Quinn SDO-Reverb 183/102

Greg, so you like the short plate amperex in the d'lator? I was always under the impression that long plates were the choice in the d'lator.

Yeah the Amperex short plates are what most folks prefer in the D-lator position AFAIK. Yeah I prefer them in the D-lator Position and I highly recommend them to anyone. Even if they can't afford to load there whole amp with NOS tubes, at least try to find one for their D-lator.

They're just a rare find that's all. Sometimes they can be found on Ebay for about the same price as Telefunken Smooth plates (about $40-$60 a piece)

There is an old saying "Use the right tool for the job."
That is a great sounding rig, that really suits your playing.

[qtone]

Amp sounds great Greg ..

I might be leaning towards a two channel amp now so
my build spot is still open .

Working those details out still..
Waiting on Shads thoughts about that now.

Looking for the keeper so its important to get exactly what
your after.. Sounds like you found your keeper Greg that is awesome.

Keep the clips coming sounds killer..

[alvarezh]

Wonder how can you find time to sleep with such an awesome rig laying around the house! Dig your playing too.

Congrats to Shad also.

Enjoy it Greg !!!!

From what I read in this thread, a longplate tube seemed to be a little more popular choice for a d'lator.

After hearing this clip, it is obvious that there is still something I am searching for with my 102/183. Mine is basically 183 pre and 4x6L6 output. My amp does not have nearly the same level of bloom as Greg's Quinn. Shad makes one hell of an amp. Perhaps it is the EL34s, but I tend to think the bloom is due to something else and I can find it in my amp. I should say the bloom is there in my amp, but it only occurs when it is turned up LOUD. I mean LOUD and it is my impression that Greg's amp is not cranked that hard in his clips. Am I wrong? Greg, do you have that amp cranked in those clips? I should also mention that I am using NOS preamp tubes that I got from Greg.

Yes Chip, like I said in that thread, I like the long plates too but they're almost impossible to find so I use the short plates and I prefer them now, just to clarify. Other's may not...

Yeah man It's pretty loud enough to shake the camera and knock shit off the walls. The amps master Level is set at 1:00 and the Dumbleator's Return is set at around 10:00.

Try checking the lead dress 1st, that's always has a big impact on the amps sound, especially the OD sound.

To my knowledge my amp does not have any special NOS parts in it but I can't say for sure. (Shad maybe you can clarify?)

Adjusting the PI to where the amp's harmonic Feedback is at it's best is crucial to 183's blooming characteristics. I have a NOS Ge short plate in the PI too which helps also.

Ahh yes and I should also note that I have a Box with a Rotary toggle I made to switch different capacitance levels when I'm spec'ing out cut lengths of RG-400 cables.


This box is in the loop set at the .0022uf. So just a little bit of highs are rolled off (I mean just a slight roll off)

I like that box. Great idea.

[greiswig]

So do you just keep this box in the D-lator loop as a way to roll of highs?

[boldaslove6789]

Yeah I use it instead of having 10 foot RG-400 cables

Thanks for the info. Using the clock, 1:00 and 10:00 for instance, has very little meaning for me. It depends too much on the pot tapers for one thing. It helps me to know that you had the amp set very loud. It has been my assumption that 102/183 are capable of 'bloom into feedback' at much lower volume levels than many other amps such as Fender and Marshall. Perhaps that is not the correct assumption. My Express certainly achieves that at lower volume levels than all of the amps I have mentioned.

# 183 blooms at volumes so low, you have to put your ear up next to the speakers to even hear it. (Into a 4 12 even!) Shad found that out when he was playing it for himself. (No Dumbleator needed) My 183 clones do the same thing, except one of the MV pots goes from about whisper volume, to OFF in an instant. Need to get a pot with the taper perfectly tempered all the way down. Shad has a great ear, and the Quinn that I owned before he even looked inside #183 is proof of that. It is still one of the best sounding Dumble style amps I have ever played. (It was an HRM)

That is exactly what I thought I remembered hearing. Thanks for that info. TAG, I have a question and this has probably been stated many times before, but I just want to keep it straight. When you say bloom, do you mean it turns into feedback or something else? I clearly hear notes with the Les Paul that bloom into feedback from 0:12s to 0:15s in this clip.

Is that what you consider blooming? There was a long thread about blooming some time ago. I seem to remember that there was no single opinion about what blooming really is. Can we agree that that portion of Greg's clip is blooming?

Greg's amp does not appear to be cranked in that section of the clip, even though he says it is. I guess that's one of many reasons why clips can be deceiving.

[sonicmojo]

Here is a clip from Dr. Ika a while back that I consider a great example of bloom with a D-Style amp. To me it is a combination of the right guitar and amp with certain notes being more obvious than others due to frequency. Try the A notes, especially B string, 10th fret with light picking touch and neck pickup. You can hear it without an amp but the right amp/guitar/fingers will really pull this out on the subtle notes.

Great tone there! Love the girth and very musical grind
