[QUOTE="Maestro, post: 405061, member: 1686"] OK, from the top: The leakages on the KT66s were all tested, and all found to be excellent. On pin 1 of the EF86s I measured the following after warmup: Hungry amp: V1=105.1V, V2=89.3V. Normal amp: V1=109.5V, V2=99.3V None of the resistors have been renewed, as earlier in the thread you said to leave them as is for now. Over pin 2 and 7 of the KT66s I measure nothing on my voltmeter? That's why I switched it to AC, to see what I can measure. The heaters definitely light up, not sure why my meter shows 0V. I tapped and wiggled all the components, and had no audible noise or sparks or explosions, so I guess that is all good. I will contact you regarding shipping them to you - I have gone for long enough without hearing them! [/QUOTE]
