Sounding good as well.

6H30 is "Amazing" sound for the price.

I would have to do some tube swapping to get the essence of 6h30 supertube but from my recollection - this tube has greater inner detail, air, soundstaging and body.(compared to stock JJ)
As you can see, swapping tubes or voltage is a matter of seconds and can be done on the fly with access to both, tube & voltage selector.

Very happy customer indeed.

Here is a pic of the inside of a Gary-built buffer. I think there is plenty of room for a larger tube. Hope this helps.

I noticed you don't have the "bypass" caps yet.
"bypass" caps will bring the buffer up to another level

Should be fine. In vertical orientation, tube just wouldn't fit. We are talking about 1/8" or so but nevertheless, you wouldn't want to take that chance.

One thing at a time...

On my shopping list
1. 6h30 tube
2. Pavane 12xxx tube
3. Bypass caps

^^^^^
Get the "bypass" caps, you may not need the Pavane.

^^^^^
So your advice is to switch the order and get the bypass caps first? Even before the 6h30?

^^^^^
6H30 and "bypass" caps are almost same price.
Either way is good.
You will hear the difference when you add each one.

Trung,

What is the bypass cap I should be getting? Sonicap platinum? What value? They seem pricey.

TrungT · « **Reply #652 on:** 11 Dec 2010, 05:43 am »

Sonicap and Gary can hook you up.

Get bypass first and wait a little then start changing tubes.

If you are buying a new assembled kit for a 6H30 tube would it already be cut out, or is his just in your case?

That's just my own take on Dodd buffer case.
- I like exposed tubes
- much easier to swap tubes and voltage
- IMO looks cool
- I also inserted dark wood inlays in all control
knobs - imput, power/mute,volume. Makes them easier to read from across the room. It also helps in avoiding mistakes like leaving the unit ON or in Mute position and possibly draining the battery dry.

Gary can rearrange things inside the case to accommodate tubes such as 6H30.

Anyone have any pics of the single tube conversion that they did?

Just follow the diagram:

I can snap some picture if needed.
Just give me a buzz.

What differences do you notice with the platinum bipass caps? I mean a real, meaningful description, not just high emotion comments ("must have", "blow you away", "you won't regret it", etc.)
Not all upgrades work for everyone. I would be willing to pay for something that gave more ease to the presentation, opened up the soundstage, more 3d depth, or such.
There's usually some noticeable degree of electronic tension to these machines we use, anything that lessons that is to me an upgrade.
I'm deciding whether to include the platinums with my order.
Thanks, Don

Great job answering your own question.

what a coincidence...

Just wondering if anyone can describe any noticeable sonic change when adding them to the buffer.
