And don't ask you how you know this.. lol ... you just barely put a tinsy drop and work it in.. and if you buy a heatsink for the top use cheap heatsink compound very sparingly and make sure you have a couple thousands clearance between the top of the chip and the heatsink so that no pressure goes on the ceramic because of heat expansion
50v because that's what's going to draw the amperes when the amp is finished... make sure you back that bias pot way down before you hit it with the 50v and bring it up slowly...or it could go into self oscillation
