load resistor for line out or attenuator i'd say

Try swap the output trans primary wires on pin 3 around

I had an ef86 channel in my 18 watt but got rid of it cause the tube went noisy as you describe.

Check your powertubes are matched try swap the phase inveter 12ax7

Hi does anyone know if concordes/k60 and wrecks have preamp tube shields on them?

I just did a test with 3 different types 500pf ceramic - standard brown disc type 500pf silver mica - flat sqaure vintage type 560pf polystyrene And you can hear a difference between all of them! This was on the treble tone stack cap as this cap has the most effect on the amps overall tone. (Treble ...

You can put zeners between the transformer center tap and chassis ground (or the bridge rectifier ground). Get 30V worth of zeneers perhaps 2x15volt 10watt zeners. Piece of cake.

Hi guys, first post long time listener!

Or does anyone have a schematic if this is not the case?
