+1 on Langrex. Plus, they know how to pack tubes properly for shipping!

So I'm new to the tube amp business, so I'm not sure what would be good or not tube wise.  I have the opportunity to buy a pair of 1945 Western electric 6AK5 tubes, and im not sure it would be worth it would they be decent? I would appreciate any and all help.


Thanks

Some opinions after a long use of it?

When I got my Little Dot 1+ last year, wasn't happy with the sound, so ordered the Voshkod EF95 tubes and a Burr Brown OPA2107 opamp.  These were way too bright sounding with my Grado SR325i's.  Been doing some reading on this thread over the last few weeks and today received some Mullard EF91 M8083 blue glass tubes.
 
What a difference.  Much nicer to listen to, less bright, bass appears fuller while still retaining clarity.  Currently spinning some vinyl...

Nice, those are the tubes I'm looking at. Where'd you get them from?

 

[richie60]

Got them from a seller on ebay.  He had the last two in stock!

Here is a link to a pair that I saw earlier today.

 Nice sounding tubes, some of my favorites, and a lot cheaper than above link, just might take a few weeks to get to you.

OK - I've dropped on an LD I+ - I've been reading and watching some reviews and a common complaint is that the manual is not easy to read.
 
My main concern is that I need to alter jumpers for the 5654 valves that I've already got. Can anyone offer any advice please? Are there clearer instructions anywhere?
 
Also, I've heard about the OpAmp replacements, and have tried to follow a number of pages, but I can't handle all 182 pages, so if someone can pass on some advice on OpAmp's, I'd be grateful.
 
Listening goes all through, vocal, brass, rock, headphones I'm using these days are mostly Sen 600 and Beyer 990 Pro.

 

[richie60]

I don't think you'll need to change jumpers for the 5654 tubes as the amp ships with it set to use EF95 by default. The manual is basic but it is easy to understand if you read it carefully. Everything was labelled clearly on the PCB.

 

[gulakpi]

Yes!  You don't even need the manual as the PCB is clearly labelled.  
Don't forget to repeat the process for both (left and right) channels if you ever need to change the jumpers!
If you will be replacing the EF95 stock tubes with 5654, no need to touch the jumpers! Enjoy!

It depends on which version you bought.
 
If it's the 6J1 version then no worry.
 
If it's the EF92 (6cq6) or WE408A then yes, you'd have to change the jumper. Press Ctrl + F when you're on the reader and find the word "jumper", that way you woundn't have to go through 182 pages.
 
On opamp, there's a slot on your Little Dot after you have removed the underboard (it's really really easy). 
 
Actually, just remove the underboard of your I+ (by removing 4 screws, 2 on the forward panel, 2 on the back panel) and take a picture of the PCB. It'll be very easy to give you instructions from there.

Hit page #181 and I've got a snippet of a review I'm writing on the I+

I have not tried those but I think they should be OK, considering it's WE and all.

 

[msknight]

Thanks folks for the advice so far.
 
I've been reading and have my Philips and Telefunken tubes (ordered some more to replace the ones that got blasted with the Little Bear problems) and also some Mullard EF91/6064... so I'm assuming that I don't need to change the jumpers for those, either.
 
What are my options for the OpAmp please? I'm getting thoroughly lost with the choices. Preference is vocal and brass. Target phones are Senn 600 and DT 990 Pro

 

[richie60]

You may like it stock. The good choices seem to be the MUSES01/02 8820 8920, OPA2107. Just pick one and try it just like tubes, you'll settle on one you like the sound of.
