Seeking the Ultimate Reference for Tubes

Hello All:

I’m searching for the best information out there on tubes. I’ve recently taken delivery of a new Lampizator TRP dac and have been digesting every forum post ever made with regards to rolling tubes in this unit. Something that provides base pin outs as well as cross reference/substitution data would be very helpful. I have a copy of SAMS Tube Substitution Handbook and although helpful it doesn’t seem to cover everything. Any recommendations would be greatly appreciated.
