Needed to separate the steel headband from the plastic yoke. All you need is a flat bladed knife. Insert it carefully between plastic and steel, then gently pull the metal piece out. Done. Clicks easily back into place. Some lubrication with a pencil will help if there's a squeak problem.   
My present everyday set-up:     Modified K500 connected balanced (two plugs), a special trick of the anode/cathode output of the Audiotailor Jade. Terrific sound stage and airiness. GEC 6AS7G (or Tung Sol 5998) output tube, Telefunken ECC808 driver tube (with adapter).     The standard K500 has a 1/8-1/4 inch plug, and if you've lost the adapter I've found a replacement.

 Give us your thoughts. Music played?
Pull out the tubes out, reinsert them a couple of times. Sand the pins if they're oxidized. Works 9 out of... 10 times.
 Hello, This amp may have been dicussed later in the thread, but I wonder if there are boards and transformer available from somewhere. Or maybe an even better, simple DIY amp design?
Found some pics that were maybe posted in other threads - look'em up, removal of the resistor network is worthwhile.       Here you see the three screws:     Driver assembly to the right - the soft plastic rim holds the cloth in place at the back of the driver (locked in place by the screws). Just to pull off when dismantled:       Driver assembly without cloth:     Pads had that special, comfortable and durable material (alcantara I think). Ear...
How do I remove the headband strap of the Gamma? It's probably a snap lock, but I don't want to break the plastic part.
