Re: #102 "System" In a Box Build
Hi Aaron - if you're still around..... and BTW - Happy New Year... I'm working on a copy of the Sonorus, but at the same time I'm working on a schematic that will present the amp as a complete circuit for later use ( when I'm not available... no one in this region has ever seen or heard a Dumble am...

Re: PS: More About Dumbleator Settings
My way around the loop cable tone loss is to put my pedals (Boss MD-500 and RV-500) on top of the amp and control them via MIDI. I had previously tried a Klon style buffer running at 24volts (to avoid clipping the buffer) after the D-Lator send, but found that it altered the tone in a way that I did...

Re: Jazz Mode Video Demo With Stratocaster and 102
I have the master bright cap on a switch and run it with the cap disconnected when I'm not using a Dumbleator, or if the master isn't cranked way up. I also have the gain (od level) control set up with a dual-pot that gradually brings in an HF taper as a turn it up. That evens out the brightness of ...

Re: Jazz mode is cool??
Yes. I use Jazz mode all the time when I play live. It's a much more focused and articulate sound IMHO. The key is cranking the input gain and generally running the tone controls higher.

Re: #102 Robben Ford Amp
Here's a variation on the #102 layout that I created and used with my amp build. It works with the CE chassis and Showman / Twin transformers, uses the precision power supply, adds a LNFB switch and incorporates a treble reduction network on the switching jacks of the loop. Hopefully it will be hel...

Re: Shouldn't every ODS clone have a built in Dumbleator?
I need to take a good look and see what's actually needed to change the #102 to full low plate first. IIRC it's just the 8 resistors, V1&V2 plates and cathodes. Thread where I talk about converting 102 to lowplate (with clips): https://ampgarage.com/forum/viewtopic.php?p=326945#p326945 -Aaron

Re: Shouldn't every ODS clone have a built in Dumbleator?
FWIW, I had my 102 Clone running with low plates for a while. I was using the amp to experiment with the different topologies and learn how they affected the sound. First I converted the 102 to lowplate (retaining everything else from the schematic), then I turned it into a lowplate classic, then I ...

Re: Bonamassa-Dumbles 2018
I started getting into the Jazz setting when I had my amp wired up with the classic tone stack. With the deep engaged that was my favorite setting with that configuration. I've since started using Jazz mode with the Skyliner, albeit without the Deep setting (or mid boost). On the Skyliners you can j...

Re: Why Dumble cleans?
The trouble with the Jazz position is that the amp loses a lot of volume in this position. That's the initial reason why I never used it much at first. You need to crank the input volume and tone controls to compensate. Once you do that, it's pretty awesome. Like a Fender cranked to the sweet spot,...

Re: Treble pot on RF #102
Indeed. Is that a belton reverb brick in there? marcus Yes. It's actually using 2 v2 Belton bricks in parallel blending two differently filtered reverbs. Sounds great for always on reverb as long as you don't have the effects loop send cranked too high. I've actually moved over to a configuration w...

Re: Treble pot on RF #102
Dunno if this helps, but here's a layout of the original version of the amp I built from the thread above.
I've since realized that I actually used a 1M for the master not 250k. I've made a bunch of changes to the amp since then, though.

Re: Threw In the Towel with the Low Plate Classic
I prefer the low plates /skyliner in my main amps which are 100watts with big iron (MM Tweed Twin OT). I like the straight up 102 setup better in my 100 watt with '70s twin iron, though and I keep my original amp in my home studio configured that way. Ironically, I've deviated a lot circuit and setu...

Re: Regulated 24VDC from 12VAC
I put the 2200uF 25V caps in and so far so good. I'm also using ultra-fast diodes too so I'm guessing that helps with ripple. I'll probably re-do it later with higher voltage caps once I do a new PCB layout for the relay supply board.

Re: Regulated 24VDC from 12VAC
Looks like I can just replace two diodes with caps in my FWB to convert it to a full wave doubler. Do you think two 2200uF 25V caps would work (got a couple in my parts drawer), or am I pushing it on voltage rating?
