I have no idea but it could be a rectifier. I've seen some with the coffee-can drum.

The one on the left is a glow discharge voltage regulator.

 

The one in the middle is also a glow discharge regulator

 

And the one on the right is a ballast tube used to drop line voltage in series connected tube radios.

Captain, if you don't pay attention, I will power down your amp!

Also for a amp that can direct drive headphones do you have a balanced source?  Or does the amp need phase inverter.

If the amp is to drive the headphones directly it will have to use tubes that handle high voltage.

That leaves the EL34 or 300B in audio tubes.  And it will have to use four of them.

My plan is to use existing amp (MA6900) to drive Stax with a energizer, not a dedicated Stax amp. The speaker side is just a bypass without any sonic added to it, then flip a switch is to the headphone side. The reason for tube is: a method of tonal control, or could use cap/resistor rolling, or the original idea of air variable caps for treble/bass. I think i am going to have a few different Stax headphones with different tonal characteristics down the road, some may need to tame/boost the treble, some may need bass boost/tame, you know. Flexibility is one of the goals. I already ordered transformers that only suit for energizer use, I think.

 

Here are the custom made case (a pair) with hand rubbed hardwood, made in Washington State (support domestic economybiggrin.gif).

 

 

The Tango Transformers

 

 

The variable air caps are sure beautiful to eyes

Nice, very nice seamaster.

Is it a FPE case?

 

Clayton, Ultra is not responding well to his new position, we'll have to think again about a new captain.

Glenn will be permanently assigned to port duty.................all alone, nobody to help.

Why two cases ??

The transformers are tube amp push pull output transformers

That you are going to use in reverse .

We might be able to mount the variable capacitors on insulating plastic in that case and put on plastic knobs.

yes, they are push pull transforners. i thought that are what we need for a energizer. the second case is for next project, ha ha.

Ok let me know when you are ready to build this project.

We will have to discuss what to do to change the tone if we can't mount the capacitors.

Where is the RMMF going to be?

Does it have a port for our "Love Boat" to birth?
