The Framus Dragon and Cobra are essentially the same amp with a few different resistor and capacitor values to account for the difference in voicing and gain. I have a Framus Dragon that I want to fully convert over to Cobra specs, I already had the mid notch switches added and a resistor changed to get Cobra level gain years ago, but didn't get the capacitors swapped to change the voicing.
I know that I have seen a doc showing which capacitors and resistors to swap out for what values before, but can't for the life of me find a copy at the moment. Anyone have a copy, or know where I can find one?

You can find the schematics for each amp here: http://www.warwickbass.com/en/Framus--- ... nt_site_id
the main caps you want to change are the ones on the mid control. The cobra uses 22n caps and the dragon 10n. The dragon has a few slight differences to the james/bax tonestack too but the meat of the difference is in the mid scoop.
