Little Dot I+ Tube Rolling - Page 132

post #1966 of 1979

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):

Awesome man! Thanks!

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.

would the Voshkod 6ZH1P-EV be good for MS1i's? 

post #1976 of 1979

I am both lazy and clumzy, so since I don't want my beloved LD1+ to go up in smoke, I would like to roll tubes (I have the stock tubes now), without having to open the unit up to fiddle with the little switches.

 

System no:1 consists, of a Yamaha DVD-S1800 SACD player, a Yamaha YP-D6 TT, with an Audio Technica AT95e cartridge, a vintage Yamaha CA610-II, inegrated amplifier, and the headphones are all Grados (yes I have joined the Dark Side), they are GS/PS/HP1000.

 

System no:2 consists of a Yamaha DVD-S2700 SACD player, a Technics SL1200 MK2 TT, with an Ortofon 2M Black cartridge, and a Yamaha RX-V2200 Dolby Digital/DTS Reciever, and the headphones are the same as system no:1.

 

 

I realise that it's a lot of information, but I figure the more you know about my system the better. So any suggestions would be greatly appreciated.

The Voshkod's are regarded as some of the best all around tubes for the LD1+ and with grado headphones. i've had them for some time now and can attest to their excellency. They've been reviewed a few times now on headfi and are highly praised. They are the final tubes I bought and have been on my LD1+ for years now. I could sit down and compare them to the stock 95's I have but, all I remember is that they did in fact provide an audible upgrade to my music. I can't recommend them enough! :)

post #1978 of 1979

I'm sorry if this has been asked before, but I haven't found the answer yet. I just got my LD +1 and am completely new to tube rolling. I got it with a set of 6HM5 Yugoslavias, the stock 6JIs, and Hytron JHY-6AK5s. I want to make sure I don't break anything, so can someone please let me know if I'm doing this right

 

6JIs and the 6AK5s should use the same jumper setup (J1, J2 uncovered) and the 6HM5 (which is equivalent to an EF95?) should use the same setup as the EF91/92 in the manual (J1, J2 covered), correct?

 

Thanks!
