Little Dot I+ Tube Rolling - Page 100

post #1486 of 2046

Can anybody point me to the best place to purchase a couple opamps.

 

I am interested in the following

 

OPA2107

 

JRC4556

 

If anybody here has them for sale that would be great also.

Ebay - you could probably get both of those for like 10 bucks shippied

I have never tried it, but I think that is what is used in the Grado RA1, if I am not mistaken, and I very well could be.

 

I was just not sure if  e-bay would be full of fake chips....RAZRr1275

Mouser & Digi-Key.  The JRC4556 might be a bit hard to find (used on some older Creative X-Fi cards I believe).  OPA2134 might serve as a replacement iirc.

 

Is this for your LDI+?

 

The LT1364 is another popular choice.

 

Cheers!

The LD1+ is coming with 3 sets of tubes....Mullard EF91 matched pair......4080A Sylvania gold matched pair....Mullard EF92 matched pair

 

It also will have 2 opamps......I will get 2 of these 3 listed....I just don't remember which ones for sure.

LME49720

LT1364

BB OPA2134

Great sets whirlwind. IIRC, you are also on the Grado thread. The Grados love this little amp.

Congratz!

Only tested one of the ones you mentioned, but I tested several opamps other than the usual ones here:

I just ordered two free samples of the 2107 from TI, and I picked up a matched pair of Voshkod 6J1P-EV tubes, and I'm still waiting on delivery of the Little Dot I+... I'm getting started even before it arrives. :)
