[QUOTE="Mailman1971, post: 64418, member: 1367"] I had that happen to me as well. Did the amp play with the KT88's before it died? When I switched from EL34's to the KT88's I swapped the tubes... went to fire it up to bias it...nothing. just powered up like you mentioned. I had to put a pair of EL34's back in to get it to "spark" to life.... then I could bias the one pair of KT88's up to level. Then I shut it back down....pulled out the pair of EL34's, replaced them with the 2nd pair of KT88's and it fired up to let me bias them. Something about the Bias level of the El34s wouldnt get the KT88's working. Seems like a long drawn out process but it worked for me and took about 15 minutes once I went crazy trying to figure it out. :wink: [/QUOTE]
