I bought from her over the other DV sellers because of the many recommendations here about her customer service.
She is very trustworthy. |
ya...i ordered my DV332 from jasmine as well...and have a nice chat about "car" with him/her..hahaha..She type in Chinese and I replied in English.. 
Mine still not ready coz i request the unit to be 240V instead of normal 110v or 220v..

Jasmine shipped my DV 337 on SAt.
I expected it on thurs. or fri. Got home from coffee at 9:30am tues. and up comes DHL with the amp.
Very fast .
I should have listened to the stock tubes to make sure there was no hum but no :-)
Put in the rca6080 and the Phillips, should get the rca 6as7's in a few days.
Sure enough there is the hum. So I'll wait 4 hours and post some impressions after the tubes burn in.

The Phillips 6SJ7WGT's took more than 24 hours burn in to stop humming for me, but eventually they did become dead quiet.

24 hours? wow, wish I had listened some stock.
Thanks for letting me know that so I won't go all audiophile nervosa after 4 hours.
It's been 3 hours now and the hum has decreased in the left chanel a lot but has not decreased as much in the right channel.
I haven't messed with tubes for a long time and I did not line up the 1st tube properly and pushed down some on the tube socket. I hope I didn't mess up anything.
I am getting music through both channels and the amp sounds good when loud enough to drown out the hum/buzz :-) So everything should be OK.
Chanel matching seems easy so far.
I think I will be very happy with this amp.
Is it unusual for the hum to subside unevenly from each channel?
The unfortunate thing is I will have to go through this again when I swap out the 6080 for the 6AS7 when they arrive at the end of the week :-(

A. Not sure, but it has been in my case. The hum went from left channel, to right channel, and then it went away.
B. Not necessarily. The tubes could be "hum free". Some tubes have hum, some don't. You won't have this hum every time you swap tubes. It is possible some have "hum" that will never go away, but most go away after 24-48 hours, but may take even longer.
For instance my RCA smoked glass 6SN7GTB took nearly 100 hours to be totally hum free. Yes, the hum was decreased hour-by-hour, but it wasn't totally gone for two weeks.. and I'm glad I waited, because this tube is really nice w/out the hum.

True. Only one of the six tubes I own has any hum. I assume it would have gone away over time, but I was impatient and since I had others, I replaced it and will keep that one as a spare...

Thanks for the help, guys.
I also assume I didn't mess up the tube socket since I,m getting (great) sound from both chanels.
I will try to channel Yoda and be patient.
After all, I'm on the Xin list, what's a few days to see if hum goes away :-)

4 hours and the hum is almost completely gone in the left channel and MUCH subsided in the right, enough so that I can do some real listening.
I put on Stravinsky and I must say I am very impressed ! I don't want to say much this early on but , wow.
Thanks , a whole lot, Skylab and Mazuki. It was your feedback that convinced me to get this amp, and it is some amp.
Orchestral bass is magnificent, incredible dynamics, beatiful rendering of string tone.
But I better shut up and give a few days to take it all in before saying more.

tomtjx, I know you mentioned you didnt listen at all with the stock tubes, but I wonder if you can check if you have any humming with the stock tubes.
I'm curious about whether jasmine checks for this when they "burn-in" your amp.
I'd hate to have to ship back a 15kg amp if it werent checked before shipping 
Thanks, keep up posted on your experiences

FWIW, when I very briefly tried the stock tubes, there was no hum.
