where would you get jumper pins at?

post #1202 of 1974

A few have picked them up from shops that carry them for computers, seems they are pretty standard... Radio shack maybe?

 

Edit: didn't see that you might want those particular jumpers pictured above.... Not sure on those.

Usually there is a few spare jumpers packed with the bag that the cable came in.

ok, so just recieved my LD1+ and already love it! how are you supposed to clean these tubes exactly? also, the left one is already dark and the left chamber of my headphones sort of has a hum, up until you play the music, then you can't even tell it's there at all, and as I play music, it sort of dissappitates. The whole removing the jumber caps things was a little confusing because the booklet made it seem like tehre was more to it then just moving caps around/removing them. anyway...PICTURES:

Did you try to swap the tubes from side to side to see whether it presents something different? 

I think the hum you hear it is probably not a good thing. Did you try to contact David, I hear he is pretty good answering questions and giving support for his products.

 

My amp does not have a hum, however the light is uneven in the tubes, the left one is more dimmed than the right. Also are you using stock tubes? I ask this because from the picture your tube is different to mine, yours has got a star type disc at the top while mine is plain round. Mine is stock by the way.

amp doesn't hum anymore, now I'm more concerned with the burnt/dark color of the left tube.

I have the EF92 which LD1+ sells, upgraded to it when I made my purchase. Is that the mullard or no? also, how do you take off, put on the op amps? just unclip the sides and stuff? Thanks so much man for answering my questions.

The picture quality is cloudy but it appears it is just a darker getter coating. The coating can be silver like or dark depending on how the getter is deposit in the tube during manufacture. As long the getter is not white you are okay.

It does give the appearance that the tubes are from different batches.

yeah, I believe that's it. sorry, crappy cell phone quality. anyway, it just immediatly sort of turned that dark color while the other one still remains slightly clear. This thing sounds ridiculously smooth. I'm in love

I have two pairs of tubes coming my way, one pair of RCA and one pair of Mullard. In the mean time I am listening to the stock tubes and Opamp on my new LDI+, trying to listen  as much as I can since it is a very enjoyable amp to my ears, it is definitely my best amp purchase so far and it pair very well with my Grados and Beyer headphones. At the same time I'm kinda getting a bit anxious to crack this little gem open and start tube/opamp rolling ='D

You may want to buy a cheap chip puller:

But you may find inserting an opamp chip more difficult than extraction.

So you may want to invest in one of the many available IC insertion/extraction tools.
