Looks like they are "A Frame" 6DJ8s. Should work nicely in the DAC60. The cap mod is simply replacing the big blue rectangle coupling caps with something better. The stock blue caps are right in front of the tubes. Hard to miss.
Here's a shot of my unit with the Sonicaps installed. I used 3.3 uF values (large units) with a bypass of 1uF IIRC. 200V works fine here. I'm going to open the unit up again for some mods soon and will take closer shots of the caps. Remember there are high voltages inside the unit. Do not attempt any mod without prior experience in doing this kind of thing. +-------------------------------------------------------------------+ |Filename: dac60 with damping rings jan 07.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=2418| +-------------------------------------------------------------------+ -- crooner SB3 with Custom Linear Power Supply Lite Audio DAC-60 Tube DAC VPI Scout with Benz Micro Glider M2 Audio Research PH3, SP16L and VS110 Vandersteen 2Ce signatures, 2W subwoofer. ------------------------------------------------------------------------ crooner's Profile: http://forums.slimdevices.com/member.php?userid=3379 View this thread: http://forums.slimdevices.com/showthread.php?t=20789 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
