Hi guys,   i haven't used the amp for a month and when i turned it back on i found that i have an unpleasant harsh sound which is present on both channels.  i have changed the preamp tubes which did not make it go away.  it is like distortion but  seems to show a very short decay when you play the strings.  sorry if this isn't clear but i doing my best.  Can anyone suggest what has gone wrong?  BTW it absolutely is not me being unable to tweak my amp it is a problem !!!! thanks, laurie

i have the Dave Gilmour EMG Strat set up and the mid boost on that really lights up the OTS.  it is a 12Db boost, so the 25Db Clapton boost would be even bigger, laurie

Send 1.0 o'clock
return 5.0 o'clock
 and recovery about 9.0 o'clock and up as i run the power amp at 5.0 to warm up the amp. i use the recovery as a volume control and like the sound a lot

black wire from OT goes to speaker jack ground tag, laurie

the red wire goes to the capacitor board middle part on the tube side

i put my OTS in a 2X12 cab open backed, and i love it!!   it has the Kleinulator and a TC G Sharp built into the top with the amp.

both brand new; the Plexi is around $1110 and the Twin is $800.  i built them myself and they are lovely sounding amps. the Plexi is in  sourmash head cab and the 5E8A is  a built chassis.  let me know if you want any other info that i can help you with, laurie

you are right on the colors so far.... the black goes to the speaker jacks [ground]

i did this mod courtesy of Mcinku' s layout and it does give an improved mids response. as i would never have used the FET input this is a good mod and relatively easy to do, too, laurie

could you post a wiring diagram as to how you did this?  i would like to keep the bright switch and remove the FET and replace it with the mid boost switch.  regards laurie

around 9-10.00 gives enough of what i like...laurie   i have done a few mods though

Hi! the last time i built a tube amp from scratch was 30 years ago and i managed to get the OTS right pretty much first time.  i have modded it a bit since then and it has given me immense satisfaction to have built such a fine sounding amp.  i say if you go at it carefully, it is do-able. it is a complex build, the hardest that Ceriatone make, i think [barring its 100 cousin, of course!]  on the other side the cost of having a first class build by Nik is ludicrously cheap; so you pays your money and makes your choice?? laurie

hi guys,
            i use a large open backed cab for my Overtone which has space on the top for 3 1U rack units........one has the TC Electronics G Sharp in it and i am wondering if Nik has any desire to build the Kleinulator into a rack unit.   i already have the Kleinulator and love it , but it would be a lot easier to use and transport if it were in rack form.  Any of you know about this???

sorry guys, screwed up on the gifs...here is the rig itself, laurie

 hi,
  I use a Steelsound 2X12 unported cab with a Celestion Classic Lead 80 and an Eminence 'The Governor".  The effects rack is aTC Electronics G sharp and i use a KLeinulator.  The pedals are a bypass for the TC, a simple MIDI change pedal and aPeteresen Strobostomp.  i use a home made 12VDC-9VDC convertor to run the MIDI pedal from the live side of the OTS PAB foot switch.  It works ok with rervations.
