You can use them as rectifiers. 

 

Frank Cooter has used mercury vapor tubes in his builds.  High cool factor.

Yeah pretty crazy voltages too at around 800-1200v.

As I mentioned it a while back, here is a super small Stax tube amp.  

 

 

Design isn't finalized yet but this thing will not swing a whole lot of voltage (500+Vp-p) or be very powerful but it is cheap and cool.  The small PCB in the back is the HV supply which is driven off 12VDC which also powers the heaters.  It's a switcher but it was very cheap.  Fully balanced from input to output but not really portable as it needs 12W just to light up the tubes.

Would never work unless you want to stick a Stax logo on some high power DC lines?  300B's will glow blue sometimes and some other DHT's too.  There will be a 300B based Stax amp or two...

These tiny-little tubes are those that are used by Alo and Go-vibe on their portable amps (Continental and PortaTube)?

To SRS-002 owner, what is the size of the power adapter tip?

I posted the following elsewhere, but someone suggested that I should post it here. Sorry for the double posting. I would really appreciate all the help I can get, whether it's about fixing the driver or getting a new one. I love my Lambdas, but am not capable of buying a completely new set.

 

 

I have a pair of 6-pin Stax SR-Lambda that's driven by an amp + SRD-6. The left side, however, has minimum bass. There is little channel imbalance or any observable distortion on the left side, just a lack of bass. I have switched speaker cables, reversed channels in my computer, even resoldered all the joints on the phones, but still could not solve the problem. I understand that old Stax drivers may develop a channel imbalance, but mine are fine balance(volume)-wise.  Any insights as to how I may solve the problem?

No, they use low voltage tubes... these are the highest voltage ones I could find.  Highest power too...  redface.gif

It wouldn't be wise for a portable tube amp to use high powered mini tubes when the thing runs off batteries. lol

 

A 300B Stax amp sounds interesting. I'm all for the pretty tube glow and of cause - good sound. o2smile.gif

A spelling typo by someone who easily confuses SR009X and SR900X for example?

About what? I dont think it's a new model as the screenshot appears to be of a story from 2011
