what we all want, that funny feeling inside when you play her

[greiswig]

Me! Pick me! Pick me!

Well, I've sort of come to the conclusion that I am not going to get "the" D tone on my 2 x 6L6 amp.

Tom, I'd still love to compare amps some time. I'm just up the road... Our builds are a bit different, but I'm pretty darn happy with mine. Maybe I just need to have my ears tweaked by something better.

+1 for that....lets a/b/c the clone bill's making for you, a bludo, and the real deal...tag plays

Bills not making me a clone of mine. He is taking a atock Custom which I find OH so close mine, converting it to 100 watts, putting a loop bypass on so I can use no loop, there built in loop, or the Dumblator, and going over every part to make it sound as good as possible. The Customs sound incredible as is, and I even prefer some things it does to my Dumble. I believe it was a clone of Kimoks 50 watter, with a loop added.

it's not, Kimmock's Dumble is a Low plate Classic with a .01 CL2 Coupler

Is there anyway to use a computer and send signal thru an amp until the tranny is seasoned?? I'm imagining a soundbooth with an amp on for a week or two just just to work in the iron

I guess I just expected it to sound more like the clips I've heard here and YouTube.

Tony from VVT amps has really helped me a lot as well as this forum's information.
Scott, Gil, Henry Brandon, etc have suggested values and tips.

Right now I have everything tweaked to values suggested here.
It has two RCA blackplate power tubes, a vintage Sylvania in V1, a EHX right now at V2 and a JJ ECC83 in the PI.

2 x 12 with EVM 12L's in it.

It's been an elusive chase.
What's weird is when I hear those YouTube clips of some Ceriatone OTS amps, many seem to have the D tone.
Marinblues has an OTS and HRM both 50 watt and his amps sound like a Dumble.
I don't have a Esprit but I have a few strats, a few humbucker guitars and a tele with P90's in it.
Here is a comparison of the Ceria OTS and HRM, both 50 watts.

If I do happen to land on the D tone, I may not even like it permanently, but it would be nice to hear it from this amp just once.

The 330/500 switch is a cool feature and use mine all the time.. Another cool feature is to add an extra relay with a bright cap so it is in circuit on the clean channel and out on the OD.. The switch on the the front can engage it if you want it all the time..It's and easy mod and easily reversible if you ever decide to take it out..I personally don't like the bright cap engaged on the OD!!... A few suggestions..

these tubes may be part of the problem. i hate EHX tubes they sound like garbage to me. The JJ isnt bad but i think a JJ803s (long plate) will suit the dumble tone better (more detailed low mids and bass while also reducing noise)

My ceriatone sounded pretty good at first but it took a while to really open up, it just recently has and it sounds amazing, i put an old RCA i found in my basement in V2 and it sounds like a Bludo now. And i mean that in a good way

Note: i did a few easy mods which improved the tone including raising the V2b snubber to 600pf leaving the other at 330pf, added a fender choke, and clipped the .05uf cap on V1 i believe its a negative feedback cap(basicly it fattened both channels a bit)

I couldn't disagree more - I have yet to find an application where a JJ is the best choice (I don't build 6V6 amps so that may be the one exception). Feel free to send me all your EH tubes that you hate so much, they are my favorite 12AX7 in new builds.

[Structo]

Thanks for the thoughts.

I can't really blame any of this on the tubes.
I have run the gamit on them.

The only reason the EHX is in V2 is because the other day I was testing it and found V1 was getting noisy and V2 was ringing.

So I just grabbed the nearest ax7 and stuck it in there.

Usually I run a vintage ax7 in V1, a Chinese 9th gen in V2 and a JJ or vintage Sylvania or Raytheon in the PI.
So I do have decent tubes for it.

I've thought about installing a choke in this amp.
Do you guys think it is worth it?
I've read that it can smooth things out (tone)? Is that true?
I have a Hammond P-C194B (022699) is that the right one for a 50 watt?
Specs are 4 H, 90mA(DC).
Currently it resides in another 6V6 amp but I can pull it out if you think it will make my D'lite better.

I currently have a 330R choke resistor.
I take it I would have to adjust the dropping string if I put a choke in?
Just the first resistor to the PI?
I think I measured that choke at 100R when I got it.

I have 330pf snubbers on V2.
Still have the LNFB on V1.

Tag, if you have a mid boost then the Treble cap is .002uf, with a 390pf on the switch.

I may experiment more with those values.

Tony how are you switching this new relay?
Wouldn't it have to trigger off of the OD relay to work like that?

It seems when I first started tweaking this amp that the biggest improvement was when I first changed the PI plates to 120K/110K.

Currently my voltages are:

High plates on both V1 & V2. 5uf bypass on all.

V1 175v, 181v

V2 186v, 195v

V3 274v, 267v

5K1 swampers, 560R screen resistors

RCA 6L6GC 431v plate, 426v screens, biased at 35ma.

The amp is pretty much all changed to the Tweaked layout except for the PI plates are 120K/110K.

[dogears]

Hey Tom,

Try adjusting the string to get 200V-205V on V2. 195V-200V on V1. A PT putting out in the 450V range would be better IMO.

Let us know!

[heisthl]

If you are using a 1k as the the dropping string resistor for B+3 (like the layout) and can't get to 290 or 300 Volts on the PI with 120k & 110k plates there's either something wrong or the power transformer is probably not going to deliver the tonal goods.

Tony - please post the bright cap diagram you use for the both,clean only, OD only choices with one relay.
