Tim Gagan	Chandler tube driver schematic Anyone have a schematic for a Chandler tube driver they'd be willing to share? Thanks! Tim Gagan http://www.gaganbros.com The World's Only Double Doubleneck Lefthand Band

I'd also be interested in the differences between the pedal and the rack-mount (other than the addition of the Bias, Contour, Mid EQ, and Boost function). The pedal gets pretty good reviews but the rack-mount version gets mixed reviews. And I have an older 3-knob Tube Works Tube Driver that doesn't sound very good compared to a Chandler.

Tim, I do know that they do not run on the high plate voltages that are typically seen with 12AX7's. But there are several OD's that do such as: Soldano Supercharger, H&K Tube Factor, Matchless Hotbox, and I think the Budda Phatman runs on high plate voltages as well. There are probably others (S.I.B.?). Not that HV=Good or LV=Bad but I thought I'd mention it.

Tim Gagan	The plate voltages look ridiculously low to me: less than 9 volts on the wall wart version and less than 12 on the AC cord version. But then again, I'm used to looking at amp schematics rather than effect schematics.

aron	Tim, There's this schematic: http://www.muzique.com/schem/tubedrvr.gif Hope it helps...

Thanks for the link, Aron, but actually the one I'm working on has an AC cord rather than working off a wall wart. I don't know how applicable the wall wart schematic is, because the guy who owns the one I've got ahold of has 3 Chandler Tube Drivers, two with the AC cable, one with the wall wart. He says they are all different gain-wise, and the wall wart version is especially different than the other two--way hotter. He's opened them all up, too, and he says they're all layed out differently.

Firefly	I have the Chandler schem at home. Email me and I will send you a copy. It is definitely differnt than the tube works version. Now does anyone have the rackmount version schem???? Firefly

Philospher of Absolute Reality	I thought the Tubeworks 911 pedal was an exact copy. Has anyone compared the two? I'm a big EJ fan, and he uses the original alot, so I was considering getting the Tubeworks 911.
