Have you tried a different speaker?
I have a Celestion gold / G12H 2X12 and also a Boss Waza Tube Expander...both have the issue. I am away from the amp right now but will try to record something.
So you are using an attenuator with a pair of Alnicos on an SSS?
I built the exact same amp as Bills and used the same boards as he used in his Texas Flood and I can tell you there is nothing flabby about the low end. (I've used it as a Bass amp) The fist thing to go on mine are always the speakers
The Return/Mixer (in parallel mode) mixing the signal in I found the 250k to be about right. If I went any lower limited my range of wet/dry isolation made for a touchy control and hard to dial in on the fly during gigs. It was also prone to null spots as well (using rack mounted time delays) I trie...
Stephen Thanks for the chart. All of that makes sense. running it closer to saturation might help sustain give you some added compression and 2nd order harmonics . If we think about it acting somewhat like a volume pot (everything else being equal) it would also cut some bass For me the 10k IIRC was...
Gil Sorry for the delay as I got a last minute sub job in DC and the site went out last night. :roll: I didn't have a 15K pot on hand so it was a 50K and 25K pots. Both seemed to work OK. The only thing I noticed was there was a bit more compression when going to the lower value pots. It was pretty...
Shad told me in a PM when the layout was being diagramed and 183 blueprinted the R/J switch for the layout (double checked) and said that they functioned the same so he probably knew this before anyone here. He thought it was :lol: Can't argue with that :) but.... I have read in other posts and for...
Studying the pics of 183 and a Quinn TKT183 as well as being inside a clone of the original TKT183, the wiring is NOT as Shad diagramed it. They are all wired the same as #124. I don't think it makes any difference though FWIW. Ian Shad told me in a PM when the layout was being diagramed and 183 bl...
Yeah, I was talking the clean channel being low end heavy. I was considering Skyliner. It seems #189 is Skyliner, but with mega boost PAB. But as it is pretty easy to experiment, I'll go with Bluesmaster stack first and go from there (if needed). I've yet to build a Skyliner amp that suits me. But ...
Also, the Bluesmaster preamp with 22n caps in the tone stack seems rather low end heavy. Did you feel the need to trim of some of the low end? If your referring to the clean channel? No not really. I thought the clean channel was the best sounding part of the amp and well balanced. :D The OD is a d...
Sorry, bit of a clickbait title. But, I've sketched something in Visio that could be under the goop of Dumble ODS #189 (apart from the reverb of course). Some here have build the ripper. Mr. Albany being one of them IIRC. Couple of questions for those who've built the amp. How does it compare to th...
Um... Total derail. Can we get back to our regularly scheduled event? I don't know? I was rather enjoying the discussion on filter caps :D Tony Agreed. I think it is a derail to argue "Wow, he's on YouTube, what he says must be true... :lol:" Maybe he doesn't realize how much Phil contributes on Yo...
