image!



Or the new exquisite Robert Koda stuff!

Thanks Ian.

In that case I might leave the lower region to remain as it is.

I listen to slow music, such as jazz and vocal oriented musics. 

Same as you, I appreciate the quality rather than quantity on the bass.

Well, anyhow we should have another amp for that purpose, shouldn't we...?  biggrin.gif

 

And I also agree with you for the champagne gold.

I send the following pictures to Shikada San to make sure he can make it similar or at least close to that.

Agree with you again on this.
