Re: So They Are Really Building New Amps Under Dumble Name
Their explanations do not sound like this at all. Especially when they have a boot at NAMM with their new amps.

Re: So They Are Really Building New Amps Under Dumble Name
It kinda feels like they are trying to make a profit out of the situation.
Especially comes that way when they push the players to try and compare the originals with the “new” one.

Re: True Dumble stories as told by Rick Wheeler
Howard Alexander Dumble will go down in history as one of the greatest amp builders of all time. Not just for how incredible and unique they sound but for all the great recorded music they were used on. I thought about how over time, history can become diluted, altered and even cleansed. For this r...

Re: 11 Step High and Low Filter Section
Since the low filter is basically a 1M RA pot , I’d say simply divide the existing resistor values such that you’re about 85% through the resistance about 1/2 way through the rotation. Basically you get smaller increments. The high filter you can add in-between values, lower values, or higher value...

Re: Dumbleland Special 150w ser#009 Schematic
Do we have a consensus/most practical way to implement the power supply for 520 Volt plate voltage without UL taps? Also would a Twin Reverb PT enough for that kind of high voltage? One of these Hammond 300 series Power Tranies should work for you 373HX / 373JX. Make sure chassis is at least 12 AWG...

Re: SSS #007
SVT story makes the pi/driver DC coupled but as far as I can understand Dumble did not use dc coupled setup with 12au7/12bh7 combination. Still a big what if to me. Wouldn’t be the first time that Dumble veered off documented historical precedent Ofc. But since Dumbleland was also AC Coupled(Which ...
