OK..so I got the Crate together after changing filter caps ,and some tone stack components. Tubes in ,power on, no input , I'm getting a very loud hum. So...when it cools I'll take a look at my work. Note: I had to alter the filter cap placement because they were taller , so they are laying over as opposed to standing. I changed a couple of resistor values ,and wattage in the tone circuit ,as well as cap value.
I switched to the dirty channel ,and it is quiet as a church mouse. Plate voltage is 470 , Tube bias reading is 22.2 ma , tubes are JJ KT66.
I haven't tried much else yet . I will swap preamp tubes later after work.
Thanks
