Removing the old trident from the Bii is pain in the back, I'm thinking of just changing the error amp. Russ, is it ok just replace the old error amp with new one? Any other component need to add or change?
Thanks.

Sorry, but I don't see the issue with removing the original Tridents. I simply melted the solder where the pins from the main board connected to the Trident (In, Ground and Out) and gently pulled the old Trident off the pins. Then I floated the new Tridents onto the same pins. Took five minutes (and that included heating up the iron)

Of course, the Clock reg was on a plug in header which made swapping rather easier!

Russ, you could make the boards a fraction more DIY friendly by increasing the diameter of the leaded-holes just a bit. When you have a tight fit and a 2 layer board the removal procedure is tricky . Both suction wick and tool are struggling reaching the solder and the risk of damaging the via is imminent.
I did it easy with a normal solder iron. Just heat all the legs at a time and you can pull it out. Heat the joints and slay the board in your left hand into a table. Carefull only your hand shall hit the table. For Gods sake not the board.

Ok those of you who asked for an updated AVCC module (like the trident) - you now have one.

OK, so my new AVCC regulators were one of the most cost effective upgrades to date on my BII. I was wondering if others have changed both the AVCC and the Tridents, and could compare/contrast what they thought. I have a couple of extra sets of Tridents here, and wonder if it is going to be worth it considering I will essentially be throwing these away for lack of further need. Furthermore, I will not be using the VO as I am synchronously clocking.

A solder sucker comes in handy for desoldering. They range in price from a few bucks to hundreds, like the Hako 808.

Ha, What a tool! Serious, nice tool.

A buddy of mine has the Hako. It is nice! If I recap this Krell pre I have, I'll be begging/borrowing the Hako. I have the other one...a single shot.
