Dredging up one of my old threads to reveal a happy ending.
Marc and I (Marc) were unable to get the F5 to play in any kind of stable manner back in May of 2009. Well Marc wanted some help with his new corner horn project this past weekend, and kind of as a way to entice me up there I guess, he broke the news that the F5 was alive and in top form.
It seems he spent a lot of time getting it to that point...new PCBs, major tweaks to the power supply and some resistors to play well with the K1000.
She looks and sounds fantastic! It's a little bit of a different flavor for the K1000, and a nice compliment to the β22. And it sounds amazing with my custom built speakers.
