Hi everyone!   My name is Jonas and I'm from Uppsala, Sweden.   Been working on this amp (12AU7 version) for a week or so after waiting for all parts to arrive. Maybe it's wise to state that this is my first real electrical project ever so I am a novice (who might make stupid novice...

  Judging from this picture: http://www.instructables.com/id/Headphone-Hybrid-Tube-Amp-SSMH/step3/Time-to-wire/   Looks like he has soldered the tube sockets to the aluminium housing in some way. How to do it? Maybe use epoxy glue instead?

Hi everyone!   I have decided to build one of these nice amps after viewing the Instructables-page of eh1080.   I'm wondering if anyone know or can guess how he fitted the tube sockets to the box without screws.   Cheers, Jonas
