Wow, I had no idea, thanks!
It's looking more & more that the amp is a REALLY good deal ($89.99 if 5 more people besides me order it), but the tubes are not so hot.

Yeah, $89 seems like a very good price. This is a very capable and fun amp.

As for tubes there's a lot of things at play, such as personal preference, headphones, music, op amps etc

You'll probably end up with more than one pair of tubes eventually (or you'd rather spend more on tubes than on the amp eventually :wink:) but there's a lot of information in this thread so I'd start with one of the more popular warmer sounding ones for the HE400i and take it from there.

That's the fun of tube amps, there is no set rule for which is better. I believe many said 6HM5 are great with the grados.

Any one using v5i havin an issue of missing one of the channel after a long usage? It happened twice to me on b5i and nothing else

I have two V5i's that aren't good....after playing for a while in the LD 1+ they start distorting, like within 15 minutes to an hour....they wouldn't even work at all in a CMOY type amp I built that has run just about every dual opamp I can get my hands on....I got a second set of the V5i's from a buddy and they work fine in both applications....I'm trying to figure a way to get the bad ones back to Australia cheaply as most shipping options are darn near what the opamps are worth...

Looks correct to me for EF92. Jumpers on the two sets of pins circled red and all the sets circled blue to the left.

Remove the jumpers in the red circles for EF95.

Sorry thought the pins in red circles where covered with jumpers.

EF95 (stock, = 6J1P)
Blue circle = 3 jumpers left
Red circles = uncovered

EF92
Blue circle = 3 jumpers left
Red circles = Covered

408A
Blue circle = 3 jumpers right
Red circles = uncovered

The more expensive pair are matched to within 2%, while the cheaper pair are matched to within 5 - 10%. Since tightly matched pairs offer no advantage in the LD, the cheaper pair is the best buy.
