Exactly, since the amp has the correct voltages on the output tubes and phaseinverter (v3), it doesn't sound likely that the powertransformer should be connected wrong.

More likely that you have wired the amp wrong.

No, I sounds absolutely wrong.

Turn of the power and check all wiring in your amp.

Use the 'layout' on the ceriatone webpage. If your amp is the latest overtone version, then use http://ceriatone.com/images/layoutPic/OvertoneLayout/Overtone-Special-V2.jpg

Check every single wire, one at the time.

It sounds like your have made an error in the PSU wiring, so check this part of the thorughly.

This is the best peice of advise I can provide you.

Hi Steven_NL, Erwin_we and others,

I have just posted some mods to the Kleinulator, which I think will bring it to sound more like the Dumblator:
http://ceriatoneforum.com/index.php?topic=1279.0

Would be very interested in hearing your repsonse and off course even more so, if your performed the mods to your klein and posted your response.

I have close listened to your clips. And it sounds like the Klein in your clip is darker than the Dumblator. You reported that the Dumblator, is compressing a little more than the klein. I hounstly belive that the mentioned mods will bring the two closer in regards to touch, feel, compression.

Dear all,

I'd like to hear your comments to the following mods done on Michael W. Kliens 'Kleinulator'.

- bridged/removed the 33k input 'grit resistor on FET1
- removed the input 220p cap on FET1

- bridged the 100k input 'grid' resistor on FET2 with a 1.1n cap. = D'lator HP freq (1446 HZ)
- Added the LNF circuit, (10M+220n+10M) on FET2
- Changed the 1M input-to-ground resistor, on FET2, from to 220K

Using the Kelin i series, with a couple of pedals - a T-REX 'roommate' and T-REX 'replica'. I sounds nice and compresses nicely - even with the pedals off.

Settings
- both bright-switches off
- 'Mix' at 5 o'clock
- 'Send' at 12 0'clock
- 'Return' at 12 o'clock

Pedals adjustet to unity gain.

Since, I don't have a dumblator, it would be interesting if someone with both the klein and a d'lator clone, tried the mods on their clone and reported back about how the sounds compare. Due to the compression added by the mods, I have a feeling that its pretty close.

Erwin_we, Steven_nl? others?

Hi Lindswood,
Those are great tones. You call your amp unmodded, but which schematic (date of) did you use?

Yes, you have to install another relay, because both poles are used on the OD/CL realy. However, you just have to connect the new realy to the plus side and minus side og the OD/CL relay and wupti, you can put the bright cap on pole and the mid cap on the other if you like.

yes, by putting on a relay that you connect to the OD/Clean relay.

I just done the same to the mid boost, so it only comes into play, when I engage the OD.

Live, its just the 2290 delay unit.

Studio, off course, they use all the effects needed to make the best of the recorded sound, in order to sell more records. 

However, RF's tone has evolved over the years. IMO his latest record 'Truth' is indead a very true tone, that sounds like natural tube tones and not very massaged......From what I have read he use the 12-65, but has experimented with eminence speakers lately, replacing one of the speakers in his 12-65configured, 2x12 cab with a red chassis emi. I believe he has tried a RWB or ToneTonker.

I'm sure I understand what you mean. You want to measure the AC voltage to/from the transformer??

Please remember that you are dealing with lethal voltages inside a tube amp. Leave it alone if you feel insecure and take it to a qualified technicial!!

Ok, so its clear that the problem is between the phaseinverter V3 and V1+V2.

Check your power dropping string 'point L' and 'Point M' on the Ceriatone schematic, to see if the problem is in the PSU, somewhere.
Also check very carefully, that you have wired V1 and V2 correctly.

This friday I make clips. Just a little patience

OK,
I enjoyed your D'later/Klein comparison file.

And I wonder if the Klein could be modified to sound like a D'lator, by adding

- 500p/220k intrance filter 
- 44m/50n LNFB network

to FET2. What do you think?
