Little Dot Tube Amps: Vacuum Tube Rolling Guide

I removed the Rings on my I+, it's not that hard took me about 15 minutes or so.
It's look better that way in my opinion, with the adapters it looks a little weird and too tall.

Hi NiMo7, can I ask you in general how do you remove the ring on your LD I+? and what sort of tools would I need to remove them?

  Hi NiMo7, can I ask you in general how do you remove the ring on your LD I+? and what sort of tools would I need to remove them?

It's pretty simple, I learned how to do it while doing it.. You will only need phillips screwdriver.
Each ring is held by two screws underneath it. To reach those screws you need to remove the board by unscrewing all the screws that holding it to the top cover. After you remove the rings just screw back the board and you are done.
Do all of this with attention not to tear the wires that connect the board the front and back of the amplifier.
 
Hope you could understand from my bad english..

Hey all,
 
First of all, thank you all for putting so much effort into this thread while being so noob-friendly at the same time. The amount of information is overwhelming, as I'm only 50 pages in. However, it does seem like the consensus is that 6MH5>M8100=M8161=6ZH1P-EV are the more wallet-friendly options for the MK III which I own. I don't plan on rolling too many tubes, but these are definitely the ones that are worth a try, right? Is there a preferred brand for the 6MH5's? Lastly, what are the best power tubes, price-performance-wise, for the MK III?
 
Best regards,
Wayne

Yugoslavian EI-6hm5 tall bottle are considered best driver tubes and 6N6P-IR for power.There are better options but use adapters,socket savers,PS,etc.

These are the adapters that I should use, right? But why is it from 6cg7 to 6sn7? I thought the mk3 uses 6ak5.

And what will be a good price for sylvania 6sn7's? Does gta/gtb matter? They seem a bit pricey on eBay. From what I read, I assume it is okay to use unmatched power tubes, and all the 6sn7's work pretty well. 
 
Man, I feel like I'm putting together a puzzle, except I don't even know what the pieces look like yet. I have the mk3 on the way, voskhod's on the way, rtc 5654rt's on the way (hopefully they are actually re-branded m8100s), 6hm5's on the way, and most importantly, the new headphones on the way. Now to add to the list, the adapters and power tubes. I can't wait to get this over with, this is too intense...

If you are hoping to use 6SN7 as power tubes, then yes, those adapters will work fine.
 
A nice pair of Sylvania 6SN7GT or 6SN7GTA (I would not encourage you to get 6SN7GTB) can often be purchased for around $50. For example:

Hi f95xxx,
 
The bigger tubes in the back of the amp are power tubes (the ones in the front driver tubes). The back ones use sockets with 9 pins, the front ones with 7 pins.
 
The LD MKIII uses 6AK5 type tubes with seven pins as driver tubes, but the 6SN7 should be used for power tubes.
 
The 6SN7 tubes use a different base with 8 pins called an octal base. The purpose of the adapter is to allow octal 8 pin tubes to work in the 9 pin socket. It is very simple - literally plug and play.
 
Gibosi is our resident tube expert and you cannot go wrong with any of his recommendations.

+1 on the recommendations of gibosi. Although he is a danger to your wallet too, my LD +1 has sounded sublime since I invested in the muses02 opamp along with a pair of 6HM5s that he recommended, has taken my listening pleasure to a whole new level, and my AKG K550s have never sounded so sweet.

  Thanks for the input. It might take a while because of all the international shipping, but I will let you guys know how it goes.

Can't wait!
