I also had to remove the input transformer on channel 2, as there was a(t least one) bridge between the housing and the topside of the board. This was likely the cause of the whole shimmy sham, but it was good to get the jst headers off the bard and cleaned up. I’m now doing the bare wire install instead and feel more confident this way, albeit giving up the idea of quick-dismantling the preamp in the future.
I still think it’s easy enough to service.
Not quite done yet, but it’s safe to say I learned some valuable things along the way on this one.
I should have remembered the tips on Jeff’s (CAPI) site about mounting the 2622s; leaving a gap between the board and the housing of the transformer.
On remounting, I cut a piece of wide shrink tubing to sit below while the transformer got soldered in place.
Final recheck with the meter and all the connections are good!
Now to re-re-button this puppy up!
