Hello, again!
 
Can somebody (who has experience with the Voskhod 6ZH1P-EV) recommend alternative tubes with more musicality? Details, bass etc. is amazing, but the "foot-tapping" quality seems to be missing. I have the stock op-amp so perhaps that's part of the problem. Please advice. By the way - I'm using Grado.

There are better op amps....  I like the LME49990 as it is very neutral. However, one of my colleagues, who also uses Grado, prefers the OPA627AP, which is a tad bit warmer.
 
 
- RCA 6DT6  Set your LD for EF92 tubes.
 
- GE (Made in Gt Britain by Mullard) or Ei (Made in Yugoslavia) 6HM5 (also listed as 6HA5 and EC900). Set your LD for EF95 tubes. Avoid the small squat tubes that look like 6AK5. Look for the taller tubes.

Sylvania also made 6HM5s, but I haven't tried them....
 
Happy tube rolling!

Thanks gibosi! A thorough answer and very much appreciated. There sure are some helpful guys on this thread.

Just a few follow up questions - do the above mentioned tubes need some kind of strapping between the pins, and is it a reason for concern that some of the tubes draw a bit more heater current from the transformer than the stock 6J1?

These tubes do not require any strapping. And heater current is not a problem. The EF91 draws .3 amps, and considering that Little Dot recommends that tube, the 6DT6 also at .3 amps is within spec. In fact, the 6DT6 actually runs quite a bit cooler than the EF91. Further, I have personally run a number of .45 amp tubes with no problems whatsoever.

Great! Tubes and op-amp based on your recommendations are already ordered. I have no time to waste on unmusical hifi.

Both great opamps! (I prefer the OPA627AP but use both dependent on tube and mood)
 
I'm a huge 6DT6 advocate lol My personal favorites being the RCS black plate and Sylvania grey plate (make sure both are smooth plates not the ribbed) The RCA's are good for a warmer sound, the Sylvania's are more dynamic and closer to neutral.

Hi to all,I have just received my ld1+ with stock tubes 6J1 i have also ordered a matched pair of Philips 5654 E95F. my problem is i am totaly new to this tube rolling well to be honest i know nothing at all about tubes. So after ordering & paying for the tubes i noticed they are E95F not EF95 does this make a differance? Everything i have read has said that not only do the 5654 tubes suit my LD1+ i also don't need to change any jump settings from 6J1 ? please help a keen newbee...

Hey guys, it's my birthday soon and I will be getting the little dot amp and hopefully will be swapping tubes and opamps in the future, but as i'm pretty new to the whole tube thing i'm just browsing at options on here.
 
I read somewhere about Sylvania tubes being epic tubes, and when I saw someone mention the Sylvania Grey Plate tube I thought I would google it... $125?!?!  Are they worth the money?  Are the Sylvania tubes in general 'good' tubes?  I like things that I buy to be a quality product and have a bit of prestige to them... would something like that be a good purchase or not?

 

[kvtaco17]

  what cans are you guys using your LD1+ with?

SR80i, PS500, Magnum V5, AD2000x, HD800 (works alright, you could a little more juice lol)

Good tubes for the LD I + should run you $20/pair tops and usually a lot less than that.  Never buy tubes that are more expensive than the amp...
