Tube Box DS, how do you get these friggin tubes out?

Postby mcgyver74 » 21 Apr 2017 00:23

So I picked up a matched set of 12AX7's to replace the stock tubes in my DS (I figure a little tube rollin is good :) ) Except, I cannot get the stock tubes out for the life of me. They have the heatsink on the tube, and it is EXACTLY the size of the hole the tube is in, furthermore you cannot grab onto the tubes at all to remove them....(they are recessed in the unit)

Does anyone know the magic trick to get these things out!??!
TIA :)

Hi,
you need to unscrew the two pillars with the rings that protect the tubes. This will expose the tubes. Then you need just to pull them out, with care..

You van add a tube safer and higher towers (or leave them off) if want to change them regularly.

Thanks everyone,

Actually the things on the top are not the shields I am talking about, those come off with 4 screws easily, if you look down in the holes there is a heat sink glued to the tube itself (A thing with fins) I can get the tube to rise a bit in the hole by wiggling it slightl (but I don't want to do that too much since I don't want to damage either a pin or the socket) but since the heatsink is the same size as the hole and the tubes are sunk so far, I cannot get a strong enough grip to pull them up past a point :(

I have 2 of the tube SE's and yes its a SOB to get the tubes out. I removed the 2 Guards Then you have got to wiggle the tubes loose and pull up at the same time. I never used the heat sinks or guards again. Getting them in is even more of a challenge since the circuit board will flex as you push down.Feels like you're going to snap it . Not the best design for constant tube rolling. I just replaced the 12ax7's with bugle boys and called it quits.

No that is not the solution, unfortunately.

I own both the Tube Box DS

and the DS+, that is very easy to open

That's the reason I was confused in my first reply above, which is obviously stupid if you inspect the Tube Box DS closer :mrgreen:

On the Tube Box, you need to remove the tubes (not easy, had to get help from a friend and a pair of thin tweezers to get them out, wiggle, pull and patience)
Then loosen the screws and you can slide out the actual ampilifier.
Unfortunately, rolling the tubes to the pair said friend kindly brought with him (JJ Gold something don't know the exact type) didn't bring any improvement to my ears.
So back to original and case closed ;)

ps: some sources mention the tubes are only used for impedance correction, i don't know if this is true, but would support my hearing abilities :D

ps2: very thin tweezers can grap the cooling element around the tubes

you must remove them...carefully...I was remove those covers and then when i finally remove tubes i decide to not putt those covers back...(just a cloth over when is not on). Btw tubes in DS have a great impact on sound...i didn't like stock tubes so i change them with some NOS RFT that i have somewhere from some old tube preamp...this a really good but they didnt last long...now i have some Siemens NOS which is more detailed but i still like RFT more...
