I would guess it will no longer go for under $500.

No need to replace the film caps as they will last another 30 years.  I would replace all the diodes though and UF4007's will do the trick.  Here are some Mouser part numbers:
 
667-EET-ED2G101BA
512-UF4007
667-EEU-FC1H471
667-EEU-FC1E221

Thank you spritzer.  incredibly helpful.  Just so I'm clear.  The red/orange film caps stay.  All diodes are changed to the uf4007, even the RA-1's.. and C008 stays?

I think it will go for around $725.00 with those headphones, based on what items have been selling for.

Magnavox electrostatic headphones?
 
Are these made by Stax?  Staxish looking connectors, low bias looks like.  Are these based on a known model?
(an eBay item, obviously)

I was wondering the same thing myself, silently watching that same auction.

These were made by Stax plus a bunch of others like them, Realistic, Marantz, etc.  The drivers were very similar to the SR-3N units but not electrically the same. 
 
Somebody unloaded a bunch of these on ebay some years back and I bought a few sets for fun.  All gone now though...

Is there anything to the rumor that Stax is working on a successor to its "top" current amps (the 727a and the 007t/ii)?
Or has the Stax takeover squashed that?
Thanks.

Thank you again, I'll place that order tonight.  One thing though.  The first Cap on the list is a "snap in" cap.  is that what I want?
 
 Just for my own knowledge, is C008 a film cap?

 

[Keithpgdrb]

I'll place my bet at about 550-650 on that ebay listing.

Dear god, the bidding's gone over-the-top on that one now!
 
Factoring in shipping, it's almost $645, which is within spitting distance of this $670 shipped SRM-T1.
 
Of course, there's still the whole solid-state vs. vacuum tube distinction, but I figured people would only pay up that much for the tube amps.

That's crazy. Especially with 3 days left.

The takeover has given them some much needed capital so now they can do some real R&D.  They will need to do it too since almost all the transistors they normally use have been discontinued, even the C5466...

The large PSU caps are always snap in on these things and C008 is indeed a film cap.  Anything square is normally a film cap.

update on malvalve amps
 
Today is a very enthusiastic article in the German magazine LP about he heamp 3 made by malvalve (4000Euro!)
It is an amp that can drive ALL kinds of headphones
dynamic / electrostatic / magnetostatic   and high efficient speakers.
 
Well I phoned malvalve to get more information about their headamp one (I on ly need one for electrostatic headphones)
 
The information I got is really astounding.
 
Their headamp one is basically an OTL poweramp without output transormers to drive a Stax headphone directly (about 100W!!!)
It is also possible to get switchable transformers to use this headphone amp with loudspeakers.
Their homepage is lacking information at the moment but they'll soon update.
 
They told me that in their expereince the difference between the different stax amps and their amps is larger than the difference between earspeakers?!
I'll try as soon as possible.
The only problem is that this heapamp one s about 6000Euro plus transormers for loudspeaker usage....
