Mark,
Someone on another forum pointed me to this thread. I just received a Juicy Music Blueberry Xtreme with Cream preamp recently. I originally owned it from 2007-2018, sold it, and just bought it back. It was "one that got away". I reached out the the buyer a year or so after selling it, and thankfully he thought of me before listing it again.
I opened it up to put tubes in and see that 2 traces to the rectifier bridge are lifting. The PCB looks like it took a lot of heat in the area of that bridge. The caps around the bridge also look to be cracked / drying out. Before I power it up I want to fix that up.
While I'm in there I'd like to implement a few mods you used to do: power supply mod, maxim mods, and 6H30 retrofit.
Is it possible to get a technical package / schematics?
My initial plan is to simply put a bigger bridge rectifier with a snubber circuit on the chassis and run wires where they need to go. That's an easy fix for the obvious issue, and it solves my short term need. I'll need more info to jump into the other mods.
Best,
Randy
