Yes, mine did go away with different tubes. But then it reappeared. Almost like the amp was slowly killing the tubes! Silly I know ...

Haha I went to work at 11:30 on Saturday to hook it up to my PC. I didn't leave until 2:30, and all I was doing was sitting in an empty office listening to music. Again, silly I know ...

News to me...

It's been about one year so far. Yes, my Little dot II+ does arch but when I don't have the headphones plugged in, the arching is minimal or none.

That said, i still love this product despite the flaw. My question is: How was David able to sell this amp at a low price when he used Mullard tubes as the stock tubes? Aren't Mullard tubes famous thus on the expensive side?

Also, the Mullard tubes says "Made in Great Brittain". Does this mean that these are new old stock tubes?

The regular Mullard EF92 tubes are actually quite cheap at about a buck each. It's when you get into the higher quality CV131 and M8161 variants that cost goes up. For instance, the M8161 is usually listed for $30 to $40 a pair, I think the upgraded tubes does make a meaningful improvement in both bottom end control and treble extension, if you enjoy the LDII+ sound then I think it's worthwhile to check out the upgrade tubes (besides, why own a tube amp and not experience the joy of tube rolling? ).

I've just bought the LD II+ from a fellow head-fi guy jetstream and it sounds great in my budget setup. Anyone else still using a LD II+ amplifier?

Just to let LD II+ owners know, I bought 4LS1 tubes from an ebay seller in Bulgaria and they work much better than the stock tubes. They take Paypal and it wasn't any kind of hassle like the other seller who was mentioned. The seller is orpheus_2005 and they seem to have a stock of them.

I had arcing problems with my amp, and it hummed very loudly when turned down to low volumes. With the new tubes that is all gone.

Thanks to everyone on this thread for all the great info!
