Little Dot I+ Tube Rolling - Page 132

post #1966 of 1974

Search ebay (worldwide) for "6HM5 Yugoslavia"; The vendor is www-tubes.rs located in Serbia.

 

Here is a listing for 4 tubes for $24.50 (or maybe less with the "Make Offer" option):

I used my Ld 1+ with QXX1 nice pair.

Also have the LD 1+ with MUSES 02 op amp and a pair of tall-bottle EI 6HM5 on Q701. Sounds great to me!

Ahhh, there it is! Up until now I have not been happy with my Little Dot. Started with 6J1 then GE 5654. I swapped the op-amp to a Burr-Brown opa2107. Still no good. Recently I found a matched pair of new old stock Western Electric WE408A (mfg date 3/54). My amp finally sounds the way I expected it to. biggrin.gif

I recently picked up my new Little Dot I from Amazon. I'm pairing it with Grado SR125's. An Amazon reviewer recommended rolling in Voshkod 6ZH1P tubes, which I did. I also purchased an OPA627. 

 

I'm new to this, so I was hoping to get some advice. First, is this a good combo for rock music? Second, do I need to change the jumpers for the new tubes? And third, can someone point me to a good post or article on replacing the opamp? I've never done it before.  Thanks in advance, guys.

The Voskhod 6ZH1P is the Russian version of the 6AK5 / EF95, so if your amp is set up to use EF95, you don't have to change jumpers.

 

Swapping out op amps is very easy. The only thing you have to worry about is aligning the notch or mark on the op-amp with the notch on the socket. This post might be helpful:

Thanks for the reply. Probably a dumb question, but is EF95 the default for the Little Dot I? I have changed anything, so do I need to?

 

And that's for hte link, that's exactly what I was looking for.

Yes EF95 is the default as the base price of the amp includes the Chinese 6J1 (EF95) tubes installed. But if you purchased the amp with upgraded tubes, then it would have come configured to run either EF92 or 408A, depending on which of these upgrades you purchased.
