Anyone know a good source for Bogen schematics? I found what I think is a Challenger CHA-30.
It's been painted unfortunately, but otherwise it looks original aside from whatever was added to the cover... can't find a Bogen schematic for this model though. Anyone know where to find one?
There's not much to those models with the 19 watt Coke bottle style output tubes!
If you want to mod it into something more guitar friendly then you do not need a schematic anyway.
What I will tell you is all of those wax caps are gonna need to go even if by chance they test ok right now!
When I die, I want to go like my Grandfather did, peacefully in his sleep.
Not screaming like the passengers in his car!
Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!
Thanks guys. Yeah there's not much to it... I can draw out a schematic... but before I mod it I just wanted to see how close it is now to original... doesn't look like much has been done. Usually I would just gut it and start fresh but I don't think I'll want to in this case. No doubt theres cap swaps in my future, but I'm going to put a new power cord on it and let it spend some time on the variac as it is and see what happens.
