hi, does anyone have the above amp? I have the non magnum and am looking at attempting the up grade myself. I'm after a photo of the inside of the amp under the cover if possible. Or any pointers anyone might have.
this is a list of the mods rogue do;

Stereo 90 and Tempest II Super Magnums ($695)

- Hex Fred diodes in bias supply
- Screen grid resistors upgraded
- Polypropylene bypass capacitors in filters
- Bypass coupling caps
- PRP resitors in all critical spots
- Cardas binding posts
-Cardas RCA jacks (ST90 only)
- Upgraded wiring
- Upgraded small signal tubes
- KT90 output tubes.

cheers adie
