Hi all
As you can see Alan is a triple AAA technical guy knows the why and where the devil is buried in the details. That is why he makes the outstanding gear he makes and why I say you can not go wrong forking over the $$ for a Carol Ann. He is also one of the nices guys I have ever met.
Cheers Ron from Pelham NH

Re: Settings of Joes Silver Jub?
Very useful info here. Thanks for sharing.
I always suspected the diodes were to blame for making some Jubilees sound great whilst others sound harsh. I flipped a black 2553 a few years back because I just couldn't get it to sound warm like my other Jubilee. Wish I'd known this info back then. I'd have tried a higher value small ceramic cap and if that didn't do it i'd start experimenting with the LEDs etc..

Re: Settings of Joes Silver Jub?
I can't quite get to the level of detail Alan has shared here (I'm the marketing end of it-and a Petroleum Engineer by first degree,MBA by second-which means I only have 3 hours of EE-but I do have an audio engineer and a software engineer as designers on staff), but we started with a Jub style layout, and converted it point to point(eyelet board for you purists), and then began to change things a bit. Ours still uses diodes in the Drive channel, but we have removed the rhythm clipping function and replaced it with a mid boost switch-which works on both channels, much like what we do on his superlead style amp. We use sozo caps, a bit more filtering, pec pots, mercury mag transformers, essentially the best components we can find. The big difference is in the clean channel, where we have wired in a tube treble boost pedal of our own design into the front end of the clean channel. this allows the clean channel(which was anemic in our opinion) to be boosted up so it can hang with the drive channel and have a little more sparkle. It has its own saturation and level control, so you can get a very loud clean independent of the drive channel and output master set up. It still shares the input gain and output mater, but with the added saturation and level control, you can dial in a big clean or a dirty rhythm sound that has same relative levels as the drive channel, making the switching function more useful. The saturation also lets you get to a black crowes and ac/dc set of tones on the clean channel that sound very plexish(like the 68 style). We also added a low and high input so joe could run a therimin easily into either channel setting. This amp will clean up very nicely on either the drive or the clean channel. So we tried to cure it of the known complaints without changing the character of the drive channel too much. Joe let us do what we wished on the clean channel. The half power switch is a bit different as well. The amp is dead quite vs the originals that have a bit of inherent noise(some more than others as Alan mentioned). The loop is great, and we have grafted it onto several of our other amp designs, with a few tweaks. The 50 watter is same layout, only the half power switch is replaced with a power dampening style control for stage volume. DonR

Hi Don, thanks for all the great information. Have prices been set for the Jub amps?
