I do not -- I had to sell it while I was unemployed -- but I am definitely buying another one sometime soon. It's awesome.

@Swervecity413 @Thetorch777 Hi both. I'm documenting the early blue-board Bogner Marshall mods, and the solder-side photo of the 2x12's board in this thread (IMG_0132) has been really valuable. Thanks for posting it.
Does either of you have a straight-on, full-resolution photo of the component side of that blue board (the side with the tubes and parts)? Even an unposted camera-roll shot from when it was open would help a lot. No need to interpret anything, just the original image file. If the amp's ever in for service, a photo then would be amazing (only if a tech is doing it, as the caps can bite).
Thanks either way!

+1 to this ^ It'd be really nice if the guys grabbing up all these rare amps to collect or profile would share some / more gut shots of these things. It's not really gonna instantly devalue anything, IMO. In any case, no idea on how far along you are on this research but a lot of these Bogner mods with the blue boards are variants of what he designed for the Triple Giant Sharp channel. 4 stagers, 330k plate resistors on the middle 2, aggressive bass roll-off between stages 2 and 3, plate fed tone stack - basically Bogner's take on what ENGL does for their lead channels, but with a lot of small variations between each of the Bogners. A couple unusual ones have the tone stack of a Marshall 2555... If you've been at this a while, you probably already knew all of this, though.

@Thetorch777 @Swervecity413 Quick follow-up, and thanks Higgs for the +1.
Thetorch777, I think you ended up with Swervecity's Bogner modded 4103 2x12? If so, the one shot that would help me most is a straight-on photo of the parts side of the blue board (the side with the tubes and components), as the original camera file.
Only if it's ever open with a tech anyway, no need to pull anything apart just for this, the filter caps can bite. Swervecity, if you happen to have one in your camera roll from when it was open, that'd be just as good.
Thanks either way, much appreciated!
