Thanks Doug, very neat solution! Does the resistors need to be able to handle any effect?Or just plain 0.5 w?

I don´t object to zeners per se, maybe thats the better route to take as you say. I have read somewhere that you could use a power resistor in series with CT to ground as well? Is this correct?
If I wanna order a zener, what do I need? Cathode in the base to ground right?

Ok and the easiest way to calculate the current will be?
Or will have to be measured?

I'm shooting for original B+ volts on a "2pc El84 Pool" with a Hammond PT (275 -275 VAC) I calculate that will render me rectified about 275 x 1.4 x0.95 = 366 VDC B+1 . That is about 30 volts over target from what I read here. The original use 260 VAC taps as I know and end up at about 335VDC B+1. I...

That'l break her in like a blond on prom night!

baaahaaa and get me evicted in the process! great!

What is the function for these to caps on the turretboard? Are they eq or is it something to do with voltage?

I'm thinking of running a portable cd player through the input for this burn in period. Would it work?

Yeah I'm sooo ashamed of myself! Did i like overflow the PI stage as well?

Finished my TW clone and it worked well but the sound of it was very hard sounding so I kinda lost interest in it. Today I decided to have another look at it again and guess what I found? One of the suppliers of components gave me OD with the value of 0.01uF instead of 0.1uF. What I wonder now is, h...

I tweaked a little to tame the brigthness in my TW and tested to remove the whole brigth switch from the circut. I lost nearly all gain and more the 50% of the volume! Can someone tell me whats going on there?

Thank you!

I saw on the schematics in the files section, that if you wanted to use only 2 EL84´s that you should change the normal 1k 25w resistor to an odd 1.7k?
Is this the case or what?
Thank you !

Got to be some extra MOJO there

Could be!
I just dialed in the bias , it sounds amazing as it is! Didn´t have to fiddle with anything.

Actually finished my first express yesterday on the 23rd, Ken you must be Santa Claus!

most exellent guys...I´m so lucky to have ya all!
Thank´s a million!
and Merry XMass to U!

Hello! I was in the thoughts of modding my valveking head to be able to adjust the bias. By looking at how it´s done on the 5150 model I came to the conclusion of replacing resistor R250 in the attached schematic. Can anyone with knowledge tell me if this is right? What value of the trimpot would yo...
