Parts List & Mouser BOM:
Clementine Darling 1626 Parts List & Mouser BOM (Easy BOM entry link)
Power transformer is the Hammond 269EX, or 369EX for universal 120/240 line voltage. Output transformers are the Edcor GXSE15-8-5K (these are for 8 ohm speakers).
Clementine 6L6 (6L6GC/807/1625/6BG6) Parts List & Mouser BOM (Easy BOM entry link)*
Power transformer is the Edcor XPWR005-120. Output transformers are the Edcor GXSE15-8-5K (these are for 8 ohm speakers).
*Added two different values on the parts list and BOM for R18 & R19 depending on dissipation > or < 19W, selected for your power tube type. Changed R17 & R20 to 1.2K. Cathode networks are either 667 ohms or 720 ohms.
Also note that some old 6L6s need pin 1 and pin 8 to be jumpered together, as they are not internally connected. Go ahead and add them to V2 and V3 after you solder the socket in place. It can double as a cathode bias test point clip and permits EL34s to be used.

Notes:
4/25/13 - Added manual with more ULtra documents.
12/23/11 - Fixed the voltage chart for the Darling build that had pins 1 & 8 swapped. Fixed the 6L6 schematic cathode resistors (matches old parts list). Added printable board outline. Added FrontPanelExpress files. Still no ULtra notes. See my ULtra post until then.
