| How good is the crossover in your loudspeakers? Running one of the last pairs of Northcreek crossovers for B&W Matrix 801 S2 that George Short ever built. Had him build the very important woofer Zobel circuit for each speaker too. Huge improvement over factory. Consider myself very lucky... | |
| glowing red output tube, but don't think it's red-plating Thank you all for an informative and helpful thread. Even kindness presented. That this can still happen on Audiogon means there’s still hope for us all 😊 | |
| glowing red output tube, but don't think it's red-plating @curiousjim - all is well now. The tube in question was just announcing it's demise. I intend to be much less dramatic with my own. A new tube, a quick bias routine and we're cooking with gas again. Really cranked it last night and both amps w... | |
| New vs uses in your current setup New purchases: tube monoblock amps, speaker cables, phono cartridge, output tubes, LiFePO4 batteries, LiFePO4 battery charger, speaker stands, preamp stand, speaker crossovers, 1 pair of rca cables Used purchases: 2 pairs rca cables, 4 power cabl... | |
| glowing red output tube, but don't think it's red-plating @wharfy - I sure don't miss horking those 75 lb. monsters onto the workbench! They are far and away the best sounding amps I've ever heard. Charlie said the same thing and he's heard a LOT of amps! For anyone who may be interested in a bit more... | |
| glowing red output tube, but don't think it's red-plating @wharfy the amps are custom made; the only two on earth. The original designer and person who initiated their build was Gary Dodd. He died before finishing them. 6 years later in 2021, his friend and colleague Charlie Cocci completed them and s... | |
| glowing red output tube, but don't think it's red-plating Ha! Thanks Ralph. I really wish I had thought of leaving the bias pot as is with the new tube to see where bias was. Oops. Not sure what runaway means, but instinctively, that seems like an apt description of what happened. Happily, popping a... | |
| glowing red output tube, but don't think it's red-plating No, they are two of a kind monoblocks. Complicated history, but short version: customer asked Gary Dodd in about 2014 to build the best amps he can. He designs these and starts building them. He dies. A friend and colleague of Gary’s inherits ... | |
| glowing red output tube, but don't think it's red-plating Thank you @immatthewj ; that is very helpful. The amps do have individual bias pots for each output tube. I certainly agree that the best course forward is to consider the bad actor tube as not fit for service and to be willing to move forward i... | |
| glowing red output tube, but don't think it's red-plating Not a lot of tube failures since the designer/builder helped me fix the bias circuit. It's two of a kind monoblocks. Previous failures were for sure wrong bias related. Now that can't be. Not important what mode of failure caused this really, ... | |
| Do most people prefer tight bass or non tight bass? The big ported 12 inch woofers on our Northcreek crossovered with custom Northcreek woofer zobel circuit Matrix 801 S2 speakers got tighter and go about a half octave lower going from a Jon Soderberg modified Threshold Stasis 2 with 250 watts per ... | |
| Would a tube amp generally do better on power conditioner than a SS amp? A balanced power supply is a wonderful thing. Two poles; one at 60 volts at 60 Hz, the other at -60 volts at 60 Hz. They are joined at the power supply plug-ins for perfect constant delivery of 120 volts at 60 Hz. | |
| Have you reached your end point with this addictive hobby? You are mistaken tony, at least with respect to me. I'm just here for the amusement provided by the antics of those for whom the answer is no. | |

| A life sentence!!! Cocci Ultimate Monoblocks. They're the only 2 on the planet. |
